I am working on a project for my Computer Class wherein we were instructed to follow a particular (YouTube Video). I have followed the video in its entirety but I’ve been encountering a few errors, some of which I was able to change. My current code looks like: (I have listed my problems underneath)

Pictures of how the current application looks:

My Application

The versions of the APIs and Python are:

1. openai 1.35.3
2. Python 3.12.4
3. Name: PyQt5, Version: 5.15.10, License: GPL v3, Requires: PyQt5-Qt5, PyQt5-sip
4. I use VS-Code

Note: I used ****, ***** in the Image address just here for privacy, on VS-Code its the real thing.

The problems I had faced include:
1.QPixmap::scaled: Pixmap is a null pixmap:(Now Corrected)
2. No attribute KeepAspectRatio in Qt:(Now Corrected)
3. Input label, Input field, Answer Label, Answer Field, Submit Button, etc. not showing up in the layout after running.
4. OpenAI’s API returns an error: openai.RateLimitError: Error code: 429 - {'error': {'message': 'You exceeded your current quota, please check your plan and billing details. For more information on this error, read the docs: https://platform.openai.com/docs/guides/error-codes/api-errors.', 'type': 'insufficient_quota', 'param': None, 'code': 'insufficient_quota'}}

What I’ve tried/Corrected:
Problems 1&2:

1. The Pixmap Null error has been removed: I found that my version of PyQt5 has somethings moved around, so the KeepAspectRatio now comes under AspectRatioMode, and SmoothTransformation comes under TransformationMode. I’ve corrected them and you shall see the corrected code in my code display.
2. Similarly I figured that the PixMap returned null because there was a mistake in the path of the image file which has also been corrected.

Problem 3: Haven’t been able to get this working

Problem 4: When I change the current code like: self.submit_button = QPushButton('Submit') to self.submit_button = QPushButton('Submit',self) then the submit button shows but upon clicking any of the “popular questions” the program stops responding and raises an error after closing the error is: raise self._make_status_error_from_response(err.response) from None openai.RateLimitError: Error code: 429 - {'error': {'message': 'You exceeded your current quota, please check your plan and billing details. For more information on this error, read the docs: https://platform.openai.com/docs/guides/error-codes/api-errors.', 'type': 'insufficient_quota', 'param': None, 'code': 'insufficient_quota'}}

Please help me understand where the code seems to go wrong and what I could do to make the fixes, thankyou so much for your effort and time. I would appreciate if you could also direct me to some resources which could help me, being a beginner looking through the documentation seems very daunting and overwhelming – something I hope to overcome soon 🙂
