Thanks Ryan. This problem has now been resolved. I did have netcdf4 but was missing hdf4, which is the reason that netcdf4 module won't load. I am a little surprised, if hdf4 is a dependency (lack of which doesn't even allow the module to load), then why is not automatically installed when conda installs netcdf4? A similar issue was raised here - https://github.com/Unidata/netcdf4-python/issues/574

Working on sharing the file now.

I get this error when I tried xr.open_dataset(os.path.join(ddir, 'PHY_FLUXES_FILES/roms_dia_avg_y17.nc'), engine='netcdf4')

ImportError: libmfhdf.so.0: cannot open shared object file: No such file or directory

I already had netcdf4 installed. I am able to open other netcdf files.

I get a similar error when I use open_dataset --
