Cannot access Python using PythonEnvironment

6 次查看(过去 30 天)
I am unable to get a PythonEnvironment to work
>> pyenv('Version', '/Users/bendichter/opt/miniconda3/bin/python')
ans =
PythonEnvironment with properties:
Version: "3.9"
Executable: "/Users/bendichter/opt/miniconda3/bin/python"
Library: "/Users/bendichter/opt/miniconda3/lib/libpython3.9.dylib"
Home: "/Users/bendichter/opt/miniconda3"
Status: NotLoaded
ExecutionMode: InProcess
>> py.math.sqrt(42)
Unable to resolve the name 'py.math.sqrt'.
>> py.list({'a','b'});
Unable to resolve the name 'py.list'.
I have tried a few different versions of Python in various conda environments. I am using coda and an M1 mac. The print out of pyenv seems to indicate that the python installation is registered correctly, but none of the subsequent commands that use the Python connection work.

Hi, I had the same problem, and fixed it.
For M1 mac, we can install intel and arm versions of python.
When I installed the arm version, the problem occured. When I installed the Intel version, the problem did not occurred.
I hope this can be helpful for you.

Hello Ben,
I understand that you are facing difficulties while using the MATLAB Python co-execution feature and encountering errors while executing the Python commands.
You can follow the below steps to resolve the issue:
  1. MATLAB automatically loads Python when you type "py.command". You cannot change the interpreter after MATLAB loads Python. To change the interpreter, restart MATLAB.
  2. After restarting, check that MATLAB is using the desired Python environment. You can do this by running the "pyenv" command in MATLAB.
You can refer to the below documentation to understand more about "pyenv" in MATLAB.
