B.I., thank you, but your recipe did not work for me:

      Note: if you need reliable uninstall behavior, then install
      with pip instead of using `setup.py install`:

        - `pip install .`       (from a git repo or downloaded source
                                 release)
        - `pip install numpy`   (last NumPy release on PyPi)
