I successfully uploaded the pdf to pinecone according to your guidance, but when I ran it, I reported an error: Failed to initialize Pinecone Client

It should not be a problem with my python implementation. It would never stop the start of gpt4-pdf-charbot-langchain project. Both projects are seperated and you should not mix them. To me it looks like an issue with your setup of gpt4-pdf-chatbot-langchain. Check out my detailed walkthrough and see if you spot some issues. Reinstalling the application also can help a lot.

[Ethan2Perth]

I re-installed according to your instructions https://github.com/ucl98/gpt4_langchain_pdf-detailed-walktrough, and I can't connect to pinecone as before. Can you help me see what is wrong? Thanks.

PS E:\gpt4-pdf-chatbot-langchain-main_2\gpt4-pdf-chatbot-langchain-main> npm run ingest

Node.js v20.1.0

[ucl98]

Why dont you use my python code for ingest? It is a seperat project and should not be mix with the original project. You can simply ingest your pdfs with my python code and the sources will appear in the chatbot. You would not have to deal witht he pinecone issues. Nodejs is in general more prone for errors and not so easy to set up. As long as “npm run dev” works, you can start the chatbot.

[Ethan2Perth]

Sorry, I didn't express what I mean clearly. I have successfully run your 'loading.py' yesterday, but I got an error when chatting with the chatbot. This error has been bothering me. I sincerely hope that you can help me solve this problem.

[ucl98]

Glad to see that the vectors could be initialized 😃
There are others with the same problem: mayooear/ai-pdf-chatbot-langchain#226.
Since the error message doesn't tell much it is hard to determine what went wrong. I cannot help there besides telling you to double check everything.

[0rangeAppl3]

I also got the same issue

Wonder if anyone know how to solve it

[zinxor]

Running into the same issue as well.

On the frontend seeing an error response as:
error SyntaxError: Unexpected token '<', "<!DOCTYPE "... is not valid JSON

[ucl98]

You have an issue with your Pinecone API key.

Error: Unauthorized - API key is missing or invalid
