Pycharm can not find declarication to go

[Jingnan-Jia]

In https://github.com/Project-MONAI/tutorials/tree/master/3d_segmentation/challenge_baseline, Pycharm can not track the usage of some submodules.

To be specific, when I use "Ctrl+ LeftClick" to try to jump to the source file of monai.engines.SupervisedEvaluator, Pycharm show warning "can not find declarication to go"

I think this is because that the modules are not imported explicitly in monai/__init__.py like "from .engines import *"???

Is this my personal issue? you can try to reproduce this issue in your pycharm using this file

Hi @wyli ,

Did you see this issue in your env before? Or it's known question?
Thanks.

this is a valid issue, pycharm doesn't know how to resolve the module imported with optional_import. for now I don't know how to fix it, let's keep this ticket open. I marked it contribution wanted

@wyli Why do we need optional_import ? Why not import those packages directly?
