How to install in python 3.4 -.whl files

Question

I recently tried reinstalling numpy for python 3.4 since I got a new computer and I'm afraid. I am on windows 8.1, and from what I remember, I previously used the .exe file, which did everything for me. However, this time I was given a .whl file (apparently this is a "Wheel" file), which I cannot figure out how to install.

Other posts explained that I should use PIP, however the explanations of how to install these files that I could find are terrible. The command "python install pip" or "pip install numpy" or all the other various commands that I saw return only the error "python is not recognized as an internal or external command, operating program or batch file", or "pip is not recognized as internal .. .. ".

I also tried "python3.4", "python.exe" and many others, since it does not like python. The file name of the numpy file I uploaded is "numpy-1.9.2 + mkl-cp34-none-win_amd64.whl".

So can anyone give me a detailed tutorial on how to use them, as well as views on the things that all modules use now. Also, why did people stop using .exe files to install them? It was a lot easier!

Answer 1

Python 3.4 comes with PIP already included in the package, so you can start using PIP right after installing Python 3.4. Commands like pip install <packagename> only work if the PIP path is included in the path environment variable. If this is not the case and you do not want to edit the environment variables, you need to provide the full path. The default PIP location in Python 3.4 is in C:\Python34\Scripts\pip3.4.exe . If this file exists (it should), enter the command C:\Python34\Scripts\pip3.4.exe install <numpy_whl_path> , where <numpy_whl_path> is the full path to your numpy.whl file. For example: C:\Python34\Scripts\pip3.4.exe install C:\Users\mwinfield\Downloads\numpy‑1.9.2+mkl‑cp34‑none‑win_amd64.whl .

See the simplest solution is to unzip the .whl file using 7-zip. Then in the unpacked directory you will find a module that you can copy and paste into the C:/Python34/Lib/site-packages/ directory (or wherever you install Python).
