ModuleNotFoundError: No module named 'haystack.document_store.faiss'; 'haystack.document_store' is not a package

Question I am trying to use haystack FAISS and other libraries in Haystack. Previously successfully I installed all requirements following your installation guild in my old deep learning GCP VM. But I needed to se up new deep learning VM and I did creat a new python environment with python 3.7, 3.10 none of them are satisfying requirements in your haystack package . When installing haystack it showing me the following error each and every time now and I can’t continue to my rest of code. I did even downgrade my torch version to 10 to satisfy requirements but still not be able to pass this. Could you please advise how to resolve. This is very urgent case for me.

Cheers Shabnam
