   Thanks for your work.
   
   But I have problems with your pre-built wheel.
   
   after installed your wheel with pip, I copyed libmxnet.so with:
   ```sh
   cp ./.local/mxnet/libmxnet.so /home/david/.local/lib/python3.6/site-packages/mxnet/libmxnet.so
   ```
   
   After that, I got this error:
   ```sh
   david@TinyNuke:~$ python3 mnist_cnn.py 
   Traceback (most recent call last):
     File "mnist_cnn.py", line 2, in <module>
       import mxnet as mx
     File "/home/david/.local/lib/python3.6/site-packages/mxnet/__init__.py", line 24, in <module>
       from .context import Context, current_context, cpu, gpu, cpu_pinned
     File "/home/david/.local/lib/python3.6/site-packages/mxnet/context.py", line 24, in <module>
       from .base import classproperty, with_metaclass, _MXClassPropertyMetaClass
     File "/home/david/.local/lib/python3.6/site-packages/mxnet/base.py", line 213, in <module>
       _LIB = _load_lib()
     File "/home/david/.local/lib/python3.6/site-packages/mxnet/base.py", line 204, in _load_lib
       lib = ctypes.CDLL(lib_path[0], ctypes.RTLD_LOCAL)
     File "/usr/lib/python3.6/ctypes/__init__.py", line 348, in __init__
       self._handle = _dlopen(self._name, mode)
   OSError: /home/david/.local/lib/python3.6/site-packages/mxnet/libmxnet.so: cannot open shared object file: No such file or directory
   
   ```
   
   Then I figured out your wheel is packed with a x86-64 arch libmxnet.so:
   ```sh
   david@TinyNuke:~$ ls -lah /home/david/.local/lib/python3.6/site-packages/mxnet/libmxnet.so
   -rwxrwxr-x 1 david david 364M 6月   7 22:22 /home/david/.local/lib/python3.6/site-packages/mxnet/libmxnet.so
   david@TinyNuke:~$ file /home/david/.local/lib/python3.6/site-packages/mxnet/libmxnet.so
   /home/david/.local/lib/python3.6/site-packages/mxnet/libmxnet.so: ELF 64-bit LSB shared object, x86-64, version 1 (GNU/Linux), dynamically linked, BuildID[sha1]=5b07574bc684f6acdef5ba509889ad9c8298d157, with debug_info, not stripped
   d
   ```
   Local dynamic library on jetson nano looked like this:
   ```sh
   file /usr/local/cuda/lib64/libcudart.so.10.0.166
   /usr/local/cuda/lib64/libcudart.so.10.0.166: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, stripped
   ```
