Tensorrt not working and not able to install in the 4.6 image

[AINacster]

Tensortrt does not work. I am trying to run simple code in python3 -
import tensorrt as trt
trt.version

Also have issues in installing onnx and onnxsim modules with this image.

Can someone help me on this.

Try

$ python3
>>> import tensorrt as trt
>>> trt.__version__
'8.0.1.6'

with the image tensorrt doesnt work. It says could not find the module tensorrt.

@AINacster,

Just flashed a new SD card with the original image. There is nothing wrong with TensorRT.
Please check the command below. You should have the same output.

Iam using YoloV8 model for detection/inference. This requires python 3.8 and in Python3.8 if I call for Tensorrt it does not appear. It gives error saying tensorrt not found.

With 3.6 it works fine. It shows TensorRT 8.0.0.1

Let me know if I am not clear. Thanks.

That's clear now.
Probably, you have installed Python 3.8 along Python 3.6.
That's the root of all evil. Two Python versions is screaming for issue you facing now.
Better to use the Jetson Nano Ubuntu 20.04 version with a native Python 3.8 on board.

I have used QEngineering 20.04 image. It comes with native Python 3.8 on board. I did install Python 3.8.
We should look at building appropriate TensortRT version with this image.
I also want to install ONNX and ONNXSIM on it. Confronted lot of issues with version.
Maybe one complete list of all packages can be great.
