Compatibility of Jetpack-Stats and Jetpack

Issue Overview

Users of the NVIDIA Jetson Orin Nano Developer Kit are encountering an issue where the jetson_release command reports a message indicating that Jetpack is missing, despite having it installed. The specific error message states:

Software part of jetson-stats 4.2.3 - (c) 2023, Raffaello Bonghi
Jetpack missing!

This occurs while the user attempts to run jetson-stats, which is a tool for monitoring system performance. The context of this issue arises when users are trying to utilize jetson-stats version 4.2.3 with Jetpack version 6.0 on L4T 36.2.0 and Ubuntu 22.04 (Jammy Jellyfish). The problem seems to be consistent among users, indicating that it is not an isolated incident.

The impact of this issue significantly affects the user experience as it prevents access to system monitoring capabilities, which are essential for performance tuning and debugging applications running on the Jetson platform.

Possible Causes

1. Software Incompatibility: The version of jetson-stats (4.2.3) may not be compatible with Jetpack 6.0, leading to the reported error.

   • The developer has indicated plans to update jetson-stats to support Jetpack 6.0, suggesting that this could be a primary cause.

2. Configuration Errors: Incorrect configurations during installation or setup may lead to the software not recognizing the installed Jetpack.

   • Users may have missed certain steps in the setup process that are critical for proper integration.

3. Driver Issues: Outdated or incompatible drivers could prevent jetson-stats from functioning correctly.

   • Ensuring all drivers are up-to-date is crucial for compatibility with newer software versions.

4. User Errors: Misconfigurations by users during installation or updates may result in the software not functioning as intended.

   • Users need to follow installation guidelines meticulously to avoid such issues.

Troubleshooting Steps, Solutions & Fixes

1. Verify Installation:

   • Check if Jetpack is correctly installed by running:

     dpkg -l | grep nvidia-jetpack
     

   • Ensure that the output confirms the installation of the correct version.

2. Update jetson-stats:

   • If you are using an older version of jetson-stats, update it to a newer version that supports Jetpack 6.0:

     sudo pip3 install -U jetson-stats
     

   • Users reported success with version 4.2.4, which includes support for Jetpack 6.

3. Check Dependencies:

   • Ensure all necessary dependencies for jetson-stats are installed:

     sudo apt-get install nvidia-jetpack-runtime nvidia-jetpack-dev
     

4. Reinstall Jetpack:

   • If issues persist, consider reinstalling Jetpack using the NVIDIA SDK Manager:
     1. Open NVIDIA SDK Manager.
     2. Select your device and choose the appropriate Jetpack version.
     3. Follow the prompts to reinstall.

5. Monitor Logs for Errors:

   • Review system logs for any related error messages that could provide more context:

     dmesg | grep jetson
     

6. Use Alternative Monitoring Tools:

   • If jetson-stats continues to fail, consider using alternative tools temporarily until compatibility is confirmed.

7. Contact Support or Community Forums:

   • If none of these solutions resolve the issue, consider reaching out on NVIDIA Developer Forums or checking GitHub repositories for any ongoing discussions regarding this issue.

8. Best Practices:

   • Always ensure your system is updated before installing new software.
   • Regularly check for updates from both NVIDIA and community developers regarding compatibility issues.

By following these steps, users should be able to diagnose and potentially resolve the issues they are experiencing with jetson-stats and Jetpack compatibility on their NVIDIA Jetson Orin Nano Developer Kit. Further investigation may still be required if problems persist after these troubleshooting efforts, particularly concerning software updates from developers like Raffaello Bonghi regarding jetson-stats.
