joddiy opened a new issue #633: Cannot do mul for int tensors
URL: https://github.com/apache/singa/issues/633
 
 
   Hi, @dcslin , we cannot do the mul operator for int tensors:
   
   The error is:
   > F0324 05:04:22.542809 14739 tensor.cc:932] Unknown combination of data type kInt and
language kCuda
   
   please use this test case:
   ```python3
   x1 = np.array([1], dtype=np.int32)
   x2 = np.array([256], dtype=np.int32)
   x1 = tensor.from_numpy(x1)
   x1.to_device(gpu_dev)
   x2 = tensor.from_numpy(x2)
   x2.to_device(gpu_dev)
   
   y = autograd.Mul()(x1, x2)
   print(tensor.to_numpy(y[0]))
   ```
