protobuf is required to run MusicGen. Why isn't it part of the requirements?

[snatalius]

I encountered an error while trying to generate music for the first time using MusicGen, and after some troubleshooting I found that I need to pip install protobuf. I'm wondering why it is not installed at the first place. Should it be part of the requirements?

hey @snatalius i encountered the same, i guess it was overlooked.
i only came across the same issue myself after not using google colab, adding it to the requirements.txt did solve the issue.

this is actually a bug in HF Transformers huggingface/transformers#25684
