Subject: [PATCH] Python 3.12 compatibility: adjust submodule imports
|
||||
|
||||
importlib imports behave differently in py 3.11 and py 3.12: py 3.12
|
||||
requires explicit imports of the submodules.
|
||||
|
||||
While fixing this, reduce the imports to the used submodules. Currently,
|
||||
the base is still imported automatically.
