Hi, thanks for your interest. What's the difference between this gradio app and the demo we provided? And what's the difference between this inference code and this quantitative inference code?

[LuthandoMaqondo]

Thank you for the response, the main contribution is for someone to:

1. effortlessly run the Gradio app locally (thanks to the supported Quantization).
2. The inference script I added in the scripts folder is directly adapted from the quantitative inference code, again to facilitate easy local testing of the model developments as they progress.

I believe this is Repo presents a great work thus it would be best if more people could play around, build upon and contribute.

Thanks. I think you can add the quantization-related code to the sample_t2x.py file. I'll merge this with it if the tests pass.

@LuthandoMaqondo, thank you very much for your PR. However, since we have already provided a Gradio app ourselves, we feel that it might not be necessary if the Gradio app you provided isn't significantly different from ours. I think you could consider developing a ComfyUI for Latte if you are willing to do so.
