Relative imports require the ‘package’ argument

I came to this question via Google, so I’ll answer what helped me (not directly related to the question).

I use importlib to dynamically import sub-packages given by a string.

import importlib
module_name="subpackage.i.import"
special_module = importlib.import_module(module_name, package=None)

This simply has to be adjusted to

import importlib
module_name="subpackage.i.import"
special_module = importlib.import_module(module_name, package="my_current_pkg")
