Why can't PyCharm show PyTorch Module object attributes in debug mode

Question

I define a sub-class of PyTorch's Module in PyCharm and create an instance a :

from torch.nn import Module

class AModule(Module):
    def __init__(self):
        self.something = 10

    def __repr__(self):
        return "AModule"

a = AModule()

If I run the debugger and examine a , I can't see its attributes:

I checked and Module is written in Python (as opposed to being implemented in C), so why is that?

Answer 1

This is caused by not having properly initialized Module with a super call in the first like of __init__ :

super(AModule, self).__init__()

However, PyCharm could have shown more useful information, so I created this issue .
