1、deploy to onnx failed. cannot export pth to onnx.

As a workaround, the current "Codebases" registry in "mmdeploy" is used to build instance. This may cause unexpected failure when running the built modules. Please check whether "mmyolo" is a correct scope, or whether the registry is initialized.

2、How to merge the pred bboxs and labels into one output feature.
I couldn't find a way to modify the output nodes in this project. I don't know how the model is constructed. Does mmengine provide an API that allows modifying nodes during the model export to ONNX？

By the way, using mmengine seems has made this project less user-friendly.

Sorry for the delay.

1. According to the error message, the mmyolo may not be installed. We suggest reinstalling mmyolo.
2. To merge the two outputs, we think the mmdepoly may not provide API to do this, and you can manage the output in the code of the head. The appendix is a simple deploy code (without postprocess) with only ONNX. Hope it can help.

The code of mmlab may be complicate. We will try to transfer our code into ultralytics.

Thanks for your interest in our work!
Best Wishes! 😊
