MHKiT-Matlab Python recognition issues #46

Closed t-osu closed 3 years ago

t-osu commented 3 years ago

I successfully installed python,pycharm,mhkit,and the related packages and ran the example river code from the installation page with no issues. However I am having quite a bit of trouble with matlab recognizing mhkit. Using gitbash I cloned MHKiT-MATLAB, put it in my Matlab path, and then navigated to that folder in my windows terminal and ran pip install -e . As per instructions. In matlab I ran pyversion and read out what the installation page notes. I double checked the place executable, library, and home were going to and they are correct. Finally I double clicked mhkit.mltbx and installed it with a note telling me that it got installed and was enabled. Unfortunately, when I try the test code from the installation page, I get multiple different errors.

I have repeated the Python and Matlab installation multiple times to make sure I didn't overlook anything, yet this didn't help. Any ideas?

Hi Chris,

Did you install MHKiT-Python with a pip install or by cloning the repo? Can you also provide the print out from typing "pip list" in a terminal window? It looks like there is an issue with one of the python packages MHKiT uses.

@t-osu Matlab does not support Python 3.9 see https://www.mathworks.com/content/dam/mathworks/mathworks-dot-com/support/sysreq/files/python-compatibility.pdf

I am getting the same error in python 3.8. I am going to close this issue. Please follow/ watch what Rebecca and I do to solve this issue on #49 and let us know if what we come up with does not solve your issue as well.
