I am trying to call python from Matlab using its python interface. I am first setting the env then calling a simple example but am getting an error:
pyenv('Version', ...
'../bin/python', ...
'ExecutionMode','OutOfProcess')
pyrun("l = ['A','new','list']")
l
Error using feval
Unrecognized function or variable 'py.dict'.
This indicates that something is not setup correctly between Python and MATLAB and is NOT something specific to py.dict.
My test case was wtf = py.list(1:2)
When you are specifying the Python path my understanding is the 3 problems you are most likely to see, if the executable exists, are either:
In python run:
import platform, subprocess
platform.processor()
If it comes back i386 (or not arm) then you are probably using an Intel compiled Python version. For me I had to download a new version of Anaconda Navigator being careful to download the "M1" version (they offer both M1 and Intel and both might install). From there I installed a new environment. This put together a new Python that was using arm.
In MATLAB this is now the line I have in my startup.m file:
pe = pyenv('Version','/opt/anaconda3/envs/sci3/bin/python');
Note sci3 is the name of my environment
../bin/python?
