joddiy commented on issue #565: fixed broadcast div pow URL: https://github.com/apache/singa/pull/565#issuecomment-559415745 Hi, @dcslin it works fine, however, I saw a little difference between the results of numpy and singa(for pow based gpu and div based cpu). ``` Mismatch: 10% Max absolute difference: 0.00073242 Max relative difference: 5.9753495e-07 x: array([[-3.58730e+01, -9.22379e+03, -1.86656e+00, 1.22574e+03, 1.13451e-01], [ 3.81203e+00, -1.25024e+01, -1.21589e+00, 1.68196e-01,... y: array([[-3.58730e+01, -9.22379e+03, -1.86656e+00, 1.22574e+03, 1.13451e-01], [ 3.81203e+00, -1.25024e+01, -1.21589e+00, 1.68196e-01,... ``` Not too big, I guess the problem is caused by floating-point precision, is that ok? @nudles
