Ask a Book Questions - errors in Pinecone integration

The notebook is out of sync with the current version of Pinecone. Here are some thoughts:

• from langchain.vectorstores import Chroma, Pinecone: I think it's better to install langchain_pinecone and use from langchain_pinecone import PineconeVectorStore: https://python.langchain.com/docs/integrations/vectorstores/pinecone
• Using the latest Pinecone client installed by pip install pinecone-client, you'll need to change import pinecone to from pinecone import Pinecone. When creating an index, you'll also need to import the ServerlessSpec or PodSpec class.
• With an up-to-date client, initialization is a little different and doesn't include environment. Instead of:

  pinecone.init(
   api_key=PINECONE_API_KEY,  # find at app.pinecone.io
   environment=PINECONE_API_ENV  # next to api key in console
  )

  you use:

  pc = Pinecone(api_key=PINECONE_API_KEY)

• Also, the notebook seems to assume a Pinecone index already exists. If you want to point people at guidance on creating indexes, you could use https://docs.pinecone.io/docs/manage-indexes#create-a-serverless-index.
