Here is scikit-learn stable:
https://github.com/scikit-learn/scikit-learn/tree/master/sklearn/linear_model
Notice how in 0.21.x _logistic.py
doesn't exist. On your working development environment do:python3 -m pip freeze > requirements.txt
try this version :
pip3 install "scikit_learn==0.22.2.post1"
