Faiss library error

[apal6]

Hi,

I have been trying to use treeArches for my analysis. I had a hard time getting the setup done but finally everything worked. I now have been having issues when I tired to run the following code:

>>> import faiss
>>> import pickle
>>> file_to_read = open("/scratch/users/apal6/treeArches/tree_HLCA_FAISS.pickle", "rb")
>>> HLCA_tree = pickle.load(file_to_read)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'faiss.swigfaiss_avx2'
>>> 

Not sure what is happening but here are the version of faiss library:
faiss-gpu==1.7.2

Any suggestion?

Thank you so much!
