Can I add data preprocessor to the exported model ?

[CescMessi]

In mmengine, data preprocessor and model forward are separated, resulting in models exported by mmdeploy that do not contain data preprocessor. I had to manually add the normalization part when using the exported model. I know that rewriting the forward function can do it, but it will result in repeated normalization when exporting. Is there any easier way to do that?

mmdeploy SDK already supports that.
You can use --dump-info when exporting a model, and use mmdeploy SDK's API to do model inference.
