HI,
I can’t import tensorrt in python3
This is my error msg.

import tensorrt

from .tensorrt import *
ImportError: /lib/aarch64-linux-gnu/libnvinfer.so.8: undefined symbol: _ZN5nvdla8IProfile17setUseSoftMaxOptzEb

so i want to reinstall tensorrt but I can’t remove it.

nvidia@nvidia-desktop:~$ python3 -m pip uninstall tensorrt

how can i reinstall tensorrt??

You can install NVIDIA SDK Manager to your PC and select the Download Only option, it will download the original debian packages to your PC, which you could then copy to your Jetson and install with dpkg.

Can you explain more detail for me??
I understand about pkg download via sdkmanager. after that how should I do ??

I want to forced reinstall tensorrt…

sorry
I understood and trying now!!

I can’t import tensorrt in python3 after installation from .deb pkg file of tensorrt.

is it correct??

but I can find tensorrt pkgs with command : “dpkg -l | grep TensorRT”.

Hi,

It looks like you are using JetPack 4?

We only provide the prebuilt package for the default Python package.
For JetPack 4, it’s Python 3.6.

If you need the binding for other Python versions.
Please follow the guide below to build a custom binding.

Thanks.
