add netCDF dependency required by ONNS app

[Andreas Janz]

ModuleNotFoundError: No module named 'netCDF4'

[Benjamin Jakimow]

This probably leads to errors with the netCDF libs used by GDAL

[Andreas Janz]

Have you tried?

On my QGIS, there is no netCDF4 pre-installed.

[Benjamin Jakimow]

I expect it, as gdal uses it’s own netCDF lib. Please test it first before you add the netcdf4 dependency to the requirements.txt

[Andreas Janz]

Works for me.

C:\QGIS>pip install netCDF4 --user

@Benjamin Jakimow be sure to install netCDF4 and not netCDF

I assume it is not possible to GDALize the ONNS app? Would be the nicest solution…
