@chrishkchris I have fixed the average pool and max pool issues above in #746

However, for the equal, I found this is because there is some error when we do the sub operator for int32 input:

for example for input:

A = np.array([[[17, 4, 9, 22, 18], [-9, 9, -1, -1, 4], [1, 14, 7, 1, 4],
                [3, 14, -2, 3, -8]],
                [[-25, 6, 8, -7, 22], [-14, 0, -1, 15, 14],
                [1, 3, -8, -19, -3], [1, 12, 12, -3, -3]],
                [[-10, -14, -17, 19, -5], [-4, -12, 7, -16, -2],
                [-8, 3, -5, -11, 0], [4, 0, 3, -6, -3]]],
                    dtype=np.int32)
B = np.array([[[-6, -3, -8, -17, 1], [-4, -16, 4, -9, 0],
                [7, 1, 11, -12, 4], [-6, -8, -5, -3, 0]],
                [[-11, 9, 4, -15, 14], [18, 11, -1, -10, 10],
                [-4, 12, 2, 9, 3], [7, 0, 17, 1, 4]],
                [[18, -13, -12, 9, -11], [19, -4, -7, 19, 14],
                [18, 9, -8, 19, -2], [8, 9, -1, 6, 9]]],
                    dtype=np.int32)

The result of singa.__sub__(a, b) is:

[[[         -6          -3          -8         -17          17]

@dcslin can we fix it?

@chrishkchris chrishkchris changed the title Could we override the test precision atot of onnx test case, atol=1e-7 is too tough? Related to some test_onnx_backend.py test cases Jun 21, 2020

@chrishkchris I have fixed the average pool and max pool issues above in #746

However, for the equal, I found this is because there is some error when we do the sub operator for int32 input:

for example for input:

A = np.array([[[17, 4, 9, 22, 18], [-9, 9, -1, -1, 4], [1, 14, 7, 1, 4],
                [3, 14, -2, 3, -8]],
                [[-25, 6, 8, -7, 22], [-14, 0, -1, 15, 14],
                [1, 3, -8, -19, -3], [1, 12, 12, -3, -3]],
                [[-10, -14, -17, 19, -5], [-4, -12, 7, -16, -2],
                [-8, 3, -5, -11, 0], [4, 0, 3, -6, -3]]],
                    dtype=np.int32)
B = np.array([[[-6, -3, -8, -17, 1], [-4, -16, 4, -9, 0],
                [7, 1, 11, -12, 4], [-6, -8, -5, -3, 0]],
                [[-11, 9, 4, -15, 14], [18, 11, -1, -10, 10],
                [-4, 12, 2, 9, 3], [7, 0, 17, 1, 4]],
                [[18, -13, -12, 9, -11], [19, -4, -7, 19, 14],
                [18, 9, -8, 19, -2], [8, 9, -1, 6, 9]]],
                    dtype=np.int32)

The result of singa.__sub__(a, b) is:

@dcslin can we fix it?
