After opening up an issue with the SciPy team, we found that you need to upgrade pip with:
pip install --upgrade pip
And in Python 3
this works:
python3 -m pip install --upgrade pip
for SciPy to install properly. Why? Because:
Older versions of pip have to be told to use wheels, IIRC with –use-wheel. Or you can upgrade pip itself, then it should pick up the wheels.
Upgrading pip solves the issue, but you might be able to just use the --use-wheel
flag as well.
