Cannot import spherecluster with scikit-learn 1.0.2: sklearn.cluster.k_means_ has been renamed

The traceback is

ModuleNotFoundError: No module named 'sklearn.cluster.k_means'

The problem is that 'sklearn.cluster.k_means_' has been renamed to 'sklearn.cluster._kmeans' in some intermediate scikit-learn version.

Hi !

I haven't tested it with the most recent version of scikit but I solved this issue for scikit 0.24 in my pull request #34 (you can also check my fork) where the change from sklearn.cluster.k_means_ to sklearn.cluster._kmeans appeared.

From what I remember it was a bit more complicated than a simple renaming issue because some functions called by sklearn.cluster.k_means_ are now class methods of KMeans.

Hope this helps !

@rfayat Hey, I tried your version, but ran into

from sklearn.cluster import _k_means_fast as _k_means

ImportError: cannot import name '_k_means_fast' from 'sklearn.cluster'

Does it mean that interfaces changed once again or I'm just using a wrong version?

[rfayat]

Hey @Darel13712 indeed I just checked and it seems to have changed again between v0.24 and V1.0.2, my fork won't work for this newest version...

Sorry for the false hope 😞

Cheers,

RF
