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'> ```
