   The id of np.int64 in scipy is different from that in numpy.
   ```python
   import numpy as np
   import scipy as sp
   import mxnet as mx
   
   one = np.ones((2, 2), dtype='int64')
   sp_one = sp.sparse.csr_matrix(one).data
   
   print (np.dtype(sp_one.dtype).type)
   print (id(np.dtype(sp_one.dtype).type))
   
   print (np.dtype(np.int64).type)
   print (id(np.dtype(np.int64).type))
   
   print (np.int64)
   print (id(np.int64))
   ```
   
   ```bash
   <type 'numpy.int64'>
   139671667680256
   <type 'numpy.int64'>
   139671667680672
   <type 'numpy.int64'>
   139671667680672
   ```
