ValueError: source code string cannot contain null bytes while import sklearn

Question

I'm trying to import MinMaxScaler from sklearn.preprocessing. when I run my code this error appears that refers to the import line:

ValueError: source code string cannot contain null bytes.

I checked and updated all of the requirements for scikit-learn and the error still appears. I also tried to open a blank python file with only this line :

from sklearn.preprocessing import MinMaxScaler

but it didn't help.

What can I do?

*I'm using windows 10.

Answer 1

I had the same error (with numpy module) and it was caused by a power outtage. the requirements.txt instalation with pip was interrupted resulting in a corrupted module.

I went manually to the site-packages folders, deleted numpy and installed it again using pip install numpy

After that problem was solved. Hope this helps!
