Incorrect Expected Result in test_logsumexp_out Unit Test for torch_scatter.scatter_logsumexp

[finalyXG]

Hi team,

I am running the below unit test in "//pytorch_scatter/test/composite/test_logsumexp.py", and the test case is failed.

def test_logsumexp_out():
    src = torch.tensor([-1.0, -50.0])
    index = torch.tensor([0, 0])
    out = torch.tensor([-10.0, -10.0])
    scatter_logsumexp(src=src, index=index, out=out)
    assert out.allclose(torch.tensor([-0.9999, -10.0]), atol=1e-4)

I find the "out" is tensor([-0.9999, 0.0000]), not close to the expected tensor "torch.tensor([-0.9999, -10.0])".

any ideas about it?

Thanks!
