Pip, Python Wheels and Numpy compilation Issues

I was using numpy with the MKL compilation however when developing a GUI program i hit the following OMP warning when numpy 1.9.2+MKL is packaged with py2exe

Therefore I need to use the non-mkl numpy version, so I added the second wheel to my wheelhouse.

numpy-1.9.2+mkl-cp27-none-win32.whl
numpy-1.9.2-cp27-none-win32.whl

in my requirements file, I can state the following

numpy==1.9.2

Then pip installs one of the above wheels .

Is there a way to tell pip which of the above numpy versions that I want to install from the above list ? I cannot find a generic way to do this ?

Solution

  • You can add the used BLAS library name to the local version identifier like

    numpy-1.9.2+mkl-cp27-none-win32.whl
numpy-1.9.2+atlas-cp27-none-win32.whl

    and then specify the version like

    numpy==1.9.2+atlas
