beep boop 🤖: 🚨 The following files must be fixed before merge!

---

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

************* Module utils
scripts/llm/performance/utils.py:132:0: C0115: Missing class docstring (missing-class-docstring)
scripts/llm/performance/utils.py:144:0: C0116: Missing function or method docstring (missing-function-docstring)
scripts/llm/performance/utils.py:173:0: C0116: Missing function or method docstring (missing-function-docstring)

-----------------------------------
Your code has been rated at 9.97/10

---

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!
