----
first, (optional but I'd reccommend to) disinstall numpy using the same
pip script that you used to install it, something like
$ pip uninstall numpy # possibly using sudo
----
next, you must be sure that Python 3.6 has pip, either
$ /path/to/python3.6 -m ensurepip --user
or (if you are installing in a virtual environment)
$ /path/to/python3.6 -m ensurepip
the above is going to install pip if it is not already present in the
environment of Python 3.6 --- please see
https://docs.python.org/3/library/ensurepip.html
for the gory details
----
finally, install numpy for 3.6
$ /path/to/python3.6 -m pip install --user numpy
----
The command "/path/to/python3.6 -m modulename ..." ensures that the
module and the Python version are matching one with the other.
