RecursionError when used on subclass of Tensor about pytorchviz HOT 5 CLOSED

I'm confused, why is a a view here?

from pytorchviz.

So the answer is: a is a view of torch.ones(5).

This actually seems like a Pytorch bug.

a = torch.ones(1)
b = torch.Tensor(a)
print(b._is_view()) # True
print(b._base is a) # True

a = torch.ones(1)
c = DummyTensor(a)
print(c._is_view()) # True
print(c._base is a) # False
print(type(c._base)) # <class '__main__.DummyTensor'>

c._base here creates a new DummyTensor, as per the docs

As of version 1.7.0, methods on torch.Tensor and functions in public torch.* namespaces applied on torch.Tensor subclasses will return subclass instances instead of torch.Tensor instances:

Yeah, agreed this is a bug.

As a workaround, do the _base object within the DisableTorchFunction context manager:

with torch._C.DisableTorchFunction():
  base = c._base

from pytorchviz.

This is indeed fixed by pytorch/pytorch#60464.
