[BUG] .exo mesh creation

[MelissaCastellan]

I'm trying to use meshio to convert mesh files from .vtk to .exo format but I get this error:

meshio.write("/home/melissa/bilanciere/Cubo.exo", mesh) Traceback (most latest call last ): File "", line 1, in File "/home/melissa/.local/lib/python3.6/site-packages/meshio/_helpers.py", line 141, writing return writer(filename, mesh, **kwargs) File "/home/melissa/.local/lib/python3.6/site-packages/meshio/exodus/_exodus.py", line 263, writing with netCDF4.Dataset(filename, "w") as rootgrp: File "src/netCDF4/_netCDF4.pyx", line 2463, in netCDF4._netCDF4.Dataset.init File "src/netCDF4/_netCDF4.pyx", line 2026, in netCDF4._netCDF4._ensure_nc_success OSError: [Errno -101] NetCDF: HDF error: b'/home/melissa/bilanciere /Cubo.exo'

On the other hand, it creates other formats like .stl without problems.
