About quantization scheme

[NoLookDefense]

Hello. Thanks for your work.I am a newcomer of quantization, and I feel confused about the quantization scheme.
It seems that it has so many configurations, like uniform, bops, model size, latency, etc. Could you please explain the differences between these models, and how to train these model?
