sxjscience opened a new issue #12268: Inconsistent type conversion from numpy.ndarray to mx.ndarray
URL: https://github.com/apache/incubator-mxnet/issues/12268
 
 
   When we create a mxnet ndarray using a numpy ndarray, the dtype will not be automatically transferred. However, if we create a mxnet ndarray based on an existing mxnet ndarray, the dtype will be kept to be the same.
   
   Example: 
   ```python
   import mxnet as mx
   import numpy as np
   dat_np_to_mx = mx.nd.array(np.arange(10, dtype=np.int32))
   dat_mx_to_mx =mx.nd.array(mx.nd.arange(10, dtype=np.int32)) 
   print(dat_np_to_mx.dtype, dat_mx_to_mx.dtype)
   ```
   Result: 
   ```<class 'numpy.float32'> <class 'numpy.int32'>```
