Cannot uninstall Numpy 1.8.2

[normanhh3]

When building on Docker for Mac I ran into the following issue.

Requirement already satisfied: setuptools in /usr/local/lib/python2.7/dist-packages (from kiwisolver>=1.0.1->matplotlib) (39.1.0)
Building wheels for collected packages: Theano, bandmat, subprocess32
  Running setup.py bdist_wheel for Theano: started

Successfully built Theano bandmat subprocess32
Installing collected packages: numpy, scipy, six, Theano, lxml, cycler, kiwisolver, python-dateutil, pytz, subprocess32, backports.functools-lru-cache, pyparsing, matplotlib, bandmat
  Found existing installation: numpy 1.8.2
Cannot uninstall 'numpy'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
The command '/bin/sh -c pip install Theano lxml matplotlib bandmat' returned a non-zero code: 1

here's what helped me to make it work: RUN pip install --ignore-installed six Theano lxml pyparsing matplotlib bandmat
