If jtop/jetson-stats stops working after updating JetPack/L4T, it’s often because the version you have installed on the Jetson is not updated with the newest L4T → JetPack mappings.
The latest jetson_stats repository already contains the updated mapping file, but the version you installed (apt/pip/old package) may still be behind.
So the fix is simple: grab the newest jetson_variables.py from the official repo, replace your local file, reboot, and jtop works again.
1) Download the latest jetson_variables.py from the official repo
-
Open your browser on the Jetson.
-
Go to the official
jetson_statsGitHub repository. -
Navigate to:
jtop→core→jetson_variables.py -
Open the file and download/save the raw file (or copy its full contents).
You now have the latest version of jetson_variables.py from the repo.
2) Open your installed file.
- Open the file you showed earlier:
.../jtop/core/jetson_variables.py
Common location (varies by install method, but this is typical):
/usr/local/lib/python3.x/dist-packages/jtop/core/jetson_variables.py
3) Replace the file content with the latest one
-
Open the downloaded latest
jetson_variables.py -
Copy all contents
-
Paste into your installed
jetson_variables.py(replace everything) -
Save
5) Reboot
Reboot the Jetson
jtop reads JetPack/L4T info using a version-mapping table inside jetson_variables.py.
When JetPack updates, older installed builds may not recognize the new version numbers. The latest GitHub file includes the updated mappings, but your installed package might not.

Replacing jetson_variables.py updates those mappings immediately.
I hope this works for you all :)
