importing voyageai leads to "type error"

[rojas70]

Greetings,

I am running anthropic-cookbook on Linux Ubuntu 20.04.
I am running the skills/classification guide:
https://github.com/anthropics/anthropic-cookbook/blob/main/skills/classification/guide.ipynb

I can run cells find until RAG augmentation, where I import voyageai:

import voyageai

I get the following error:

---------------------------------------------------------------------------

TypeError: 'ABCMeta' object is not subscriptable

Note that I do have a voyageai key (though one should not be needed to import the module I believe). The key has been set in my .bashrc file via:
export VOYAGE_API_KEY='XXXXX'.

Please advice on how to proceed.

This happened since I was using python3.8. It was solved with python3.9.
