   Thank you for trying that @davidhewitt. The difference between the libmxnet.so in the pip wheel and the one obtained via the build_from_source guide is that in the pip wheel a number of dependencies are statically linked to enable portability across various linux distributions and versions thereof. It's built on a CentOS 7 host for compliance with https://www.python.org/dev/peps/pep-0599/
   
   > Downgrading to a slightly older version of mxnet seems to work:
   > 
   > $ pip install mxnet==1.6.0b20200127
   > 
   > The libmxnet.so file in 1.6.0 is very broken. Not sure why the python3.8 interpreter doesn't crash. It also calls Py_FinalizeEx.

   @m-ou-se can you provide more details on why the file is broken? Specifically, I'm not sure if the issue at hand is really a build issue or rather a bug in the MXNet backend. Does your statement apply to the latest versions at https://dist.mxnet.io/python/cpu , for example https://repo.mxnet.io/dist/python/cpu/mxnet-2.0.0b20200720-py2.py3-none-manylinux2014_x86_64.whl
