Import error: No module named 'scipy._lib'

Question

I'm using pythonanywere.com to deploy my Django application. So I've installed a few machine learning libraries to that virtual environment.

(venv) 19:16 ~ $ pip3 list
Package         Version

sklearn         0.0               
wheel           0.31.1 

But when I tried to python3 manage.py runserver I got this

    from sklearn.linear_model import SGDClassifier
  File "/home/kirillkorolev/.virtualenvs/venv/lib/python3.6/site-packages/sklearn/__init__.py", line 134, in <module>
    from .base import clone
  File "/home/kirillkorolev/.virtualenvs/venv/lib/python3.6/site-packages/sklearn/base.py", line 11, in <module>
    from scipy import sparse
  File "/home/kirillkorolev/.virtualenvs/venv/lib/python3.6/site-packages/scipy/__init__.py", line 110, in <module>
    from scipy._lib._version import NumpyVersion as _NumpyVersion
ModuleNotFoundError: No module named 'scipy._lib'

Previously I did the same thing on a local machine and it worked fine.

Tested in a console on pythonanywere.com under Ubuntu 14.04.5 LTS

Answer 1

This is just an update. I also faced same error. Solution of this issue is installation of below package. sudo apt install --reinstall python*-decorator

Answer 2

This seemed to resolve itself for me just by running:

 pip uninstall scipy &&  pip install scipy

Even though I had the latest version of scipy (1.4.1)
