Here is the source code of the first test case `test_operator.test_convolution_grouping ` https://github.com/apache/incubator-mxnet/blob/master/tests/python/unittest/test_operator.py#L1674-L1703 ```python @with_seed() def test_convolution_grouping(): for dim in [1, 2, 3]: num_filter = 4 for num_group in [1, 2]: kernel = (3,) * dim shape = (1, 4) + (9,) * dim ``` The test will only fail when `dim=2` and `num_group=2`, i.e. when `kernel=(3, 3)` and `shape=(1, 4, 9, 9)`. So the test case will check if the Conv op will produce the same output and gradients (for x, w, b) when `num_group=2` as those of when we do the "grouping" manually. So it looks like for all of output, x gradient, w gradient, and b gradient the first halves of then tensors are the same, but the second halves differ. ``` Mismatched elements: 98 / 196 (50%) Max absolute difference: 16.347755 Max relative difference: 23.329699 x: array([[[[ 1.597207e-01, 1.540166e+00, 6.755731e+00, -5.728347e+00, 1.296894e+00, -1.326614e+00, 6.375989e+00], [ 1.170041e+00, 3.974693e-01, 5.603638e+00, -1.179677e+00,... y: array([[[[ 1.597207e-01, 1.540166e+00, 6.755731e+00, -5.728347e+00, 1.296894e+00, -1.326614e+00, 6.375989e+00], [ 1.170040e+00, 3.974691e-01, 5.603638e+00, -1.179677e+00,... ``` command: ``` nosetests-3.4 --with-coverage --cover-inclusive --cover-xml --cover-branches --cover-package=mxnet --with-timer --timer-ok 1 --timer-warning 15 --timer-filter warning,error --with-xunit --xunit-file nosetests_unittest.xml --verbose tests/python/unittest/test_operator.py:test_convolution_grouping ``` -- This is an automated message from the Apache Git Service.
