Hi,
I am having problems using/instalation the Deepstrem application on the Jetson Xavier NX.
I have installed a fresh version of JetPack 4.5.1 via SDK Manager. I have performed an update and system upgrade. I then proceeded to install deepstream following the guide on the Nvidia website “Jetson setup”:
https://docs.nvidia.com/metropolis/deepstream/dev-guide/text/DS_Quickstart.html
In the next step I proceeded to install Deepstream-python according to this guide:
https://docs.nvidia.com/metropolis/deepstream/dev-guide/text/DS_Python_Sample_Apps.html
When trying to run the application: deepstream_test_1_usb.py
I get the message:
streammux.set_property('width', 1920)
AttributeError: 'NoneType' object has no attribute 'set_property
and before:
Unable to create pgie
Based on information found on this forum I used the command to check the installation of gst-inspect: gst-inspect-1.0 -b
jetson@jetson-desktop:~$ gst-inspect-1.0 -b

Blacklisted files:
libnvdsgst_infer.so
libnvdsgst_osd.so
libnvdsgst_inferaudio.so
libnvdsgst_inferserver.so
Total count: 4 blacklisted files
After checking the path to the missing files, those files exist in this folder.
I also tried deleting the cache files with the command:
rm -rf ${HOME}/.cache/gstreamer-1.0
and run the gst-inspect command again, but again the files are not found.
With Deepstrem I tried two installation methods using tar package ( deepstream_sdk_v5.1.0_jetson.tbz2) and Debian package ( deepstream-5.1_5.1.0-1_arm64.deb).
The effect is the same.
I also tried to load system using ready made system image which I burned to SD card. Also the effect is the same.
Earlier I was running Deepstream 5.1 on Jetson Nano also on JetPack 4.5.1 and I didn’t have such problems, everything ran fine and worked fine.
I checked these links:
- concerns RTX: Deepstream python apps deepstream-test1 unable to create source - #8 by coolbot
- Deepstream EXE
Unfortunately I still don’t know how to deal with this problem.
