Remove block of Preprocessor operations using GraphSurgeon

Hi All.

I’m trying to implement fasterRCNN object detection model using TensorRT C/C++, but I need to remove some preprocessing and posprocessing operations in the Tensorflow frozen graph (pb file), because convert-to-uff is causing many errors with some unsupported layers. However until now I couldn’t find any solution to this problem. I know that I need to replace all of this operations using TensorRT plugins or any other approach.

Do you know some example where problematic nodes/operations had been removed.

Thanks for your help.
