Importing 3D .msh file into Fenics as mesh

Thanks for your reply! I have tried running the code you have provided which leads me to this error message:

 /home/fenics/.local/lib/python3.6/site-packages/h5py/__init__.py:40: UserWarning: h5py is running against HDF5 1.10.0 when it was built against 1.10.4, this may cause problems

I have tried fully uninstalling both meshio and h5py but this still gives me this error message. I have also tried reinstalling both of these modules as described within this thread Gmsh 4.4.1 in FEniCS? Meshio
but I then obtain:

ERROR: Command "/usr/bin/python3 -u -c 'import setuptools, tokenize;__file__='"'"'/tmp/pip-install-19z847ve/h5py/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' install --record /tmp/pip-record-s2dwmcju/install-record.txt --single-version-externally-managed --compile --user --prefix=" failed with error code 1 in /tmp/pip-install-19z847ve/h5py/

For reference, I am running all of this within Docker version 19.03.5, build 633a0ea838f1
