Error in running example_generation file

[sakshamsingh1]

Hi, Thanks for the really useful library.

I followed all the steps in readme but I am getting this error while running the example_generation.py file.

  File "src/netCDF4/_netCDF4.pyx", line 2107, in netCDF4._netCDF4._ensure_nc_success
OSError: [Errno -101] NetCDF: HDF error: 'datasets/rir_datasets/spatialscaper_RIRs/bomb_shelter_mic.sofa'

Here is the entire traceback:

Please let me know, how can I fix this error?

Hi @sakshamsingh1 I believe that error can be fixed by including "from netCDF4 import Dataset" It may need to be placed before all other imports, or at least near the top.

@sakshamsingh1 were you able to solve your problem? Could you tell us what was the fix in your case?

Hi @iranroman, using "from netCDF4 import Dataset" on the top of the example_generation.py script fixed the error.
