zheng-da opened a new issue #12843: MXNet doesn't work with scipy int64
URL: https://github.com/apache/incubator-mxnet/issues/12843
 
 
   The following code doesn't work.
   ```python
   import numpy as np
   import scipy as sp
   import mxnet as mx
   
   one = np.ones((2, 2), dtype='int64')
   print(np.dtype(one.dtype).type == np.int64)
   sp_one = sp.sparse.csr_matrix(one).data
   mx.nd.array(sp_one, dtype=sp_one.dtype)
   ```
   It generates the error as below:
   ```
   Traceback (most recent call last):
     File "test.py", line 8, in <module>
       mx.nd.array(sp_one, dtype=sp_one.dtype)
     File "/home/ubuntu/incubator-mxnet/python/mxnet/ndarray/utils.py", line 146, in array
       return _array(source_array, ctx=ctx, dtype=dtype)
     File "/home/ubuntu/incubator-mxnet/python/mxnet/ndarray/ndarray.py", line 2488, in array
       arr = empty(source_array.shape, ctx, dtype)
     File "/home/ubuntu/incubator-mxnet/python/mxnet/ndarray/ndarray.py", line 3874, in empty
       return NDArray(handle=_new_alloc_handle(shape, ctx, False, dtype))
     File "/home/ubuntu/incubator-mxnet/python/mxnet/ndarray/ndarray.py", line 139, in _new_alloc_handle
       ctypes.c_int(int(_DTYPE_NP_TO_MX[np.dtype(dtype).type])),
   KeyError: <type 'numpy.int64'>
   ```
