Full arch code FasterRcnn with resnet50

Hi,

I would like to convert my own model (fasterRcnn train with tensorflow object detection api) to tensorrt engine via tlt.
My reference to conversion is the one of your pretrained model which - FaterRcnn with resnet50 (keras based).
In order to do so i need to adjust my model to the one of yours.

I would like to know if the source code (the full architecture) of the FasterRcnn (.h5) is available?
In general, i would like to know what is the fastest way to convert tensorflow model such as one i have to .etlt and than to .engine without retrain.

Thanks

TLT is not open-source yet.
No third party pre-trained models are supported by TLT. TLT does not support convert tf model to etlt model.
