langchain.vectorstores has been deprecated.

To update/intall the packages run the following command in terminal

%pip install --upgrade --quiet  langchain-pinecone langchain-openai langchain

Update your code like this:

import os
os.environ["OPENAI_API_KEY"] = "api-key"
os.environ["PINECONE_API_KEY"] = "pinecone-key"

from langchain.text_splitter import CharacterTextSplitter
from langchain_community.document_loaders import PyPDFLoader
from langchain_openai import OpenAIEmbeddings

loader = PyPDFLoader("beyond-good-and-evil.pdf")
documents = loader.load()
text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
docs = text_splitter.split_documents(documents)
# print(docs)

embeddings = OpenAIEmbeddings()

from langchain_pinecone import PineconeVectorStore

index_name = "companion"

docsearch = PineconeVectorStore.from_documents(docs, embeddings, index_name=index_name)

query = "What is the meaning life??"
docs = docsearch.similarity_search(query)
print(docs[0].page_content)
