Is a Fuzzy C-Means algorithm available for Python?
I have some dots in a 3 dimensional space and would like to cluster them. I know Pythons module "cluster", but it has only K-Means. Do you know a module which has FCM (Fuzzy C-Means)?
(If you know some other python modules which are related to…

fuzzy-c-means - setting initial number of clusters=6, but only 4 cluster labels generated
I use the fuzzy-c-means clustering implementation and I would like the data X to form the number of clusters i define in the algorithm(I beleive that is how it works). But the behavior is confusing.
cm = FCM(n_clusters=6)
cm.fit(X)
This code…
