[Bug] Error creating index in Semantic Search notebook

[jseldess]

Is this a new bug?

• I believe this is a new bug
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

In the Semantic Search notebook, when I try to create the index (code below), I always get an error (see log output) and am not able to proceed with the notebook. In the "Creating an index" step of the semantic search notebook, running:

import time

# only create index if it doesn't exist
if index_name not in pinecone.list_indexes():
    pinecone.create_index(
        name=index_name,
        dimension=len(dataset.documents.iloc[0]['values']),
        metric='cosine'
    )
    # wait a moment for the index to be fully initialized
    time.sleep(1)

# now connect to the index
index = pinecone.GRPCIndex(index_name)

Expected Behavior

I expect the index to be created successfully, so I can proceed with the notebook.

Steps To Reproduce

1. Go to https://colab.research.google.com/github/pinecone-io/examples/blob/master/docs/semantic-search.ipynb.
2. Run through the steps until you get to the create an index code.
3. Run that and you should get the error mentioned above.
