How to resolve the error when generating charts after the frontend uploads a PDF file?

[miyuan12345]

I keep getting errors while generating charts, whether I pass a PDF file or a TXT file (attached image). Is there any way to solve this problem?

Hi @miyuan12345 it is working at our end can you try on deployed version also share which specific llm you choose for extraction

I followed your video on Bilibili and didn't make any changes, so I'm not sure which specific LLM I chose for extraction. I also don't know where my code went wrong, but when deploying the environment and processing the requirements.txt file, I encountered many errors. I'm not sure if I made a mistake while handling the errors. Below is my requirements.txt file, and I'm using Python 3.9. Could you help me take a look? Thank you very much.
