joddiy commented on issue #744: URL: https://github.com/apache/singa/issues/744#issuecomment-646732001 @chrishkchris I have fixed the average pool and max pool issues above. 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] [ -9 -3 -1 -1 3] [ -6 -3 -8 -17 3] [ -6 -3 -2 -17 -8]] [[ -25 -3 -8 -7 21] [ -14 -3 -1 -17 13] [ -6 -3 -8 -19 -3] [ -6 -3 -8 -3 -3]] [[ -10 -14 -17 -17 -5] [ -4 -12 -8 -16 -2] [ -8 -3 -5 -11 -2147483647] [ -6 -3 -8 -6 -3]]] Fs[[[ -6 -3 -8 -17 17] [ -9 -16 -1 -1 4] [-2147483642 13 -2147483644 -12 0] [ -6 -8 -2 -3 -8]] [[ -25 -2147483645 4 -7 8] [ -14 -2147483637 -1 -10 4] [ -4 -2147483639 -8 -19 -3] [-2147483642 12 -2147483643 -3 -3]] [[ -10 -14 -17 10 -5] [ -4 -12 -7 -16 -2] [ -8 -2147483642 -5 -11 -2] [-2147483644 -2147483639 -1 -6 -3]]] ``` @dcslin can we fix it? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
