How to use Python on Webapp Server running on Windows?

I have created predict.py and added to .ctf, In startup I have used following code

if isdeployed
    
    pyenv(Version="C:\Users\MatlabWebAppVM\AppData\Local\Programs\Python\Python39");
    [filepath,~,~] = fileparts(mfilename('fullpath'));
    insert(py.sys.path, int64(0), filepath);

end

Getting this error while running on server
