I'm adding accelerate as one of the libraries to install because otherwise when running the Trainer, the model errorr out with the error. 

ImportError: Using the `Trainer` with `PyTorch` requires `accelerate>=0.20.1`: Please run `pip install transformers[torch]` or `pip install accelerate -U`

Further context: 
1. I've tried this across different environments so I believe that the environment is not the issue. 
2. I had the latest transformers library version running. 
3. Typically even after install accelerate and import it, it wouldn't resolve the issue until I restart the notebook and try again.
