What & where is the .nemo file?
Hello!

I would like to run the train_kenlm.py file but I do not understand all the arguments it requires: 

I read the documentation (https://docs.nvidia.com/deeplearning/nemo/user-guide/docs/en/main/asr/asr_language_modeling.html and I ran install_beamsearch_decoders.sh as well, so I have the kenlm bin root but I have no idea how to get the root of the .nemo file and what it is about?

Thanks in advance!
