does not find tegrastats despite its installed

[ardupython]

tegrastats is installed under a custom user, which is also the main user running the program. Tegrastats is located in "/usr/sbin/tegrastats" and can be executed from the commandline as "tegrastats".

But the output of jtop only shows "Tegrastats is not availabe on this board".

• Does jtop use only the path defined in jtop.py or are there other paths defined else where?
• Is there an option to point it to the tegrastats path besides the TEGRASTATS variable in jtop.py ?

If the paths in the TEGRASTATS variable are changed, jtop crashes.

Changing the paths from

# List of available fan
    JTOP_FOLDER = '/opt/jetson_stats/'
    LIST_FANS = [('/sys/kernel/debug/tegra_fan/', False), ('/sys/devices/pwm-fan/', True)]
    TEGRASTATS = ['/usr/bin/tegrastats', '/home/nvidia/tegrastats']

to the current path

# List of available fan
    JTOP_FOLDER = '/opt/jetson_stats/'
    LIST_FANS = [('/sys/kernel/debug/tegra_fan/', False), ('/sys/devices/pwm-fan/', True)]
    TEGRASTATS = ['/usr/sbin/tegrastats']

crashes the program

Hi @ardupython ,

Thank you for your issue, but which board are you using? jtop automatically find the first tegrastats available in TEGRASTATS and is not require to modify the code :-)

• Does jtop use only the path defined in jtop.py or are there other paths defined else where?

Follow only the paths defined in jtop.py. Usually tegrastats, jetson_clocks and the fan are available only there when you use an NVIDIA Jetson

• Is there an option to point it to the tegrastats path besides the TEGRASTATS variable in jtop.py ?

At this time is not available. Do you have another distribution on your jetson?

[ardupython]

Thanks for the great software tool. I try to run it on ubuntu 16.04 on a nvidia TX2 Jetson board. Tegrastats is added to path and can be started directly from the command line, just "tegrastats" with or without sudo. If i use the default paths, which are defined in "jtop.py", tegrastats is not found. As mentioned above, its located in "/usr/sbin/tegrastats", which is not part of the standard paths in "jtop.py".

Are there maybe other environmental variables that could affect it?

With this different configuration I never tried, but without change the code you can try:

• restore jetson-stats code
• Move tegrastats to /usr/bin/tegrastats (It's also good to run tegrastats from command line, last new releases of jetpack have tegrastats and jetson_clock in this folder)

Are there maybe other environmental variables that could affect it?

No, should work fine

I see in your crash you are using this hostname

dist-pacuser@vm

Are you working on virtual machine? The name look like that
