beep boop 🤖: 🙏 The following files have warnings. In case you are familiar with these, please try helping us to improve the code base.

Your code was analyzed with PyLint. The following annotations have been identified:

************* Module hf
examples/llm/peft/hf.py:26:0: C0116: Missing function or method docstring (missing-function-docstring)
************* Module nemo.collections.llm.peft.lora
nemo/collections/llm/peft/lora.py:158:4: C0116: Missing function or method docstring (missing-function-docstring)

-----------------------------------
Your code has been rated at 9.89/10

---

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!
