"FasterRCNN: 'OPA_FPN is not in the models registry'"

Hello, I'm very interested in your work about FPN，but When I try to debug code，I using the image_demo script in the demo directory as well as using faster_rcnn_r50_opa_fpn_112_sml1_coco for config. However, it's report a error :
"FasterRCNN: 'OPA_FPN is not in the models registry'"

I have no idea，Hope you can give me a solution

Thanks for your interest! Maybe you need to run python setup.py develop first. Please refer to install.md for installation and dataset preparation.

Thanks，I've solved this problem。
Now I want to ask, how to use the script in the code to debug. Because the image_demo script given in the source code, there are only have model initialization, image prediction and drawing prediction results.

I didn't find the implementation of preprocessing the input of a batch images, then model propagate and calculating loss.

In addition, README only gives the method of using .sh method to train as well as predict, and does not find how to call a script to debug the model. e.g. using one script of the source code to debug how does a batch image preprocess, propagate and compute loss?
