filename.whl is not supported wheel on this platform

Question

I would like to install scipy-0.15.1-cp33-none-win_amd64.whl that I have saved to the local drive. I am using:

pip 6.0.8 from C:\Python27\Lib\site-packages python 2.7.9 (default, Dec 10 2014, 12:28:03) [MSC v.1500 64 bit (AMD64)] 

When I run:

pip install scipy-0.15.1-cp33-none-win_amd64.whl 

I get the following error:

scipy-0.15.1-cp33-none-win_amd64.whl is not a supported wheel on this platform

What is the problem?

Answer 1

cp33 means CPython 3.3.

You need scipy‑0.15.1‑cp27‑none‑win_amd64.whl instead.

Answer 2

This can also be caused by using an out-of-date pip with a recent wheel file.

I was very confused, because I was installing numpy-1.10.4+mkl-cp27-cp27m-win_amd64.whl (from here), and it is definitely the correct version for my Python installation (Windows 64-bit Python 2.7.11). I got the "not supported wheel on this platform" error.

Upgrading pip with python -m pip install --upgrade pip solved it.
