KeyError: YOLODetector is not in the model registry.

[Jaykob]

Can somebody help me?
I guess it's a beginner's mistake...
I'm trying to train a YOLOX and basically took the available yolox config with small modifications and get the following error when trying to train:

KeyError: 'YOLODetector is not in the model registry. Please check whether the value of YOLODetector is correct or it was registered as expected.

OK it seems like it interferes with my mmdetection installation and it's model registry...

I see that the implementation / configs of YOLOX slightly differ between mmyolo and mmdetection.
Can somebody explain which one to prefer?
