   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
