Comparing int8's gives Error Code 2: Internal Error (Assertion engine != nullptr failed. )

Description

class Traversability(nn.Module):
    def forward(self, untraversable: torch.Tensor) -> torch.Tensor:
        return (untraversable == 1) | (untraversable == 2)

...
    dummy_input = torch.randint(0, 4, (3, 224, 224), dtype=torch.int8)
...

results in

[04/08/2024-16:10:14] [TRT] [E] 4: input: input/output with DataType Int8 in network without Q/DQ layers must have dynamic range set when no calibrator is used.
[04/08/2024-16:10:14] [TRT] [E] 4: [network.cpp::validate::2772] Error Code 4: Internal Error (DataType does not match TensorFormats.)
[04/08/2024-16:10:14] [TRT] [E] 2: [builder.cpp::buildSerializedNetwork::751] Error Code 2: Internal Error (Assertion engine != nullptr failed. )
