How to install TensorRT?

I have Jetpack 5.1.1 installed, and I am using a Nvidia Jetson AGX Orin 32GB H01.
I want to use TensorRT to optimize and speed up YoloP, so I used the command sudo apt-get install tensorrt nvidia-tensorrt-dev python3-libnvinfer-devto install TensorRT.
I cannot import tensorrt while i am in my virtual environment, so I used the command pip install nvidia-tensorrt, but it gave an error message.

pip install pycuda and pip install nvidia-tensorrt fail, but I am able to import tensorrt while i am outside the virtual environment and cd Home

Hi,

Please install TensorRT python with the below command:

Thanks.

Hi,

I have run the command and it says libnvinfer-dev and libnvinfer is already the newest version (8.4.1-1+cuda11.4).

The problem is I cannot import tensorrt while i am in a virtual environment. How do I change that?

Hi,

Could you try to create the virtul environment with --system-site-packages?
Thanks.
