🐛 Describe the bug
Recent bug #120482 was due to someone directly accessing TensorVariable.size; fixed in #120567. But this field is None when the tensor has dynamic shapes. This is a dynamic shapes footgun. Either ban this, or change this to query size off of the fake tensor (and be willing to return SymInts).
