Code Review

This pull request removes an informational log message that indicates when the Torch profiler is disabled. The change is intended to reduce log verbosity, as the profiler being disabled is the default state. The modification is simple, safe, and aligns with the goal of improving the user experience by cleaning up the logs. I approve of this change.
