Calling Python from Matlab / Can I use Python installed by Anaconda? / "NULL pointer returned from Python."
显示 更早的评论
Would love to use some Python code a colleague wrote. I already have Anaconda installed, so I really don't want to install another version of Python (and associated libraries).
Tried:
pe = ...
pyenv('Version',...
fullfile('e:\', 'anaconda3', 'python.exe'));
myPythonVersion = pe.Version
py.print("Hello, Python!")
Got:
>> pe = ...
pyenv('Version',...
fullfile('e:\', 'anaconda3', 'python.exe'));
myPythonVersion = pe.Version
py.print("Hello, Python!")
myPythonVersion =
"3.8"
NULL pointer returned from Python.
>> py
>> pe
pe =
PythonEnvironment with properties:
Version: "3.8"
Executable: "e:\anaconda3\python.exe"
Library: "e:\anaconda3\python38.dll"
Home: "e:\anaconda3"
Status: NotLoaded
ExecutionMode: OutOfProcess

Matlab Version R2020a (happy to upgrade, just too lazy right now...)

Try this start-up sequence: first open an Anaconda Prompt or Anaconda PowerShell terminal. Then within that terminal window, type the path to the matlab executable (or is it a launch .bat file on Windows?). Or just type 'matlab' if it is in your system-wide search path.
Then within matlab just do
>> pyenv
with no arguments to see if matlab figured everything out on its own.

This worked fine for me too. When anaconda launches Matlab, it directs it to a pathfile which has pyhton libraries in anaconda.
