Answer by Colonel Panic for How can I install NumPy on Windows using 'pip install'?

Frustratingly, the NumPy package published to PyPI won't install on most Windows computers: Windows wheel package (.whl) on Pypi #5479

Instead:

1. Download the NumPy wheel for your Python version from Archived: Unofficial Windows Binaries for Python Extension Packages, NumPy

2. Install it from the command line:

   pip install numpy-1.10.2+mkl-cp35-none-win_amd64.whl
