I was running the jupyter notebook fir the course: Building Video AI Applications at the Edge on Jetson Nano.
When I try to see the apps and stream using the ls command in jupyter, I am able to see them. But when I try running the deepstream app using this command:
Run the app
!cd $PYTHON_APPS/deepstream-test1-rtsp-out \ && python3 deepstream_test1_rtsp_out.py -i $STREAMS/sample_720p.h264
, I get this error:

Ok, this looks like an installation issue.
Let us check a few things.
Can you run
deepstream-test1-app successfully ?
Do you have the DeepStream Python binding library installed ?
And does your software version match ?
Thank you for responding to my doubt. Actually, the entire deepstream course is run on a docker container.And I am accessing the jupyter lab through this container itself. So I guess my version and compatibility might not be an issue. The instructions I followed to use the docker script were:
# create a reusable script
echo "sudo docker run --runtime nvidia -it --rm --network host \
-v /tmp/.X11-unix/:/tmp/.X11-unix \
-v /tmp/argus_socket:/tmp/argus_socket \
-v ~/my_apps:/dli/task/my_apps \
--device /dev/video0 \
nvcr.io/nvidia/dli/dli-nano-deepstream:v2.0.0-DS6.0.1 " > ds_docker_run.sh
# make the script executable
chmod +x ds_docker_run.sh
# run the script
I tried grep on the plugins and wasn’t able to find the decoder plugin installed while I was in the docker image.
Answering your questions:
NO, I am unable to run the
deepstream-test1-app since it gives the decoder error and the other errors follow depending on the pipeline.
No, I didn’t install anything else since I thought it was in the docker image and won’t need any additional installations.
Do you think it might be in the docker image that is causing the error since some plugins are missing from it?
Due to hardware limitations, some libraries are shared between Docker and host on Jetson.
You also need to install dependencies in the host. These include Jetpack and some other libraries
You can refer this documentation
since you are using the jetson nano, 6.0.1 is the highest version supported.
Thank you for the response. If that’s the case, then it can possibly be because I am using Jetson Orin NX. I will just follow the instructions from the jupyter lab and do it in the deepstream on my orin. Thank you for letting me know what the issue was.
