Visual C++ 10.0 Issue When Installing Python Module; Cl.exe Failed With Exit Status 2 (h5py)

I've been at this for the last 5 hours or so. I've reinstalled a bunch, but essentially I'm trying to install the Python module h5py on a Windows 8.1 machine running Python 3.4.1.

Solution 1:

OK! So I did it.

Here's how:

1. I uninstalled all Python versions and deleted all Python-related files, folders, etc. (included PATH variables and packages).
2. I uninstalled all Microsoft Visual Studio C++ 2010 Redistributable, Microsoft Windows SDK for Windows 7, and .NET Framework 4 programs (BE CAREFUL WITH THIS. If you just do the correct files, then you will be fine. I uninstalled other Microsoft programs and ran into several registry errors...).
3. Reinstall Microsoft Windows SDK for Windows 7 and .NET Framework 4.
4. Reinstall Microsoft Visual C++ 2010 Redistributable Package (x64).
5. Reinstall Microsoft Visual C++ 2010 Service Pack 1 Compiler Update for the Windows SDK 7.1.
6. Reinstall Python 3.4.0 (to C:\Python34).
7. Add C:\Python34 and C:\Python34\Scripts to the PATH system variable.
8. Download H5py from this website here (specifically h5py-2.6.0-cp34-cp34m-win_amd64.whl).
9. Run pip3 install h5py-2.6.0-cp34-cp34m-win_amd64.whl. This will generate the following:

Processing c:\python34\h5py-2.6.0-cp34-cp34m-win_amd64.whl Collecting numpy>=1.6.1 (from h5py==2.6.0) Downloading numpy-1.11.1-cp34-none-win_amd64.whl (7.4MB) 100% |################################| 7.4MB 46kB/s Collecting six (from h5py==2.6.0) Using cached six-1.10.0-py2.py3-none-any.whl Installing collected packages: numpy, six, h5py Successfully installed h5py-2.6.0 numpy-1.11.1 six-1.10.0

Next I ran my program to make sure the import worked correctly, and it did! I hope this helps anyone trying this, just be VERY careful with step (2).

Solution 2:

I had the same problem trying to install from the command prompt on my Windows 10 machine. To bypass this error:

1. I manually downloaded the application from website
2. Extracted it to my C:/"Path where you want to setup the application"
3. Went back into command prompt open up the path where you just extracted the application
4. Run the setup file in the downloaded package from there.

It worked me!!!
