SSL Error in example Ask A Book Questions

[yamyamyuo]

Hi there, thanks for solving my issue about loading PDF. I came across another issue and suspect it may relate to some python packages version.

I am trying Ask A Book Questions tutorial and get below error when executing this line: docsearch = Pinecone.from_texts([t.page_content for t in texts], embeddings, index_name=index_name)

Appreciate your help in advance!

Haven't seen this one before and I imagine it's on your end w/ your connection. I gotta close this one out because I don't believe it's part of this code. Have you asked gpt4?

[yamyamyuo]

Thanks @gkamradt, it does related to network issue with openAI. It works after correct the network. BTW, do you know how to initiate the pinecone index? Currently I initiate an index with cosine metric, 1536 dimension which indicated by the error message.
