Install OpenEXR for python with pip on Windows

Question

I am trying to install OpenEXR module for python using pip.

C:\Python27_64\Scripts\pip.exe install openexr

But I get the following error:

Before getting this error I was asked to install Microsoft Visual C++ Compiler for Python 2.7. So I did, and that fixed the first error but I still have the error I'm showing you.

Could you eventually make this work? If so, maybe you can tell us what you did [here](https://github.com/jamesbowman/openexrpython/issues/4). — Amir, Mar 21 '18 at 18:20
I couldn't install from pip. I ended up downloading it from this page: http://www.lfd.uci.edu/~gohlke/pythonlibs/ — tuket, Mar 21 '18 at 23:27
Late, but can be helpful (Using Anaconda): conda install -c conda-forge openexr-python — saveearth, Apr 08 '21 at 15:38

One option is to use Anaconda:

conda install -c conda-forge openexr-python
