Issue Fixes #193933 Summary Dynamo models a tensor subclass without __torch_dispatch__ as a TensorWithTFOverrideVariable holding the Python type in class_type , while the fake tensor behind the proxy stays a plain FakeTensor . When an inplace op bumps the fake version, synchronize_attributes re-derives every specialized property from that fake tensor, and get_specialized_props resolves class_type back to torch.Tenso…
