Your topic will be best served in the Jetson category.

I will move this over for visibility.



Could you check the PyTorch version and share it with us?

>>> import torch
>>> torch.__version__

If it is not our prebuilt (with nv tag), please install it with the following instructions:


I have torch version 2.1.0a0+41361538.nv23.6
when running command
import torch
it shows True, and i install
torchvision 0.16.2
by following this steps PyTorch for Jetson
It works thanks for the support.
But still facing issue how to use deepstream and tensor RT for object detection.


Good to know PyTorch and TorchVision work on your environment now.
Please see the following for the examples of Deepstream and TensorRT.

Deepstream: GitHub - NVIDIA-AI-IOT/deepstream_python_apps: DeepStream SDK Python bindings and sample applications
TensorRT: TensorRT/samples/python/efficientdet at release/8.6 · NVIDIA/TensorRT · GitHub
