installing SciPy with PyPy on Windows

Question

I am trying to install SciPy with PyPy on Windows. I installed PyPy with the windows 32-bit zip on the website. I installed numpy using python setup.py install . I tried to install scipy with pip install scipy or related commands, I always get a "NotFoundError: no lapack/blas resources found" error. Note I cannot install with wheels because they are meant for CPython 2.7 not PyPy 2.7

How can I solve this problem, especially since most of SciPy is compatible with PyPy?

Answer 1

As the error message says, you'll need to install a BLAS+LAPACK library.

The build instructions for Scipy on CPython https://scipy.github.io/devdocs/building/windows.html probably are applicable here, but precisely what you need to do depends on what compiler you used for Pypy.
