fix: mcore_ckpt_to_nemo.py broken from load_mlm arg
State: open | Pull request: yes
Labels: name: NLP

name: Run CICD

In examples/nlp/language_modeling/megatron_ckpt_to_nemo.py, the introduction of load_mlm in this invocation

https://github.com/NVIDIA/NeMo/blob/5ed118f24c31ba1e4729ff3fae33dc8482bd1b64/examples/nlp/language_modeling/megatron_ckpt_to_nemo.py#L203

causes an error because load_mlm is not excluded from the model config during the update in nlp_model.py. This change just excludes all keys not in the model config to avoid this kind of error for other kwargs that aren't model config args.

Mitigation guide:

* Add sensible and useful docstrings to functions and methods
* For trivial methods like getter/setters, consider adding `# pylint: disable=C0116` inside the function itself
* To disable multiple functions/methods at once, put a `# pylint: disable=C0116` before the first and a `# pylint: enable=C0116` after the last.

By applying these rules, we reduce the occurance of this message in future.

Thank you for improving NeMo's documentation!
