No module named Sklearn

BrianChan — Tue, 21 Apr 2026 07:16:50 GMT

Hi all, I am practicing the feature in CDSW.

When trying to do an experiment, I got an error in the session as below:

-------error-------

import pickle

import cdsw

model = pickle.load(open('model.pkl', 'rb'))

ModuleNotFoundError: No module named 'sklearn'

ModuleNotFoundError Traceback (most recent call last)
/tmp/ipykernel_115/2912545845.py in <module>
----> 1 model = pickle.load(open('model.pkl', 'rb'))

ModuleNotFoundError: No module named 'sklearn'

Engine exited with status 1.

-------error-------

However, in the Build session in Experiment, I see Sklearn is installed in the docker container.

Therefore, I have no idea why it fails. Could someone point out the reason for me please? Thank you.

I managed to fix the issue.

As I am using CDSW template, the library install be default is "sklearn". The correct library name should be "scikit-learn".
