Hello,
I am trying to work with tensorrt python library in my poetry environment already for few days and I cant find a way to solve this issue…
I am using Nvidia Jetson Xavier AGX with Jetpack5.1.1
cuda version 11.4.315
I am using Python3.8 with poetry as the dependancy manager
I build tensorrt-8.5.2.2-cp38-none-linux_aarch64.whl and installed it in this way “poetry add tensorrt-8.5.2.2-cp38-none-linux_aarch64.whl”
I also tried to install it in this way “poetry shell” “pip3 install tensorrt-8.5.2.2-cp38-none-linux_aarch64.whl”
please help me solve this very annoying issue, thanks.

Hi,

We have prebuilt for python3.8 so you don’t need a custom package.
Could you try to install it with the following command in poetry to see if it helps?

$ sudo apt install python3-libnvinfer*

Thanks.

Hi,
I tried the command that you sent and it did not install anything new.

Because I am using poetry for my dependencies manager I installed the TensorRT package as a whl file.

Hi,

We recommend installing a Python deb instead of whl.
Could you remove the wheel and install Python TensorRT again?

Thanks.
