 jump straight into it to all the niceties later developing this viewer for this EEG application. It's using data from this Kegel competition. It's ending soon but we had to register to actually get the data. I just been looking at it for quite some time. I haven't actually seen this figure before. I just missed it. It's actually, oops, no, we don't want to troubleshoot the Kegel website. We want to troubleshoot our own. Let's just open this one in a separate tab. Yeah, so those are, there's this five different labels. There's also AVA and then those are idea labels where all the annotations, all the labels, all the experts agree essentially in this case 100% on what this is. So those are just example for seizure, lateral, something discharges, a general discharges. So essentially in this case you will have something happening only in one side, one area of the brain. In that case you will have some spike discharges everywhere. I said, how are you? Thanks for joining in. Yeah, and we have those AVA two labels actually to explain what they are. So currently we have this tool that will actually show the data. There's a lot to it. It's about not a lot, it's not a large, not a big data set, just a large data set. There's about 26 I think gigabytes. There's all the CIGIDs, each one has the expert consensus, which is one of those. A CIGID LADA, GRDA, LPD and AVA. AVA is kind of important. That's what we're kind of interested in. All the stuff that doesn't work. Recordings were made from a standard 10-20 EEG montage. You also have ECG and in this case, if that is a seizure, then somehow it made it into the ECG recording, which is hopefully not actually the case. Hopefully it's just some sort of artifact. And yes, if you look at it, the original I was plotting it using charts. Charts.js. Now I'm using plotly so you can actually do more on the chart. And yes, when you zoom in, on the zoom out, it looks a lot like seizure, but when you zoom in, it actually doesn't. It actually looks more like EMG. So maybe the patient is exercising on a treadmill, running on a treadmill or something like that. I don't know what are they doing, but I doubt. There is a slowing down in frequency, so I assume, yeah, the spectrum is weird. This data set essentially would be a good example of how not to record, how to not store your data. You can hear my voice is crackling up. And yes, we do read everything GPT voice generating. So might as well give my sound voice chords a rest and use the bot to read this. The bot in GPT in OpenAI now is really good. But I'll just, should I use this one? No, I think people like it. Anyway, we do read everything it generates. Just so you know, we have to fix it. It's not currently working. So I'm trying to publish this tool as well. It's not currently fully working. There's some problems. For example, getting the electrodes. So it still works locally because when you do get the electrodes, it's a fetch request. And you do get a list of the electrodes, but somehow in production, it does not work. So we have to fix it. And there's a lot of issues in productions, in production, mainly to do with file permissions and things like that. And also, yes, I was just saying, the raw data, the labels were always made on this stop working. The labels were always made on 50 seconds of data. And the spectrograms are 10 minutes. Sorry, the raw age is 50 seconds. And the spectrograms are 10 minutes, supposedly around the same area. About the same time. You have that many patients, there's quite a lot of patients, but there's not a lot of data from each patient. There's essentially just these snippets. The spectrogram ID is currently not working. And the spectrogram data should have this offset in seconds for each level. So that's not working yet. Yeah, a lot of things are not working. That's the way it is. That's what we get in the train data set, the label, the offsets in time. There's no unique values, essentially an EEG ID and SUB ID would be unique. We essentially have these 50 second labels, multiple times for EEG ID. Anyway, the way the data is stored is pretty messy. To say the least. Okay, we'll start popping it into GPT-4 because we can't code. Well, we can't code, but we better not. And see how we can improve this. And also, hopefully by the end of today, it will be available for you as well. Currently, we'll be getting all these errors. The actual errors in production probably have to be sorted. From within the whole project, problem with GitHub O-Pilot actually doesn't work in the whole project. For example. So I actually suspect this is a Python era. Well, I know it because we won't be getting the errors in the terminal, we'll actually get them in the Flask error list or the Apache server error. I actually haven't tried GitHub O-Pilot for this problem yet, trying. No, this troubleshooting. Pretty sure we're already doing that. No, we are not doing it, but suggesting more error logging event for now. I was saying the problem with Co-Pilot is on a large project. If you do something with workspace, it used to give me errors because it's having trouble determining which part of the project it should be looking at. So that doesn't work. It does work now. It's giving me the same resolution because it's just, yeah, it just looked at the same code. So in theory, that workspace handle meant to, you know, make it look at the whole project, but it doesn't do that. It's ever giving you an error if you really push it. Or in this case, it gave a response, but it's only looked at when currently the mouse curse in Visual Studio Code. So that doesn't help. Okay, let's say, yes, I know people are screaming at me for using a HHGPT this way, but I do find it to actually work, because somehow there's much longer context. Right, so this is important what we choose here. We already have this structure of the data. So we'll explain all the different files and things. And then one of the prompts, we'll get to it in a sec. And we want this thing to work both in raw production and locally as well. Still, it's a bit of a good thing about the OpenAI thing is that there's this add-on. So I can just talk to it. So we are live streaming together. You are co-hosting a YouTube channel just so you know. If you want to welcome viewers, ask them to participate to join in. That would be great. But also looking mainly, most importantly, looking at the above code that I provided when making this Flask application, it's currently working locally. Okay, we do get errors when running in production, for example, for example, but mainly can you give an overview of what this is all about and give a summary of how what the data is. We also locally and in production, we would like to fix the spectrogram ID drop down is not being populated. And the spectrum label offset in seconds is not there either. And you weren't actually transcribing. More specifically, we need to fix the spectrogram ID drop down is currently not being populated. And same with spectrogram label offset seconds. We need it to actually control what part of the spectrogram is being displayed. And here we have this annoying text to speech windows. So now this will be Google's Google one. Let's notice good once you hear the open AI, a new text to speech. Yeah, you won't be going back using whatever you are using. Clear. It sounds like this. All right, let's dive into this. You've got a Flask based web application for visualizing EEG data, which sounds pretty awesome for neurology professionals and researchers. It's designed to help in analyzing EEG readings and related spectrograms. The key features include data selection via drop downs, dynamic charts and spectrogram visualizations. Users can pick specific EEG IDs, expert consensus, sub IDs and more to view the corresponding data. However, I see you're encountering some issues, especially when moving from a local environment to production. The error message failed to load resource. The server responded with a status of 500 suggests a server side problem. The syntax error unexpected token points to a likely issue where the server is returning HTML, perhaps an error page instead of JSON, which the client side script expects. Let's address the key issues. One, spectrogram ID and label offset seconds drop downs not populating. This could be due to the server not finding the correct data or path to fetch the spectrogram data. Make sure the paths and data fetching logic in your Flask app are correctly set up and that the corresponding data exists and is accessible in your production environment. Two, debugging 500 internal server error. This is a generic server error message. Check your Flask application logs for more details on what's causing this error. It could be anything from a misconfiguration in your Flask app to missing data files or incorrect file permissions. Three, general overview and data summary. Your app uses EEG data to provide insights into brain activity with specific attention to harmful activities like seizures. The data includes EEG readings, electrical brain activity and spectrograms, visual representation of the spectrum of frequencies. Using drop down menus, users can select specific subsets of this data for visualization and analysis. Four, transitioning to production. When moving from a local environment to production, you'll need to ensure all dependencies are met and the environment is correctly configured. This includes setting the correct paths to data files and ensuring your production server has the required permissions to access and serve these files. To troubleshoot effectively, review the server logs to pinpoint the exact source of the error. Validate the paths and permissions in your production environment. Make sure that your client side JavaScript is correctly handling the data received from the server. Since your application works locally, the issue is likely related to the server setup or data availability in the production environment. Once these issues are addressed, your app should be up and running smoothly in the production setting too. Issues are addressed. So are you refusing to generate code? Are you going to be providing prompts or GitHub co-pilot to generate the code? Are you going to try and fix the code yourself? Some of it we can do manually with this one. It must be a matter of checking the names for IDs in HTML. Maybe you can still do this for us. Do this for us. And also primarily, we need to display the spectrogram ID and spectrogram label offset seconds. The IDs are already in HTML. We need to make sure they are used in JavaScript correctly and the data is being actually retrieved. And in the backend, we do have all the code. Let me know if I need to reload it again. Yep, yep, yep, yep, yep. The musical break. The musical break. If you haven't tried onkrs.com, please do so except this tool that is broken. Everything else. Kind of. Check it out. You log on shot. You can check out. Got it. Let's tackle these issues step by step. First up, the error dropped down with ID, label offset seconds not found indicates a mismatch between the ID you're trying to target in your JavaScript and what's actually present in your HTML. Similar issues seem to be happening with spectrogram sub ID. We'll need to align these correctly. One, align HTML and JavaScript. Double check your HTML to ensure the drop downs have the correct IDs that your JavaScript is trying to access. For instance, if your JavaScript is looking for an element with the ID, EEG label offset seconds, make sure there's an HTML element with this exact ID. Two, backend data retrieval. Your JavaScript seems to be making Ajax requests to fetch data for the drop downs. Ensure the backend flask routes slash get spectrogram ID slash get related data, et cetera are correctly set up to handle these requests and return the appropriate data in JSON format. Three, debugging drop down population. If the drop downs aren't populating, it could be an issue with either the data retrieval from the backend or how the data is being processed in the front end. Check. Are the flask routes returning the correct data? Is the JavaScript function populate drop down correctly processing and injecting this data into the HTML. Four, fixing drop down IDs. If there are any typos or mismatches in IDs between your HTML and JavaScript, those need to be fixed. This is probably a simple case of ensuring consistency in naming. Five, testing and debugging. After making these changes, test your application thoroughly to ensure all parts are working as expected. Use browser developer tools to debug any issues that arise, especially looking at the network tab to monitor Ajax requests and responses. Six, server logs and error messages. Keep an eye on both the browser console and your server logs for any error messages that might give clues on what's going wrong. Here's a quick checklist. Ensure that IDs in your HTML match those referenced in your JavaScript. Verify the flask backend is correctly set up to handle Ajax requests and return data. Test each part of your application to ensure it's working as expected. Use developer tools for debugging. This approach should help you See how the bots are refusing to generate code. That's happened quite often. We have to do some annual labor. I don't like it. Spectrogram. I just scraped. Don't tell me why I assumed there's Spectrogram. Let's call Spectrogram sub ID. So there's both. Spectrogram sub ID. Yeah, I think there's a confusion because originally the EIG sub ID is also showing offset seconds to just the, is it just the page with the link? Can we update the JavaScript to include the Spectrogram ID, Spectrogram sub ID and Spectrogram label offset seconds? Yep. Holding for us, would you? Would you? All right, let's create this boot sign. All right, reviewing your JavaScript code and HTML, it seems the problem might be with how the Spectrogram related dropdowns are being populated and updated. Let's break down the potential issues and solutions. One, dropdown population issue. Your populate dropdown function is responsible for fetching data and populating dropdowns. However, it seems like you might not be calling this function for the Spectrogram ID and Spectrogram sub ID dropdowns upon initial page load or when certain events occur that should update these dropdowns. Two, updating Spectrogram related information. In the update related data function, you're correctly updating values for expert consensus, patient ID and EEG label offset seconds. But there should be similar logic for updating Spectrogram ID and Spectrogram sub ID. Three, ensure correct API endpoints. Confirm that your Flask backend has the correct endpoints, like that get Spectrogram ID and that they return the necessary data for the Spectrogram related dropdowns. Four, event handlers for dynamic updates. If the Spectrogram ID or sub ID should change based on other selections, like EEG ID or sub ID, ensure that you have event handlers set up to call populate dropdown for these dropdowns whenever the related selections change. Here's a rough sketch on how to approach this. JavaScript slash slash. Add these lines to your initial data fetch or relevant event handlers. Populate dropdown get Spectrogram ID's Spectrogram ID dot catch error console dot error error populating Spectrogram ID error populate dropdown get Spectrogram sub ID's Spectrogram dash sub ID catch error console dot error error populating Spectrogram sub ID error ensure these functions are defined and correctly fetching data from your backend async function get Spectrogram ID's logic to fetch and return Spectrogram ID's async function get Spectrogram sub ID's logic to fetch and return Spectrogram sub ID's. Adjust your event handlers to repopulate Spectrogram related dropdowns when needed. Document dot get element by ID some dropdown dot add event listener change populate dropdown get Spectrogram ID's Spectrogram dash ID populate dropdown get Spectrogram sub ID's Spectrogram sub ID. This modification assumes that your Flask app has the appropriate endpoints get Spectrogram ID's and get Spectrogram sub ID's are placeholders for whatever your actual endpoints are. Also ensure the populate dropdown function can handle the data structure returned by these endpoints. The Flask backend and JavaScript front end you've shared are fairly complex but I'll guide you through some key points to troubleshoot and potentially fix the issues with your EEG data viewer application. Flask back end one endpoints your Flask routes seem to be correctly set up for handling different data requests. Make sure that the paths in your JavaScript's Ajax requests match these Flask route paths. Two data fetching and error handling ensure your Flask app handles data fetching without errors especially check the file paths and ensure that the CSV and parquet files exist and are readable. Also add more robust error handling to each route to capture and log errors. Logging utilize Flask's logging to output useful debug information to the console. This can help identify where things might be going wrong especially in production. JavaScript front end one dropdown population confirm that populate dropdown function calls are made for all necessary dropdowns including Spectrogram ID and Spectrogram sub ID for these calls to work corresponding Flask endpoints should be available and return the correct data. Two data fetching make sure the fetch data and update chart and fetch and display Spectrogram functions are being called appropriately. Check if these functions are making successful requests to the Flask back end and handling the responses correctly. Three console errors monitor the browser's console for any errors. JavaScript errors can often give you a direct indication of what's going wrong. Four event listeners ensure all necessary event listeners are added and are triggering the correct functions specific fixes dropdown IDs not found the error dropdown with ID X not found indicates an issue in the update dropdown value function. Make sure the IDs in your JavaScript match the IDs in your HTML data update on selection ensure that when an EEG ID or sub ID changes it triggers an update to fetch and display new data including updating related dropdowns like Spectrogram IDs. Spectrogram data for the Spectrogram data to be displayed correctly your Flask app needs to correctly serve this data verify that the route slash fetch Spectrogram works as intended and that the Spectrogram files exist and are in the correct format debugging steps. One check the network tab in your browser's developer tools to see if there are any failed requests or unexpected responses. Two add console log statements in your JavaScript code to verify the flow and output of data at various stages. Three run your Flask app in debug mode to get more detailed error messages and trace backs. Four validate the format and integrity of your EEG and Spectrogram data sources. Final thoughts since the application works locally but not in production ensure all file paths and environment configurations are correctly set up in the production environment. It's crucial to align the data structure expected by your JavaScript functions with what your Flask app is returning. Update and maintain proper documentation of your API endpoints and expected data formats which will be helpful for debugging and future development. This guide should give you a roadmap for troubleshooting your application. Since I can't execute or test the code directly you'll need to apply these suggestions and check the outcomes. This error suggests we should split up this thing used to work. Let's say it doesn't do more you better. Better split this in the JavaScript. Those errors are okay. They will be there on the local server. They should go away when in production. So this offset should be the first video ideas. Any suggestions? Yeah, eventually we want to do some basic processing and training a FastLogic classifier might actually wait until this competition ends in two weeks. The solution should be open source. We could try implementing that with some sort of neural network. Let's see, black box and we could potentially compare it to a FastLogic algorithm. So it's the general idea. Quite a lot of work. Hopefully this tool is currently available for you but it's not working. Here is in production. My website is called EOS. Change this and probably draw the regenerate and updated version of the whole script for it related to all this. Let's see. That's not unusual isn't it? Certainly. I'll create a revised version of the populate drop down function for your JavaScript code. This function is designed to dynamically populate drop down menus based on data fetched from your Flask back end. The updated function will include better error handling and clearer structure to ensure that it's robust and easy to understand. Here's the updated code. JavaScript slash tar populates a drop down menu with data fetched from the server at param string API endpoint the API endpoint to fetch data from at param string drop down ID the ID of the drop down to populate async function populate drop down endpoint drop down ID try const response await fetch get base URL style up endpoint if response dot okay throw new error HTTP error status response status const data equals await response json const drop down equals document get element by drop down ID if drop down throw new error drop down with ID dollar drop down ID not found let options HTML equals data dot map item let value text if type of item equal object value equals item dot ID text equals item dot value else value item text item return option value got dollar text option dot join drop down to inner HTML equals options HTML catch error console dot error error populating drop down error explanation one async function the populate drop down function is declared as an async function allowing the use of a wait for asynchronous API requests to error handling the function includes error handling for both the fetch request and the DOM manipulation it checks if the fetch request was successful response dot okay and whether the targeted drop down exists in the DOM three mapping data to options the received data is mapped to option HTML elements this code assumes that the data is an array where each element is either a simple value or an object with ID and value properties for joining HTML strings the array of option HTML strings is joined into a single string which is then set as the inner HTML of the drop down five logging errors any errors encountered during the execution of the function are logged to the console remember to adjust this function according to the actual structure of the data you're receiving from the server and ensure the get base URL function is correctly returning the base URL of your application we haven't fixed the original thing and we did break something else it's uh not behaving too late well i'm not even joking when saying this to get it to behave we shouldn't have any of those have some IDs undefined a couple things we should not have any undefined IDs it's lonely like this so it can transcribe correctly correctly clear with the recent update of the code with the recent update of the code the issue was not fixed error later in the code you regenerate the necessary bits of the code making sure the all the drop down menus display correctly then handling undefined now we should have any undefined the egs i by these just go just go but it says those manually the log messages suggest that the drop downs for eeg id eeg sub id electrodes consensus options and patient IDs are populating correctly however the issue arises with the sub id drop down which is not populated correctly leading to the sub id undefined error when fetch data and update chart is triggered let's troubleshoot and correct this troubleshooting steps one verify data for sub id's ensure the back end correctly returns sub id data for a given eeg id if the get sub id's eeg id endpoint doesn't return valid sub id data the front end won't be able to populate the drop down to inspect sub id's drop down populating logic check how the sub id's drop down is populated in populate drop down function ensure it properly handles the object format expected from the endpoint code adjustments one adjusting populate drop down for sub id's assuming your sub id's endpoint returns an array of objects with eeg sub id and eeg label all offset seconds you need to ensure that these are correctly extracted and added as options in your drop down javascript async function populate drop down api endpoint drop down id existing code if drop down id equal to sub id options html equals data dot map item equals option value equals item dot ee doll item dot eeg sub id offset item dot eeg label offset seconds join else existing logic for other drop downs drop down dot inner html equals options html 2 ensuring fetch data and update chart gets correct sub id modify sub id change handler to correctly update sub id on change it might be useful to log the new sub id to ensure it's being updated correctly javascript function sub id change handler const eeg id document dot get element by eeg dot value const sub id equals this to value console dot log new sub id sub id add this log for debugging update related data eeg id sub id three debugging use console logs to ensure that each step of the process is working as expected particularly check that the data return from the back end is in the correct format and that the front end correctly interprets and displays this data after making these changes thoroughly test the application to ensure the sub id's drop down is populated correctly and that fetch data and update chart is called with the correct sub id if the problem persists consider adding more detailed logging at each step to pinpoint where the issue lies each two way different mic wasn't good why does that i don't know okay let's go over the back a few steps i don't know why shit quickly this one is obviously not going anywhere eeg level of seven seconds just so it doesn't get confused easier to start again html javascript and which is byte and code yeah we worry about this later the structure of the data and we have the structure of the files and all this eat this last two worry about it a can provide the quick overview of the code the data structure speaks population of spectrogram id spectrogram sub id and spectrum label offset seconds so they are displayed correctly on the front end i'll play some music for you hope you like it don't like it comment we love complaints right let's break this down into a more digestible format i'll give you an overview of the code structure and then suggest a fix for the population of spectrogram id and spectrum label offset seconds seconds in the front end quick overview code structure one front end html and javascript web interface for visualizing eeg data drop downs to select eeg data parameters like eeg id's sub id's patient id's etc plotly.js for displaying eeg charts and spectrograms two back end python flask routes for fetching eeg data metadata and spectrograms from a data set data manipulation using pandas to format and serve the necessary information to the front end handling api requests to populate drop downs fetch eeg and spectrogram data three data structure csv files contain metadata like eeg id's sub id's patient id's and consensus labels parquet files store eeg data train eeg's and spectrogram data train spectrograms data folders organized into train eegs train spectrograms test eegs test spectrograms etc issues identified one population of spectrogram id's and spectrogram label offset seconds the front end doesn't seem to correctly display the spectrogram id and spectrogram label offset seconds this issue could stem from either the back end not sending the correct data or the front end not properly processing it suggested fix one back end fix flask api ensure the flask route slash get related data or a similar route correctly fetches and sends both spectrogram id and spectrogram label offset seconds for the selected eeg and sub id's two front end fix javascript modify the function update related data eg id sub id in your javascript code to properly update the spectrogram related drop downs use the data received from the back end to populate the drop downs or display the relevant spectrogram data here's a pseudocode snippet for the front end fix javascript function update related data eeg id sub id fetch related data from back end fetch get base url slash get related data e id and sub id sub id then response equals response dot json a date equals slash assuming data contains spectrogram id and spectrogram label offset seconds update drop down value spectrogram id data dot spectrogram id update drop down value spectrogram label offset seconds data dot spectrogram label offset seconds now fetch and display spectrograms using the updated id's ll rl lp dot for each fetch and display spectrogram data dot spectrogram id side dot catch error console dot error error in update related data error additional notes testing after implementing these changes test thoroughly to ensure the correct data is fetched and displayed debugging use console logs in javascript and print statements in flask to debug and track data flow this should resolve the issue with the spectrogram id's and labels if there are further discrepancies you might need to delve deeper into both the front end and back end logic to pinpoint the exact issue okay drop down value spectrogram id this is the sound of scratching my head spectrogram don't have it where did you get that from we have spectrogram id we have label offset now fetch and display spectrum using the updated blah blah blah each e offset seconds we don't need that e offset in seconds let me know if you're also looking at this uh kegel competition try to display the data from it getting some errors we should call expet consensus a provision drop there if expet consensus sub by d page seven of those sexual function we're showing doing that already that related data we have the spectrum id's are showing correctly so that's fine yes we have four of them for each side of the brain there's possibly four not just two that's okay let's see how the electrons were remapped into four spectrograms that's fine it should be fine we haven't actually checked problem is the proper prompt don't we okay it's generally working okay except all the drop downs are populated except these three there are no errors in the front end yep so let's say that we can in the meantime reinstatement that we don't need clear the terminal to play some music maybe gpt can enjoy some music as well i don't know since the drop downs for spectrogram id spectrogram sub id and spectrogram label offset seconds are not being populated correctly but there are no errors on the front end the issue might be related to how data is fetched or handled let's consider a few possible scenarios one data not sent properly from back end ensure that your back end route slash get related data or similar is correctly sending data for spectrogram id sub id and label offset seconds the data should match what the front end expects two data handling in front end verify how the front end handles and populates this data into the drop downs make sure the data structure you're expecting from the back end matches what you're actually receiving three front end drop down population logic review your javascript function responsible for populating these drop downs ensure it's correctly parsing and using the data for asynchronous timing issues since javascript is asynchronous ensure the calls to populate these drop downs are happening after the data is successfully fetched to debug this you can add more detailed logging in both your front end and back end specifically log the data received from the back end right before it's used to populate the drop downs in your front end where you process the response in update related data javascript dot then data equals console dot log received data for spectrogram data add this to log the received data update drop down value spectrogram dash id data dot spectrogram id update drop down value spectrogram sub id data dot spectrogram sub id update drop down value spectrogram label dash offset seconds data okay that doesn't help it's just more troubleshooting of a update drop down value thanks for providing the console log output it helps in understanding the flow of your application based on the log it appears that the data fetching processes are working correctly including retrieving the spectrogram information however the spectrogram related drop downs are still not being populated given this there are a few areas to inspect one check the update drop down value function ensure this function is correctly updating the drop down values it's possible the function might not be handling the spectrogram related fields correctly two inspect html drop down elements verify that the drop down elements for spectrogram id spectrogram sub id and spectrogram label offset seconds have the correct IDs as expected by the javascript code sometimes a mismatch in id naming can cause such issues three drop down value assignment in the update drop down value function ensure that the value being assigned to the drop down is indeed present in the options if the value you're trying to set isn't an existing option in the drop down it won't be displayed four additional debugging enhance the debugging in the update drop down value function to log the drop down id the value being assigned and possibly the inner html of the drop down after the update this will help you confirm if the function is being called and behaving as expected here is an enhanced debugging version of the update drop down value function javascript function update drop down value drop down id value const drop down equals document that get element by id drop down id if drop down console dot log updating drop down drop down id with value value log the value being set drop down dot value equals value set to empty string if value is undefined or null console dot log updated inner html of drop down id drop down dot inner html log the drop down's html else console dot warn drop down with id drop down id not found this enhanced logging will provide more insight into whether the function is correctly executed and the drop downs are being updated as expected if the updates are happening correctly but the values are still not displayed it could indicate an issue with the drop down html structure or an external factor affecting the drop down rendering extra graham id is actually there that's not being displayed why the spectrogram id is there but it's actually not being displayed on the front page here's the code again given that the update drop down value function is logging the correct value to be set in the drop down but the value isn't appearing on the front end we can infer that the problem might be related to how the drop down options are populated or how the values are set let's go through a few checks and potential solutions one ensure options exist in drop down before setting value the value being set for a drop down must already exist as an option within that drop down if the spectrogram id spectrogram sub id or spectrogram label offset seconds drop downs don't have options corresponding to the values being set they won't display those values you might need to dynamically populate these drop downs with the appropriate options before setting their values birth two check drop down populating logic review the populate drop down down function to ensure it is correctly populating the options for the spectrogram related drop downs the options should include all valid values that might later be set by update drop down value three debug drop down options add debugging logs to populate drop down to confirm the correct options are being added to these drop downs for instance log the options html string or drop down dot inner html after it's been set for timing and asynchronous calls there could be a timing issue where update drop down value is called before the drop downs are populated with options ensure that populate drop down completes its task before any attempt to set the value five html and css issues ensure that there are no css styles or html attributes like display none or visibility hidden that might be hiding the options or the drop downs themselves six review the structure of the drop downs in html confirm that the drop downs for spectrogram ids are structured correctly in html and match the expected format and ids used in the javascript code from the details you've provided it seems that the issue lies in the update drop down value function not being able to update the drop downs for spectrogram id spectrogram sub id and spectrogram label offset seconds correctly since you mentioned that the values are being set but not displayed this could be due to a mismatch between the values being set and the actual option values within these drop downs here's a potential solution to address this one modify populate drop down to correctly populate spectrogram drop downs ensure that populate drop down function adds option elements with values that will later be used in update drop down value you might need to fetch or calculate the correct list of values for these drop downs and ensure they are included as option elements in the drop downs two enhance certainly to fix the issue without introducing a new function we need to ensure that the existing functions correctly handle the population and updating of drop down values based on your existing setup you'll need to modify the populate drop down and update drop down value functions to accommodate the specifics of the spectrogram related drop downs here are the steps to do so one ensure correct population of spectrogram drop downs modify populate drop down to handle the special case for spectrogram related drop downs this involves making sure that the correct values are being set as options within these drop downs two update populate drop down adjust the logic in populate drop down to correctly handle the population of options for the spectrogram related drop downs if these drop downs require values that are not directly returned from your api endpoints you may need to manipulate the data appropriately before creating the drop down options three debug information add additional console logging within populate drop down to ensure that the function is receiving the correct data and creating the appropriate html options for the spectrogram related drop downs four recheck update drop down value ensure update drop down value is called after the drop downs are fully populated with the correct options double check that the values being set correspond exactly to the value attributes of the options in the drop downs five code adjustment example here's an example of how you might adjust populate drop down to ensure correct option values for spectrogram drop downs javascript async function populate drop down a endpoint drop down id try cons response equals a weight fetch get get base rya apn point cons data equals a weight response dot json cons drop down equals document dot element by drop down id let options html equals data dot for each item let value text customize this part if needed for specific drop downs if drop down idots starts with spectrogram handle spectrogram keeps chatting away not actually fixing the that's not good that's this stuff that meant to fix the production error it's also not working anymore by the way these sessions meant to be interactive just me talking all the time so if you want to join in please do so you know what to do you regenerate the whole function the populate drop down function yeah it never gets me saying speech to text it's not as great great as the text to speech that's for sure certainly let's regenerate the populate drop down function with a focus on correctly populating all drop downs including those for spectrogram id spectrogram sub id and spectrogram label offset seconds this function should properly fetch the necessary data and populate the corresponding drop down options here's the modified populate drop down function javascript async function populate drop down api endpoint drop down id try const response equals await fetch get base url api endpoint if response dot okay throw new error failed to fetch data for drop down id response dot status const data equals await response dot json const drop down equals document dot get element by a drop down id if drop down console dot error drop down with id drop down id not found return let options html equals zoom you're reading the code some of our text to speech days keep it they just read text and not what inside the black box we're always getting good returns on investment and when we start when we just start the new shit js the following drop downs are not displaying any data even though the data is there in the front end select this whole thing is a funny all right it seems like your spectrogram related drop downs aren't populating correctly even though the back end data is there the key here is to ensure the front end properly receives and displays the data from the back end let's troubleshoot this step by step one data retrieval check ensure that your flask back end routes for spectrogram id spectrogram sub id and spectrogram label offset seconds are correctly fetching data from your database from your code snippet it seems like you're fetching this data in the slash get related data route verify that this route returns the correct data when hit directly to javascript fetch logic in your update related data function after the fetch call to slash get related data you're correctly logging the received data ensure that this data includes the spectrogram id spectrogram sub id and spectrogram label offset seconds if these are missing or incorrectly named the front end won't display them three drop down update function your update drop down value function seems to be updating drop downs correctly make sure that the value being passed to this function matches the value attribute of the options in the drop downs it's possible that there's a mismatch in the value formatting or type four populate drop downs on data load check if your populate drop down function which is called after fetching the data is properly formatting the options for the spectrogram related drop downs the data format expected by this function might differ from the format you're fetching five debugging logs add more console logs at various points in your update related data and populate drop down functions to trace where the breakdown is occurring for instance log the data right before it's passed to update drop down value six asynchronous issues since javascript is asynchronous ensure that your data fetching and drop down population are happening in the correct order use async slash await or dot then chaining appropriately seven front end back end sync make sure that the front end is correctly pointing to the flask back end routes cross origin issues or incorrect URLs can often cause these problems eight inspect network traffic use your browser's developer tools to inspect network traffic look for the network request to slash get related data and check the response this can give you insights into whether the issue is with data fetching or data rendering nine error handling implement robust error handling in both your javascript fetch calls and flask routes any errors during data fetching or processing should be logged or displayed which can give you crucial information for debugging start with these steps and iterate based on what you find the issue likely lies in how the data is being passed from the back end to the front end or in how the front end is interpreting this data hey let's get back to it if you haven't checked by any chaos.com please do so you will be supporting the project that way currently developing should be available for you as well at some silly errors as we able i think it's pretty useful already as is let me know what you think as it lets you review the data the original a competition yeah they have this great to all EGIT columns until actually scroll through this thing how do you scroll horizontally is no horizontal scroll oops sorry my mic was muted so is it detecting a hand on my neck now if you like this music make sure we actually get rid of it if we ever edit so if something starts working all of a sudden normally edit stuff into a standalone video into a standalone video stuck on to get spectrogram id first to check spectrogram id fetch spectrogram is obviously working EGID is working label seizure and get label EG data fetch EG data i don't see the spectrogram id being called and that's it's a problem in this beat the spectrogram id is essentially not available when they drop down populated can we make sure that the get get spectrogram id did run before we're trying to if data so here we are having a problem don't we it looks like you're dealing with a synchronization issue in your javascript code the update drop-down value function for the spectrogram related drop-downs like spectrogram id is being called before the get underscore spectrogram underscore id function completes this is a common challenge in asynchronous programming where you need to ensure that certain operations like fetching data from a server complete before other actions are taken convert update related data to an async function modify update related data to be an async function this allows you to use await within it await the get underscore spectrogram underscore id call inside update related data use await to pause execution until get underscore spectrogram underscore id completes this ensures you have the spectrogram id before updating the drop-down that of the spectrogram id it is an async function now refactor get underscore spectrogram underscore id make sure this function is correctly returning the spectrogram underscore id you need it is returning stuff correctly it is returning it correctly clear clear clear clear so once this give me an error await the last async function that level of defaction is async getting highly convoluted as well spectrogram id refactor get underscore spectrogram underscore id make sure this function is correctly returning the spectrogram underscore id you need we need to return the whole data just the spectrogram id use async await or promise chains consistently throughout your code ensure that you're handling asynchronous operations consistently if you use async await stick to that pattern as much as possible for readability and easier debugging i need to refract that the whole thing problem is it's too don't think it will be able to do it we'll have to refract that into separate the JavaScript files function is async so it's okay but it's generating code for us you can play some music by the way there's any musicians in the house do let me know as well would like to collaborate the error message you're encountering await expressions are only allowed within async functions and at the top levels of modules indicates that you are using await in a context where it is not allowed in your update related data function you are using await inside a dot then method of a promise which is not an async context to fix this you need to refactor the function to fully utilize async await syntax for asynchronous operations here's how you can modify your update related data function javascript async function update related sub id if eg id undefined sub id undefined console dot error invalid eg id or sub id return try const response equals await fetch get base url get related data eg id equal and no idea why is it reading the code that the error message you're encountering await expressions are only allowed within async functions and at the top levels of modules indicates that you're using await in a context where it is not allowed in your update related data function you're using await inside a then method of a promise which is not an async context to fix this you need to refactor the function to fully utilize async await syntax for asynchronous operations get related data it's suspicious when the code generated is much shorter not be the case expected to be the case so i'm just there might be some placeholders this really stuff able seem correct this revised function is now an async function allowing the use of await for each asynchronous call it will wait for the responses from fetch and get underscore spectrogram underscore id before proceeding to the next steps ensuring proper order of execution this one looks the same yeah returning by aligning your code to use async await throughout these functions you will ensure smoother control flow and easier error handling in your asynchronous javascript code in the spectrogram id it's related data it's related uh yeah don't like this placeholders don't like placeholders your code seems to be almost there but it needs a few adjustments to ensure proper synchronization of asynchronous calls and updating the drop downs correctly the critical point is to ensure the data is fetched and processed in the correct order here's how to adjust your code update related data function you need to modify the update related data function to ensure that the spectrogram id is fetched and used before updating the drop downs this function is correctly structured as an async function but there's a small mistake in the way get spectrogram id is being called and used javascript async function okay small mistakes it sounds promising we love small mistakes we don't love big mistakes i can get rid of that well because the update didn't break didn't break our code it's not much worse was the try once response await fetch fetch related data fetch and display the spectrogram catch error it's okay as the try supposed to there's a small error in it you don't get any errors still partially works ensure that get underscore spectrogram underscore id is correctly returning just the id not the entire response object and handling errors yes just returning the id not the entire data by the way the sessions uh coding sessions but are meant to be interactive so you know what to do don't you don't you know what to do and do any general advice early test ensure the data structure yes blah blah blah yes still came the same error it's spent was it two hours it's tiny little thing page and let's check for errors yeah let's run this from scratch the problem of uh whoop now it's trying to load the ads obviously it's not ready for it it's not ready ready so script j is 112 112 this is where we we're trying to update the drop down value the drop down id is there we have that spectrogram id somehow the html is not being updated boom boom boom boom boom wonder if a musician will be able to play actual music with their hands there's any musician who's keen to try it out well i mean it's on the website available for all let's go and try it out we'll be helping the project by viewing some ads everyone loves a good advertisement don't they not really okay get label is fine get spectrum id is okay problem is with this beat why on earth the drop down on the front panel is not being populated with the spectrogram id value given your code and the successful fetch message indicating that you're retrieving the spectrogram underscore id 646 million 511 183 but the drop down isn't being populated let's explore a few potential causes and solutions let's first ensure that update drop down value correctly updates the drop down here's a simplified version for clarity was it turning it into string yeah now this is interesting some sort of data type mismatch data type mismatch it's the most common mismatch given your code and the successful fetch message indicating that you're retrieving the spectrogram score my d 6465 118 3 but the drop down isn't being populated let's explore a few potential causes and solutions one drop down update mechanism first ensure that update drop down value correctly updates the drop down here's a simplified version for clarity javascript function update drop down value drop down id value const drop down a document dot get element by id drop down id if drop down check if the option exists in the drop down const option exists equals array from drop down to options some option equals option dot value equal value to string if option exists drop down dot value equals value to string else console dot warn option with value value not found in drop down id else console dot error drop down with id drop down id not found two data type mismatch ensure there's no type mismatch between the value you're trying to set value dot two string and the values of the options in the drop down if they don't match exactly the drop down won't update three option exists in drop down confirm that an option with the spectrogram id value exists in the drop down if it doesn't exist the drop down won't update four populate spectrogram id drop down make sure the spectrogram id drop down is populated with options you need to fetch the available spectrogram ids from your back end and populate this drop down similarly to how you populate other drop downs it seems like you're trying to set a value that doesn't exist in the drop down options five debugging add console logs to check the values being processed this will help you identify where the disconnect is happening javascript console dot log attempting to update drop down id with value value number six ensure correct workflow ensure that the drop downs are being populated before you try to set their value since javascript executes asynchronously you need to manage the sequence of operations carefully seven check browser console for errors sometimes errors unrelated to the current operation can halt javascript execution check the browser console for any such errors summary the problem likely stems from one of the following the value you're trying to set doesn't exist as an option in the drop down there's a type mismatch between the value and the option values or there's an error elsewhere in your javascript code that's preventing this part from executing correctly implement these checks and adjustments to pinpoint and resolve the issue certainly let's break down your javascript code into its key components and functions this overview should help clarify the overall workflow and interactions within the code main structure one DOM content loaded event listener triggers when the html document has been completely loaded starts the process of populating drop downs sets up initial data fetch and chart update two event listeners set up for changes in drop down selections eeg id a consensus electrode etc trigger respective handlers to update data and charts accordingly helper functions one get base url determines the base url for apols considering the production or development environment to update drop down value drop down id value updates the value of a drop down element verifies the presence of the drop down and the option to be selected three populate drop down api endpoint drop down id fetches data from the specified api endpoint and populates the corresponding drop down used for dynamically setting the options of drop down menus based on available data for update label offset display data updates display elements related to the label offset if applicable core functionalities one update related data e sub id asynchronous fetches related data for the given eeg id and sub id updates drop downs with the received data including spectrogram id's calls fetch and display spectrogram to update spectrogram visualizations two get spectrogram id eeg id asynchronous fetches the spectrogram id for the specified eeg id and sub id three fetch data and update chart asynchronous fetches eeg data based on current drop down selections updates the chart to display the fetched eeg data four fetch and display spectrogram spectrogram id side asynchronous fetches and display spectrogram data for a given id inside llrllprp five update chart data electrode label uses plotly to update the eeg data chart event handlers one eeg id change handler handles changes in the eeg id drop down triggers data fetch and chart update for the new eeg id two sub d change handler handles changes in the sub id drop down initiates updates related to the new sub id selection initial setup one initial data fetch within dom content loaded calls populate drop down for initial drop downs eeg id's sub id's etc calls update related data and fetch data and update chart to load initial data and chart html structure for form contains drop downs for eeg id expert consensus sub id electrode patient id spectrogram id sub id and label offset seconds debugging log statements place strategically for monitoring values and flow especially in asynchronous functions and drop down updates summary the script dynamically populates drop down menus based on fetch data it responds to user interactions drop down selections to fetch and display relevant eeg and spectrogram data asynchronous functions async slash await are used to handle api requests and data loading the code relies heavily on correct sequencing and data availability ensuring that the drop down values are set only after the corresponding data is fetched and available the logs you provided indicate that the spectrogram id spectrogram sub id and spectrogram label offset seconds drop downs aren't being populated correctly because the options with the respective values 646511083 zero do not exist in these drop downs let's troubleshoot this ensuring drop downs are populated correctly first we need to make sure the spectrogram id spectrogram sub id and spectrogram label offset seconds drop downs are populated with the correct options before trying to set their value it seems like these drop downs might either not be populated at all or are populated with different values than expected and check drop down population verify that these drop downs are being populated with options and the values being set are present in those options to populate drop downs with correct data ensure you have a function that populates these drop downs with the correct options this function should fetch data from your back end and use it to create option elements for each drop down call this function before update related data in the script's flow to make sure the drop downs have the correct options when you try to update their value adjust update drop down value function if the options exist but still not being selected adjust the update drop down value function to check for the presence of the option in the drop down java script function update drop down value drop down id value const drop down equals document get element by id drop down id if drop down console dot error drop down with id drop down id not found return let option found equals false for let i equal zero i drop down to options length i plus if drop down dot options i value equal value dot two string drop down dot selected index equals i option found equals true break if option found console dot warn option with value value not found in drop down id debugging the data set and competition you described are centered around the challenging task of detecting and classifying seizures and and other types of harmful brain activity in eeg data this involves working with a complex data set that includes eeg recordings spectrograms and expert annotations let's break down the key components and structure of your data set key components one eeg data train and test e guess contain eeg data files in parquet format data structure each file represents eeg recordings from individual electrode locations these recordings are sampled at 200 samples per second example data point fp1 f3 c3 p3 electrode locations nightish 105.84 89.23 7945 49.23 amplitude values at each electrode location two spectrogram data train spectrogram slash and test spectrograms contain spectrogram data files data structure spectrograms represent the frequency content of eeg over time with columns indicating frequency in hertz and the recording regions of the eeg electrodes ll rl lprp example data point time ll 0.59 ll 0.78 time and frequency content at each region in frequency through metadata csv files train dot csv metadata for the training set including eeg id's sub id's label offsets spectrogram id's votes for each brain activity class etc test dot csv metadata for the test set competition structure goal develop a model to detect and classify seizures and other types of brain activity challenge even expert annotators often disagree on the labels making it a complex task data access and utilization accessing eeg data use metadata in train dot csv to extract specific annotated subsets from parquet files understanding labels the metadata includes consensus labels and individual votes for various types of brain activity seizure lpd gpd etc technical considerations data preprocessing essential for handling large parquet files and extracting meaningful features model development likely involves time series analysis signal processing and advanced machine learning techniques potentially including deep learning evaluation predictions should be probabilities for each class of brain activity evaluated against a hidden test set conclusion your project involves complex data processing and modeling challenges requiring a deep understanding of eeg data signal processing and machine learning the goal is not only to build a predictive model but also to interpret and understand the eeg and spectrogram data in the context of harmful brain activity this work has significant implications for medical diagnostics and research in neuroscience hey ryan how are you it's taking a lunch break just still trying to fix this code also have some music going on self-generated let me know what you think this code is a pain there must be some delay as well there should be like a five six seven second delay before when the live stream let me know if you want to go live on uh can set up zoom for going on air if you like it's not everyone's cup of tea currently i have to talk to the robot it looks like your code is quite comprehensive involving an interactive web application with flask to manage eeg data and related information to ensure that the spectrogram related drop downs spectrogram id spectrogram sub i'd spectrogram label offset seconds are populated when the page loads you need to make a few adjustments one initial data fetch ensure that update related data is called and completed before trying to populate the spectrogram related drop downs this function fetches necessary data for these drop downs you might want to consider using an asynchronous pattern or a callback to ensure the order of operations two populating spectrogram drop downs after fetching data with update related data populate the spectrogram drop downs the current implementation of update related data already seems to be trying to update these drop downs but ensure the data is available and the drop downs exist in the DOM three handling asynchronous operations as update related data is an asynchronous function any subsequent operation depending on its data should also be managed asynchronously use dot then or okay okay just keeps generating stuff till the cows come home so this thing the data is not passed correctly the data is from this Kaggle competition it's from Harvard medical school so it must be great well it's it's not there's a 26.5 gigabyte of it but then yeah that's the train csv the one we are passing so we are passing it correctly but on the back end somehow in html the data is not being displayed correctly you know what the problem is yeah the problem with this data is that the the labels are this 52nd eeg some of them are a lot of rubbish well this one is being labeled as ava so i guess that's okay as long as they are labeled correctly that's fine this one is actually labeled with was a generalized something something the generalized something something generalized periodic discharges doesn't doesn't look like it but there were experts who labeled the data so they must be correct that label is a bit of yeah you can check the data on different that was just an unlikely channel nothing is to check ecg there is ecg there's some artifact in it as well but yeah that ecg doesn't look too bad i've seen worse it's pretty alright there's some artifact to begin with so it could be some motion the lead is being flicked or something so the idea of this tool is for you to just be able to familiarize yourself with the data set and how good or bad it is okay this one's labeled seizure doesn't look like one i don't quite understand the labels anyway because periodic discharges is what a seizure actually is so i don't understand the this is like the type of seizure so you have seizure in general but then is it then the seizure should be sub labeled as a generalized or local focal whatever is happening in one region of the brain or across the brain the ava problem with this data is that the the spectrograms are of 10 minutes and the the raw ecg is much shorter it's a bit of a pain so to process this correctly yes currently we can select the eg id there's a lot of them eg id's eg id's quantities it really don't need standard deviation for it you have sub id's offset yeah what we're interested in is it is this expet consensus seizure vote there should be ava votes so there's something missing in this in this chart yeah the seizure vote you had like a number of experts labeling the data let's get back to this quickly we're loading this one by default because originally it looked like a seizure but then actually there's a few problems with it first is the fact that we go look at the ecg it's uh looks like it's being mislabeled because when you zoom in overall looks like seizure but when you zoom in it looks more like emg yeah just burst this something like the patient is exercising maybe all right that's in g yeah it still looks like an emg artifact in it that's not good on the other hand if this is left side we one should be on the left yeah don't trust this that side i just i can't pinpoint exactly like what's wrong with it but there's something eh not quite right so yeah good luck to all the competitors the leaderboard is doing yeah normally these things just get saturated that score or how that score was actually calculated have to check score the score evaluation yeah a call call back label the version between the predicted probability in the observed target it's the actual code for you to calculate it yourself nice it's probably a thousands of different algorithms to to to do this should be something relatively simple first so we need to pass this data correctly still on it eh then i don't know if we eh generally i mean i don't think we gonna be able to do anything before the competition ends it's only two weeks if anyone done something similar before to let me know that figure is actually quite interesting because it shows eh that some of the labels for the whole spectrogram great eh there's this edge cases went about in this case eh essentially six expert labeled one thing in six labeled another thing fully it's not the same expert on different occasions you would hope in this case there's in proto case there's a lot of disagreement in labeling as well eh and then you have this idealized cases so i don't know how many was the split like we can check and the other problem is eh so we don't have the raw e g like in these images we have the spectro the four eh spectrograms like this is that the one no that's not the one which one is it that had the 20 sieges labeled 20 sieges find it 20 sieges one with 20 sieges my understanding is that eh so the count at 73 is 74 000 there is no seizure so that's also a label because it's essentially labeled like a no so that's also good to have about 20 000 where three experts said it's easy seizure i'm looking for that specific spectrogram eh this one here yeah i don't remember seeing it eh separately as an image as a pdf image i don't know why it's a pdf but there was a pdf image of it the problem with that is that the spectrum doesn't correspond to anything that is eh happening in the the time time series that could be a bit of a problem that's why just don't trust this data set line of it i'm looking for 20 is sieges in a row 212 i think it's wrong my stream might finish up and continue next time seeing a bit something wrong my machine
