Deployed MATLAB Application not able to detect Python

I have coded a MATLAB application which uses Python. When executing as code, there are no issues and the code is working fine.

But when the same application is deployed as an exe and executed, the application is unable to detect the Python distribution and error is returned.

I am getting the following warning and error

警告: Python コマンドには、サポートされているバージョンの CPython が必要です。「<a href="matlab:helpview([docroot '/matlab/helptargets.map'], 'getting_started_python_interface')">Python を使う</a>」を参照してください。
名前 py.numpy.array を解決できません。

Note : The numpy is working successfully from Python as well as from MATLAB code.

Environment :

MATLAB 2020a

Python 3.7.7 (added to system path)

Windows 10 64 bit

What could be the problem for this ? Appreciate any workarounds.

Hi Varun Pai,

I have the same problem right now, do you fix it?

After loading Python in MATLAB using pyenv('Version', PythonPath), add PythonPath and <PythonPath>\Library\bin path to 'PATH' variable. Sample code

pyenv('Version', PythonExePath)
pyRootPath = fileparts(PythonExePath);
pathDelimiter = ';';
pathToAdd = {
    fullfile(pyRootPath)
    fullfile(pyRootPath, 'Library', 'bin')
    };
ENV = getenv('PATH');
ENV = strsplit(ENV, pathDelimiter);
ENV = [pathToAdd(:); ENV(:)];
ENV = unique(ENV, 'stable');
ENV = strjoin(ENV, pathDelimiter);
setenv('PATH', ENV);

Note: If there are multiple Python in your PATH varibale, it may not work as expected.
