Cannot import MXNet in Spaces

I am trying to use MXNet in Spaces and I have several questions on MXNet support.
I put mxnet-cu102mkl==1.6.0.post0 in the requirements.txt and prepared which (indirectly) imports MXNet.

When pushed my app to Spaces, I got a runtime error, as follows:

Traceback (most recent call last):
  File "", line 12, in <module>

    ... (omitted)

  File "/home/user/app/coordinate_reg/", line 4, in <module>
    import mxnet as mx
  File "/home/user/.local/lib/python3.8/site-packages/mxnet/", line 24, in <module>
    from .context import Context, current_context, cpu, gpu, cpu_pinned
  File "/home/user/.local/lib/python3.8/site-packages/mxnet/", line 24, in <module>
    from .base import classproperty, with_metaclass, _MXClassPropertyMetaClass
  File "/home/user/.local/lib/python3.8/site-packages/mxnet/", line 214, in <module>
    _LIB = _load_lib()
  File "/home/user/.local/lib/python3.8/site-packages/mxnet/", line 205, in _load_lib
    lib = ctypes.CDLL(lib_path[0], ctypes.RTLD_LOCAL)
  File "/usr/local/lib/python3.8/ctypes/", line 373, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: cannot open shared object file: No such file or directory

I assume there are no CUDA related files below /usr/local/ or any other paths.

My question are:
(1) Is it possible to somehow use MXNet in Spaces (without causing errors)?
(2) If not, how do I build a customized container environment to suit my app’s requirements?
I once saw a description that says I should contact the team to do so, is it the right way?
