Hi James,
I understand that you want the app-designer app to detect the python versions installed and select the required one.
Please follow the below mentioned steps to detect and select the version:
1. Check the installed Python versions:
pyVersions = pyversion;
The `pyversion` function returns a structure containing information about the installed Python versions.
2. Iterate through the installed Python versions and select the desired one:
desiredVersion = '3.8'; % Specify the desired Python version
selectedVersion = '';
for i = 1:numel(pyVersions)
if strcmp(pyVersions(i).Version, desiredVersion)
selectedVersion = pyVersions(i).Executable;
break;
end
end
In this example, the `desiredVersion` variable is set to the Python version you want to select. The loop iterates through the `pyVersions` structure and checks if the version matches the desired version. If a match is found, the `selectedVersion` variable is set to the executable path of the desired Python version.
3. Set the selected Python version for MATLAB:
if ~isempty(selectedVersion)
pyversion(selectedVersion);
else
error('Desired Python version not found.');
end
The `pyversion` function is used to set the selected Python version for MATLAB. If a matching version is found and `selectedVersion` is not empty, the selected version is set using `pyversion`. Otherwise, an error is thrown indicating that the desired Python version was not found.
By incorporating these steps into your app, you can check the installed Python versions and automatically select the desired version without requiring manual input from the user.
Hope this answers your question.
