Problem

When using an outdated version of LangChain, you may encounter errors like the following: 
Pinecone has no attribute 'from_texts'

Pinecone has no attribute `from_documents'

​
Solution

Previously, the Python classes for both LangChain and Pinecone had objects named Pinecone, but this is no longer an issue in the latest LangChain version. To resolve these errors, upgrade LangChain to >=0.0.3: 
pip install --upgrade langchain-pinecone
Depending on which version of LangChain you are upgrading from, you may need to update your code. You can find more information about using LangChain with Pinecone in our documentation.
