 Let's see if we have the sound working and everything else video should be fine, sound in OBS says ok, but I don't actually know until it's coming into my ear, it is now. I can stop monitoring, hopefully it will remain the same. I'll just get back to where we left off, making an ACG feature extract web application using Flask Neurokit to NumPy. It should look something similar to this. The only difference is that the different ACG waveform components should be labeled, so there would be some labels over the PQRST, so PQRST waveforms, so peaks and troughs of this signal and there will be some parameters to control the algorithm and try to make labeling work better. So far we have this code that is working fairly well, the PNT marks are a bit off, QRS labeling is working correctly, so we'll try to improve on that as well. This one here is not a Flask application, we turned that into a Flask web app and it's currently only accessible on local server, but hopefully soon enough it will be available to you as well, however we have this couple of errors that we need to solve first. So first of all is this NumPy data array object has no attribute strip and GPT is suggesting us to transfer it to LIST, so let's see where is the data, should be the JSON file, turn data points, data, data, data, side packages, where is the actual page that the data is going from, it can't have that many lines, side packages, side packages is strip, anyhow it's in a Python code somewhere, where that variable, we call it twice, that's what's turning JSON and we have to convert it to LIST, the problem best place to do it would be over here, let's see if it works now, no it doesn't, same problem, so we are turning data into LIST, that's obviously not it, haven't solved the issue, the changing, changing to this, still, still gives this NumPy data array object has no attribute strip error, let's see what else we can do, yes let's tackle it systematically shall we, great idea, overpassing the data to essentially turn it into JSON array, to make sure that all the data can be serialized into JSON format, the funny thing is that we really solved this problem, similar problem before, but that part of code just disappeared, no where it went, chat GPT just decided to ignore it, that's okay, because we generally have the thing working, I know it's working, it should be a fairly easy fix, now it's doing all this troubleshooting, so before return JSON file, I want to print explicit response creation, creating response explicitly, so is it instead of a JSON, so I want to add response, it's not being currently used, that's fair enough, and now we need to instead of JSON, where was it, JSON file, I'll come more, where is our JSON file, here is our JSON file, I think this will be happening instead of JSON file, sure, return, return, this need to be identical to that JSON, wait, JSON file, so we're still using JSON file, ECG to list, so do we still need to turn data to list, because ECG is already being turned to list, I'm confused now, return, we can't have two returns, is that one, we'll have to go, have just the one return, we're using response data, leave the print there, pretty sure we don't need this one, because it's got replaced by that one, we do need to identity that way, I'm pretty sure, still part of that if request is post method, returning response data is JSON file, try that, whoop, whoop, the big chunky error, big chunky error resource, let's see if it picks on anything that is wrong, probably will mistake the flow of your root handler, you're using response only in post, yeah, why is it get, but when trying to return it for both get and post request, this would throw an error during get request, since responses data wouldn't have been defined, you should correct the flow of your function, correct the flow of your function now, okay so we have post duration hard rate, it's an integer, duration is float, okay shouldn't matter, we do still need that line, that's okay, printing, that's fine, get rid of that, now we have response JSON file ECG, that's the same error in message stream, what, haven't seen any of those before, hopefully that response was complete, so we're returning else return, who, index HTML just happened, we just use copy and it deleted my chat, why, I won't leave the website or something, let's regenerate that just to make sure that response also seemed to have been cut out, it's also pretty slow getting the same error, okay now we fix the theme, let's go here, copy all that, copy pasting is a skill you must have, we're still getting this error, let's see what it says, hopefully it's also responding quicker, okay what's going on, before the conversion to list types, when numpy is using miracle operation the nums in the numpy array might not be standard byte and integer of loads but rather numpy specific types, okay I didn't actually have to do that, which line of code, this actually gets triggered by actually getting five, is this with 500, is 500 and is it an error, no, I should be 200 ideally, no it is an error, no that's okay, so that's an error and that's the actual explanation to the error, how come the data type wasn't printed out or what, so sometimes code type ignore that in hopefully it will have a better idea of what's going on, make response as if it were a string, string, it's not a string, it's a response that a certain response, the first response is to generate hd here, should be a string containing the JSON data but there's just a receiving number seeing a numpy data array, ensuring the JSON server before passing the response, ensure the response that is indeed the JSON string passing to response is that note you need to import JSON, import JSON, just dumping it into JSON, need to import JSON, it's JSON, it's just JSON or is it important from a flask, port, assume, in JSON, JSON dumps, check the directory returns them and review, the function should have no directory return, print data, I don't want to print data but let's say absolutely have to, before calling JSON5, I thought I'm not using JSON5 anymore, before passing the response ensure it's indeed JSON string, check the return statement, inspect, generate this function double check, generate this gdata function and ensure the both return values data and ECG need numpy arrays before calling JSON5, so I still need JSON5, do some debugging over here, pretty sure we had too many prints now, type data, get the new printouts, still getting that 500, still getting 500, pop the whole thing in, see if it picks up on any mistakes, yeah, suspected to begin with, I did comment it out to begin with, didn't I? So if I could then again using JSON5 on the same data and so we're done, because here we have the print over there, so which one are you using, definitely don't need, don't need this, I need two prints, do I? This is the same thing, endpoint mismatch, your client-side JavaScript is making a post request too, but make sure you're consistent, okay, JSON5, generate ECG data, handle this endpoint is generate ECG data, make sure they're consistent, yeah, we have to do this first, just need more information on that, and yes, instead of JSON dumps, we use JSON5, I think it will work better, I'm not sure, we can try, compare between the two, see what difference, it's funny how most of the time if you give it the same sentence that it generated that becomes very apologetic, the root and the function name flask can be different without any issues, one thing is that the client-side request matches the defined root in the flask, why do I even have both post and get show, so if request is post, we do that, else just return html, turn that conversion, the main issues of if they're done in the JSON conversion and this pawns creation, please make sure that the client JavaScript makes post request too, JavaScript, post request, this is going to this URL, I don't think it's a post request, it's cool, it's fine, it's also if you if you bias the language, like if you actually ask how to modify, it is JavaScript, it will actually tell you how to modify, but if you ask, I suspect if you ask, oh is this correct, it might just say yes, it's correct, well I mean a bit like humans do, it doesn't, you can bias their responses fairly easily, to modify their blog.tcg function, you can just directly edit the code, you want to change the URL endpoint, what, new, what, and it doesn't seem, it's not right, that's not correct, just go here's the example, no asking specific, I think it's giving me something more general, let's stop generating this function error, don't have a function error, but that's should be okay, don't understand, is this, is this correct, is this, yes, JavaScript prevents post generate gdata endpoint, which matches the flask endpoint you defined in, so why am I still, why am I still getting the error then, data post specifies the htp method which is post, specifies the endpoint URL that matches the flask live app, don't check, generate dcg data method post, specify the endpoint matches the root, so that's okay, why am I still getting, so why am I getting all this stuff still, something to do with the type, it's not directly related to the mismatch and the endpoint scenario response construction, flask, flask is attempting to treat a numpy array object as a string which causes an error, okay, how do I fix it and data ecg and data to list, in particular there is something with how you are constructing the response data that flask doesn't like, let's refine the way you're creating JSON response to avoid this error and ensure that the values you're passing into JSON5 function are valid, JSON serializable types, ensure that when constructing the response you are not accidentally passing a numpy array, you have some print statements which I haven't actually made sure that the output of this print statements are types that are JSON serializable, at least in this case, then in your response construction, points, response data, make sure that the ecg to list and data are actually list and not numpy arrays as instead of, can simply, since JSON5 already prepares the data as a flask responsive application JSON, but I'm not, I'm still using the JSON dumps, I'm still having to answer the question, I don't even see those printouts, interesting I'm not getting the reach limit of prompts reached, even though in the past I'm pretty sure if I send this many prompts I would have got that error already and GPT would have downgraded me to use 3.5 instead of GPT4, your code seems appropriate, you're using flask response object and specifying the content types application chain manually, it approaches fine, okay, endpoint mismatch, ensure that the JavaScript Ajax request is making post request to the correct endpoint which you have defined, I think this is the correct endpoint generate ecg data, you've printed out the types of the data in ecg variables to ensure that they are of type list which is good, did I, actually why don't I see that printout, I don't know, response creation using the response object you have done should be suitable, however JSON5 is more straightforward and that's okay, it's just seeing here please provide the exact error message you see and that's the, it's clear, clear this for a sec and that's the error message, control shift c, current when making post request and not some other part of the application ensure that the data you are sending from the client side JavaScript matches that the flask endpoint expects, one more thing, while debugging might be helpful to add an error handling to your flask up to give more instant potential issues, smooth return errors and error messages response when there is 500 internal error, first this is the error I'm getting, error handler who just popped this, it needs to be in the event list now, so we'll have to it's probably in the beginning somewhere or here decorators, is this a thing, it is, oh wait, oops, I was trying to put it in the JavaScript, yeah we can put it at the beginning, I'll put it in here, oops, have to have that line first, in this case they shouldn't like supplication, they are caused by flask trying to treat response, the code of the problem lies in the flask return response is what you can do, it's just what, this is just forcing 200, okay, I didn't know you can do it, I already converted your data JSON format string, this means that response is already a string, should it be returning the response object correctly instead of above line directly return a response object, so is this the same line, yes, but returning a status of 200, by specimen status 200 you explicitly telling flask the response was successful, what did we do, what did we change, that can be reached, it's probably because it's not actually running, need to run the application, still getting the same error, okay it's not happening for us during this stream status 200, should this of the still encountering area might be something outside causing the problem, no I'm pretty sure it was working okay before, what am I doing, using JSON dumps should be okay, still using JSON file, this is quickly ridiculous, this is ridiculous, let's ensure we're not returning numpy array, generate this gdal function returning two objects data points and ecg, we're confident that that points is a list of dictionaries, however ecg might be a numpy array, we are converting this to list using ecg in list, are we, yes, but let's double check that this conversion is successful, the area using typically riser flags makes a response function tries to handle return that it doesn't understand, if response data is genuinely a string, as it should be after using JSON dumps, I feel it should be a string, JSON dumps shouldn't be having this issue, let's focus on the return statement, however since we're using JSON file, we are not using JSON file, it's commented out automatically serializes, try changing the return statement, we're now using, yeah we're not using JSON file, should we be using JSON file, okay let's some comment this, a comment that, a change in return statement to just returning that, so if we do this, we don't need that for this, this eliminates the needs for manually creating response object, okay we got rid of it, still getting the same error though, this doesn't solve the issue, print the types, just before the return, sure everything you expect, right, so before this you can print all the types, type, type, type, clean this for a sec, over 5, what's the output, so I don't see, oops, I don't see, I don't see the print out values of the types, I'm having some serious issues with the whole structure, the thing is all this stuff should be in the generate ECG data, why it's in this root instead, will it pick up on the problem, yes I know what it does, but it needs some serious restructuring, know what the code does, does it need any restructuring, provide a fast way, some improvements, suppression, logic, move the ECG generation and processing logic to a separate module or file, what just happened, it's happening quite a bit today with GPT-4, you know some problem on the server or something, it's generating also, can't stop the microphone from doing speech to text, yeah there is the should be error handling, okay it's not generating what they expect, there's some problem with the shell script, if anyone knows what is it I'm doing, wrong place to let me know, like half a minute, 60 seconds or so, 40 seconds in this stream because we're not going over one hour, the thing is that it used to just work before, GPT actually stuffed it up for me, should be an easy fix and let's clear this last time, generate the error again, yeah now I can turn it off, messages in the chat, please do go check out this site, let me know if you have any comments, it's all open source, so obviously you're not gonna get paid for that, yeah and hopefully after this tool starts to work the ECG feature extraction should come back, so this is what it eventually should look like, but this is not the flask application, so I can't publish this, and unfortunately, okay so it's a numpy array instead of a string problem, yeah but instead of catching exception why not just fix the problem, can start a new chat quickly, okay let's do it, let's do a quick one over time, that's okay, should have another 15 minutes or so, start the new default GPT4, start with index HTML, just so it has some context, we'll ask it as well, to not generate any code, not generate any code, then we do the JavaScript and the Python application at the end, just trying to solve this tiny error, the JSON file is not a text but a numpy array, not generate any code, this is for reference only, we have this Python script, to not generate any code, this is for reference only, forget to turn the microphone off so it will keep writing everything I say, this is probably actually good because I can then tell if I'm talking clearly or not, okay whenever this finishes, when it's closed is run the application again, so we have the error message, this is where the problem starts, oh come on, hitting ctrl c instead of ctrl shift c, in the following error, when running the last application, do I solve it, okay if this doesn't work, I give up, okay this is a good sign, it gave me a solution, comment it down to Jason, right, Jason, Jason, get post, if post, get the values for duration and heart rate, generate ECG data, this will return data in ECG data to least, response data, we've already done this before, in doubts there, keep suggesting doing a Jason dumps return response data, else template HTML, and what's up with all that, we've already done this just before returning the response, return the just as a response, yeah we have import Jason already there, also ensure the generator is still done, returning the proper data can be converted to at least, okay I think that's where the problem is, that didn't help, can we use a different approach, this flask application was working just earlier, I've got to turn off the microphone again, actually can we regenerate this response, so first let's bring back what we had before, because there's nothing wrong with it, okay maybe I went too far, now that's okay we'll keep it there, but let's regenerate this, yeah this should just be good enough, this line here, now ECG and data points that are coming from generate ECG data, okay I kind of give up, yeah we'll try again later, I thought we could publish the application today, probably so I'll see you in a bit, please put your comments, questions, check out bodykills.com, you know what to do.
