Unit tests are invalid

[noa-codes]

Hi - Thanks for this terrific paper and thank you for sharing the code!

Just wanted to point out that the tests in tests/test_asl.py are not valid, and they all fail, e.g.

======================================================================
FAIL: test_forward_clipped_logits (tests.test_asl.TestAsymmetricLoss)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/Users/nbenditshtull/development/ASL/tests/test_asl.py", line 62, in test_forward_clipped_logits
    self.assertEqual(self.loss(x, y), expected_loss)
AssertionError: tensor(3.8641) != tensor(0.3188)

======================================================================
