[T-bagwell]

fix error message

Installing collected packages: torch ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. torchaudio 2.3.1 requires torch==2.3.1, but you have torch 2.0.1 which is incompatible.

when use pip install -r requirements.txt
