Hi everyone,
I’ve been stuck on trying to run some matlab-python code for a week now and nothing seems to work. I am trying to run the following code: https://github.com/fooof-tools/fooof_mat?tab=readme-ov-file which requires python to be compatible with MATLAB. I’ve read so many things but nothing has worked so far. This is my first time trying to code in python-matlab simultaneously so the answer might be something simple that I am just not aware of.
What has worked so far:
I created a new environment called ‘env’ which is located in location ‘fri_test’. In this environment I have installed fooof, matlibplot, pandas.
Then, I open a fresh MATLAB window and type in the following:
pyenv
This is the output:
ans =

PythonEnvironment with properties:

Version: "3.9"
Executable: "/Users/c1034944/fri_test/env/bin/python"
Library: "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/libpython3.9.dylib"
Home: "/Users/c1034944/fri_test/env"
Status: NotLoaded
ExecutionMode: InProcess
I then run:
python_env_path = ‘/Users/c1034944/fri_test/env/bin/python’
pyenv("Version",python_env_path);
py.list({‘This’,’is a’,’list’})
output:
ans =

Python list with no properties.

[‘This’, ‘is a’, ‘list’]
Lastly, run this again to check the python environment:
pyenv
output:
ans =

PythonEnvironment with properties:

Home: "/Users/c1034944/fri_test/env"
Status: Loaded
ExecutionMode: InProcess
ProcessID: "42704"
ProcessName: "MATLAB"

As you can see the ‘executable’ is finding the correct location of the environment I created in fri_test. The ‘ExecutionMode’ has also now updated to ‘InProcess’. However, the ‘Library" is still calling the python version from the Library/Developer.
To test if numpy is working, I run the following:
freq=([0 0.9766 1.9531 2.9297])
py.numpy.array(freq)
this is the error message:
Unable to resolve the name py.numpy.array.

More info: The ‘fooof’ code I am trying to run contains the following line: py.numpy.array(freqs), where ‘freqs’ is a list of 1 x 257 numbers. To my understanding py.numpy.array(freqs) converts the matlab (.mat) file ‘freqs’ into a python-compatible array.
Conclusion: I have no idea what is the issue here and why numpy is not working. I know that MATLAB and python versions are compatible, but maybe I am making a different mistake. I am hoping that finding a solution to numpy problem and that may fix the whole issue – is there any other way to convert .mat files into python arrays?
Any suggestions would be helpful!
