Hi, I am creating index in Pinecone from documents and I get this message:

Nothing from PyTorch, TensorFlow >= 2.0, or Flax has been found. Models will not be available and only tokenizers, configuration, and file/data utilities can be used.

What can it be?

Hi, I'm trying to customise "doc_id" as it is in the documentation but I'm getting an error.

What can I have wrong?

Thanks
