How can I fill an empty pyversion library?

I am attempting to call Python2.7 using MatLab. However, I continue to get the following error.

I have followed the problem solving page linked below. The first three checks seemed to be okay, but I cannot check if the Python Module is on the Python Search Path because I cannot call anything using "py.___"

When I run pyversion, I think I see the problem. The output of pyversion is below:

Everything looks good except the library is empty. The few examples I have seen have show an wide variety in what should be in the library. (Examples have been linked below)

I am running Windows10 and using 64-bit MatLab and Python. MATLAB Version: 9.2.0.556344 (R2017a)

Hi Matthew

I had the same problem. In my case, the problem was that the python version was not within the system path in Windows. I solved the problem by adding the installation path of python (in your case C:\Python27) to the Path variable.

You must have a version of Python that is compatible with MATLAB. Currently, MATLAB supports versions 2.7, 3.6, 3.7, and 3.8. For more info, copy and past the following into your MATLAB comand window.
