Why does K-Medoids algorithm not work using BetaML.jl package? For example (from docs),

using BetaML

X = [1.1 10.1; 0.9 9.8; 10.0 1.1; 12.1 0.8; 0.8 9.8]
mod = KMedoidsClusterer(n_classes=2)

#Throws error: KMedoidsClusterer not defined

Am I using the wrong function? Thanks.

This works for me. What is your package status? In case you haven’t done it before, you can get this with

] st

at the REPL. I have BetaML v0.9.5, so if yours is outdated it might not have this functionality.

Surprisingly, when I add the package to my global environment, it adds the 0.7.0 version. Not sure what’s the reason for this. Here is the list of packages I have installed. Can you point out if this is due to some dependency conflict?

Try doing ] add BetaML@0.9.5. This probably won’t get the issue fixed, but should give a message indicating the package(s) that may be blocking the update.

From there, you can remove the packages that are causing issues and try again. Usually this happens with old packages that are no longer maintained.
