2 versions of module installed, how to import the earlier one

[Larz60+]

pip install --force-reinstall numpy==1.15.4
will replace current version. Careful, other version will be gone when done!

Be aware, that based on your comments, it looks like you have more than one version of python installed.
check version with:

python -V
# then make sure pip matches python
pip -V
# finally pip list to show versions of software installed
