I’m not aware of any official Mask-RCNN examples with TensorRT, however there seems to be a few options for getting Mask-RCNN on a Jetson.
- Mask-RCNN with Mobilenet meant for Jetson - https://github.com/gustavz/Mobile_Mask_RCNN
- Some models on Jetson with tf_trt - https://github.com/NVIDIA-AI-IOT/tf_trt_models/blob/master/tf_trt_models/detection.py
Perhaps the first link may be enough for your purposes without TensorRT, but you may be able to use these to get a TensorRT Engine for additional performance.
A general TensorRT workflow is TensorFlow -> UFF -> TensorRT+Plugin, and you can find some samples for each step in /usr/src/tensorrt.
