Faiss: Can I save my PCA matrix?

[FeSens]

I've trained a PCA matrix, can I dump it to a file and load it latter?
I'm using python.
Thanks.

Yes, turns out that you can.

PCA = faiss.PCAMatrix(2048,256)
faiss.write_VectorTransform(PCA, "PCA.pca")
PCA2 = faiss.read_VectorTransform("PCA.pca")

I am using python.
Thank you.
