Cannot install NumPy from a wheel format
Python 3.xNumpyPython WheelPython 3.x Problem Overview
I am trying to install NumPy from a wheel (.whl) file. I get the error:
> numpy-1.9.1%2Bmkl-cp34-none-win_amd64.whl is not a supported wheel on this platform.
Details:
-
Windows 8.1 pro x64, elevated command prompt
-
Python 3.4.2
-
Package NumPy from Gohlke's site
-
File numpy-1.9.1%2Bmkl-cp34-none-win_amd64.whl copied in the pip.exe folder
The log file shows:
> ------------------------------------------------------------
> d:\Program Files\WinPython-64bit-3.4.2.4\python-3.4.2.amd64\Scripts\pip run on 01/23/15 11:55:21

What is wrong?
Python 3.x Solutions
Solution 1 - Python 3.x
Short answer: rename the file to numpy-1.9.1%2Bmkl-cp34-none-win32.whl to install it.
You can check what tags your pip tool accepts for installation by running:
import pip; print(pip.pep425tags.get_supported())
In this case pip is incorrectly detecting your operating system to be 32-bits and the file you're trying to install was win_amd64 in its filename.
If you rename the file to numpy-1.9.1%2Bmkl-cp34-none-win32.whl (which now contains the tags that are considered supported) then you can install the package. It's a trick because the file is still built for 64-bits but this allows you to install the package as intended.
Solution 2 - Python 3.x
After several tests I think the problem is "win32" or "amd64" itself. I tried replacing those two with "any" and it worked.
Solution 3 - Python 3.x
In my case, the workaround to install gohlke packages on Python (3.4.4 (AMD64)) was to change the "cp34m" part rather than the "win*" parts in previous answers:
python -c "import pip; print(pip.pep425tags.get_supported())":
[('cp34', 'none', 'win_amd64'), ('py3', 'none', 'win_amd64'),
('cp34', 'none', 'any'), ...
ls -ld *:
matplotlib-2.0.0b3-cp34-cp34m-win_amd64.whl
numpy-1.11.1+mkl-cp34-cp34m-win_amd64.whl
pandas-0.18.1-cp34-cp34m-win_amd64.whl
Change the above names to:
matplotlib-2.0.0b3-cp34-none-win_amd64.whl
numpy-1.11.1+mkl-cp34-none-win_amd64.whl
pandas-0.18.1-cp34-none-win_amd64.whl
For example, pip install matplotlib-2.0.0b3-cp34-none-win_amd64.whl
Processing ...
...Successfully installed matplotlib-2.0.0b3
Solution 4 - Python 3.x
To add to the list of other possible solutions, I had to upgrade pip itself. The latest binary from Gholke's site had the "cp27m" tag, which didn't show up when I checked the pip tags using:
import pip; print(pip.pep425tags.get_supported())
After I upgraded pip, the wheel didn't work, but just doing a regular pip install numpy worked.
Solution 5 - Python 3.x
If you have, say, Python 3.4 installed, make sure to install the -cp34- version of the wheel and not -cp35-.
Solution 6 - Python 3.x
The current WinPython package manager need a two-characters fix to accept to recognize the new NumPy + mkl 'wheel'.

Solution 7 - Python 3.x
As a workaround, uninstall the NumPy package:
pip uninstall numpy
Then install it again from cache:
pip install numpy
I had the same problem with several packages after upgrading from 3.4.1 to 3.4.2.
Solution 8 - Python 3.x
Navigate to the directory where your 'pip.py' sits and then type following on the Windows command line:
..\python.exe pip.py install name_of_package.whl
This should work.
Solution 9 - Python 3.x
I had the same problem and tried to work it out with the suggested solutions.
I changed win64 to win32 and it didn't work either. But then I changed the name to original and this time it worked! The only extra thing I did was to go offline. That's so strange.
Solution 10 - Python 3.x
This has nothing to do with your operating system. Uninstall Python 32-bit and install Python 64-bit rather or alternatively find a 32-bit wheel file.
