xidulu commented on issue #16646: [Bug][Numpy] zeros_like, ones_like does not respect dtype flag
URL: https://github.com/apache/incubator-mxnet/issues/16646#issuecomment-546910645
 
 
   I take a brief look at the `infertype` function for `zeros_like`:
   https://github.com/apache/incubator-mxnet/blob/master/src/operator/numpy/np_init_op.cc#L103
   The parameter type seems to be ignored.
   The following experiment verified my conjecture:
   ```
   In [1]: from mxnet import np
   
   In [2]: a = np.ones(10)
   
   In [3]: b = np.zeros_like(a, dtype="Life is short, use Pytorch")
   
   In [4]: b
   Out[4]: array([0., 0., 0., 0., 0., 0., 0., 0., 0., 0.])
   
   In [5]: b.dtype
   Out[5]: dtype('float32')
   ```
