Uint8 quantimization of new mode failed!

Hi ,
As we know, Tengine supply the quantimization tool of some model, yet , it we need to quantimize the new model such as litehrnet and movenet etc, how should we do?
What I know the document of quantimization is some example of yolo model quantimization as KHADAS’s npu sdk demo, any other weblink could help ?
Looking forward to your reply!
