Hi Bastiaan,
One workaround is to add the path of the directory that contains the Python file with the function you need, using the Python sys module.
For example, in the setupImpl function before the module gets imported:
function setupImpl(obj)
pyrun("import sys");
pyrun("sys.path.append('directory')");
py.importlib.import_module('simple_function');
end
Greetings,
Caspar
