Package imp deprecated

Development
1

The package imp is deprecated in python since version 3.4 and will be removed. This is critical as the button reload of the modules strongly depends on this package. I didn’t succeed to replace it with the recommended importlib, but maybe somebody has already created something.

I have tried overriding the onReload method, it runs without error but it does not do what it is intended, the submodules are still not reloaded:

def onReload(self):
        """
        Override reload scripted module widget representation.
        """
        logging.debug("Reloading Dosimetry4D")
        submoduleNames=['Dosimetry4DLogic', 'Dosimetry4DTest', 'fit_values', 'PhysicalUnits']
        import importlib
        for submoduleName in submoduleNames:
            module = importlib.import_module(".".join(['Logic', submoduleName]))
            importlib.reload(module)
            
        if isinstance(self, ScriptedLoadableModuleWidget): # Mandatory for now, reloading the widget
            ScriptedLoadableModuleWidget.onReload(self)

I made it to work with the following:

import importlib
mod = importlib.import_module('Logic', __name__)
importlib.reload(mod)
__submoduleNames__=['Dosimetry4DLogic', 'Dosimetry4DTest', 'fit_values', 'PhysicalUnits']

# and then...
    def onReload(self):
        """
        Override reload scripted module widget representation.
        """
        logging.info("Reloading Dosimetry4D")
        importlib.reload(mod)
        for submoduleName in __submoduleNames__:
            mod1 = importlib.import_module('.'.join(['Logic',submoduleName]), __name__)
            importlib.reload(mod1)

        if isinstance(self, ScriptedLoadableModuleWidget):
             ScriptedLoadableModuleWidget.onReload(self)
