install numpy on python 3.5 Mac OS High sierra
If running pip3.5 --version or pip3 --version works, what is the output when you run pip3 freeze? If there is no output, it indicates that there are no packages installed for the Python 3 environment and you should be able to install numpy with pip3 install numpy.
I wanted to install the numpy package for python 3.5 on my Mac OS High Sierra, but I can't seem to make it work.
I have it on python2.7, but I would also like to install it for the next versions. 
Currently, I have installed python 2.7, python 3.5, and python 3.7.
I tried to install numpy using:

brew install numpy --with-python3 (no error)
sudo port install py35-numpy@1.15.4 (no error)
sudo port install py37-numpy@1.15.4 (no error)
pip3.5  install numpy (gives "Could not find a version that satisfies the requirement numpy (from versions: )
No matching distribution found for numpy" )

I can tell that it is not installed because when I type python3 and then import numpy as np gives "ModuleNotFoundError: No module named 'numpy'"
Any ideas on how to make it work?
Thanks in advance.
