sklearn_extra installation issue

Question

[in]:

from sklearn_extra.cluster import KMedoids

[out]:

ModuleNotFoundError: No module named 'sklearn_extra'

Then, I tried installing sklearn_extra via

[in]:

python -m pip install sklearn_extra

[out]:

ERROR: Could not find a version that satisfies the requirement sklearn_extra (from versions: none)
ERROR: No matching distribution found for sklearn_extra

Then, I went to installation part of the website(https://scikit-learn-extra.readthedocs.io/en/latest/install.html) and did what it said:

Installation
Dependencies
scikit-learn-extra requires,

Python (>=3.5)

User installation

[in]:

pip install https://github.com/scikit-learn-contrib/scikit-learn-extra/archive/master.zip

[out]:

      class RegexFlag(enum.IntFlag):
  AttributeError: module 'enum' has no attribute 'IntFlag'

I checked versions of Cython,Python and sklearn they satisfy the required range.

Edit: the solution is to uninstall enum34 for me thanks to Balraj Ashwatt's comment.

pip uninstall -y enum34

Then I was able to install sklearn_extra

Answer 1

I tried,

pip install scikit-learn-extra
