Thanks for your issue,
This is indeed a very interesting use case.
I noticed that this problem also occurred in PyTorch:
```python
>>> inputs = torch.tensor([1,1,1])
>>> fake_data = torch.tensor([1,1,0])
>>> 1 - (inputs == fake_data)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/ubuntu/anaconda3/lib/python3.7/site-packages/torch/tensor.py",
line 394, in __rsub__
return _C._VariableFunctions.rsub(self, other)
RuntimeError: Subtraction, the `-` operator, with a bool tensor is not
supported. If you are trying to invert a mask, use the `~` or `logical_not()`
operator instead.
>>>
```
If we are capable of providing a solution to this case, that would be a huge
advantage over PyTorch.
