Summary:

context

  • We found the new operator permute_multi_embedding can't support torch.float16 in an inference test
  • added test to cover the dtype support
  • before the operator change, we see the following error
Failures:

  1) torchrec.sparse.tests.test_jagged_tensor.TestKeyedTensorRegroupOp: test_multi_permute_dtype
    1) RuntimeError: expected scalar type Float but found Half
      File "torchrec/sparse/tests/test_jagged_tensor.py", line 2798, in test_multi_permute_dtype
        outputs = torch.ops.fbgemm.permute_multi_embedding(
      File "torch/_ops.py", line 1113, in __call__
        return self._op(*args, **(kwargs or {}))
  • suspicion is that in the cpu operator, there are tensor data access with data_ptr<float> in the code, which limited the dtype could only be float32
          auto outp = outputs[out_tensor][b].data_ptr<float>() + out_offset;
          auto inp = inputs[in_tensor][b].data_ptr<float>() + in_offset;

changes

  • use FBGEMM_DISPATCH_FLOATING_TYPES to dispatch the dtype to template scalar_t.
  • after the change the operator can support float16, bfloat16

WARNING: somehow this operator still can't support int types.
