Issue with Windows Quickstart Guide.

[pmusser]

Not sure where else to mention this -- the windows quickstart guide worked a dream up until actually running the demo.py for both hf and ModelScope. The issue I continually ran into was:

"ImportError: This modeling file requires the following packages that were not found in your environment: transformers_stream_generator. Run `pip install transformers_stream_generator`"

I did a bit of googling which recommended that I downgrade transformers to anything pre 4.37. I did so (ending up with 4.36.2), and that seemed to resolve the issue which let the sample code run. Hooray!

Not sure at which step I ended up loading an incompatible version of transformers, but wanted to mention it here since a search of existing issues didn't seem to cover it already.

Hi @pmusser , we confirmed that this issue can be reproduced. It is due to a change in transformers 4.37.0. When importing transformers_stream_generator, from transformers.generation.utils import GenerateOutput, SampleOutput, logger requires SampleOutput, however SampleOutput is removed in the lastest transformers. A workaround is to use transformers==4.36.2.

We are going to replace the model used in demo.py so as not to confuse new-comers :)
