===========

**Error message**: Shift-right-arithmetic operation on non 32-bit inputs is not supported. Cast the first argument's data type to be S32, U32, or F32.

Erroneous code example:

.. code-block:: python

    def forward(self, input, other):
        return torch.bitwise_right_shift(input, other)
    
    # This will be the first argument and must be 32-bit
    input = torch.tensor([16, 32, 64], dtype=torch.int16)
    # The second argument can be non 32-bit
    other = torch.tensor([1, 2, 3], dtype=torch.int16)


To fix this error:

.. code-block:: python

    def forward(self, input, other):
        return torch.bitwise_right_shift(input, other)

    # Correctly setting the first argument to be 32-bit
    input = torch.tensor([16, 32, 64], dtype=torch.int32)
    other = torch.tensor([1, 2, 3], dtype=torch.int16)
