TensorRT Detectron2 webcam


Hello Everyone!
So after a lot of tries, I was finally able to develop a TensorRT engine for the detectron2’s mask-rcnn in the docker.
While I did do inference to check the performance, I was wondering if you guys could advice me something.

I want to do real-time inference with a webcam so if you know anything, it would be a big help.
Of course, I am trying to develop the code myself too but it would be a big help if you could perhaps point me to the right direction.

I am also simultaneously doing it on Jetson now that I have updated my jetpack to 5.1.

Thank you all!


TensorRT Version:
CUDA Version: 11.8
CUDNN Version: 8.6
Operating System + Version: Ubuntu20.04
Python Version (if applicable): 3.8
PyTorch Version (if applicable): 2

This looks like a Jetson issue. Please refer to the below samples in case useful.

For any further assistance, we will move this post to to Jetson related forum.


I apologize if I did not make myself clear,
I already created the tensorrt engine for detectron2.

I just want to run inference using a webcam so I was asking for ideas here.

Hi @rajupadhyay59 ,
Please refer to the link for understanding and performing inference on TRT engine.


@AakankshaS Thank you for the reply, but I already solved the problem.
Thanks, everyone!
