tensorrt5.0 sample_uff_ssd error in xzvier

I am very happy to buy xzvier for development.I evaluated the performance of xzvier, which is about 2 times stronger than that of TX2.No 20 times exaggerated by Lao Huang.And when I tested the tensorrt performance of Xavier, the following error occurred.
…/data/ssd/sample_ssd.uff
Begin parsing model…
ERROR: UFFParser: Validator error: NMS: Unsupported operation _NMS
ERROR: sample_uff_ssd: Fail to parse

Hello,

The error indicates _NMS is an unsupported TRT op. The list of supported TensorFlow ops are mentioned on the dev guide, https://docs.nvidia.com/deeplearning/sdk/tensorrt-developer-guide/index.html#support_op

Recommend the option to implement a plugin layer for the unsupported operation or modify the original network to remove this operation. Could try using graphsurgeon for this.
