I use tensorrt to accelerate my object detection code, but it report error as follows

I have some self-define tensorflow operator, such as GPU_NMS, soft-nms, roi_align, etc. I suspect the problem is that graph convert process can’t deal with self-define operator?
report error :

We created a new “Deep Learning Training and Inference” section in Devtalk to improve the experience for deep learning and accelerated computing, and HPC users:
https://devtalk.nvidia.com/default/board/301/deep-learning-training-and-inference-/

We are moving active deep learning threads to the new section.

URLs for topics will not change with the re-categorization. So your bookmarks and links will continue to work as earlier.

convert over!!!

I have the same problem, model input is 4D tensor with batch size=1 and channel=3.

I also met this problem on facenet.
