First of all, thank you for the great project! I get the error: module 'faiss' has no attribute 'swigfaiss' when running the following command:

import autofaiss

autofaiss.build_index(
    "embeddings.npy",
    "autofaiss.index",
    "autofaiss.json",
    metric_type="ip",
    should_be_memory_mappable=True,
    make_direct_map=True)

The error appears when running it for make_direct_map=True.

Tested using conda 4.11.0 or mamba 0.15.3 using pytorch or conda-forge channel.

I had the exact same issue. Turns out it was due to both faiss-cpu and faiss-gpu being installed.

With faiss-cpu 1.7.3 (installed via pypi) this issue comes up again and can be reproduced with e.g.

embeddings = np.float32(np.random.rand(100, 512))
build_index(embeddings, make_direct_map=True, save_on_disk=False)

AttributeError: module ‘faiss’ has no attribute ‘swigfaiss’

With faiss-cpu 1.7.2 installed it works as expected.
