Is there a persistence function [python]?

Hi everyone

whether there is a way to save cluster/index into a local file?

For example:

ncentroids = 1024
niter = 20
verbose = true
d = x.shape[1]
kmeans = faiss.Kmeans(d, ncentroids, niter, verbose)
kmeans.train (x)

after kmeans.train(x), I want to save the result into a local file, then next time I only need to load the file, and search cluster as follows (instead of re-run the clustering on the original data)

D, I = kmeans.index.search(x, 1)

Hi,

You can save index to a file with write_index and load it with read_index, see
