crash

hey @rbonghi

From time to time I have this crash (not all the time that's the weird part) :

nvidia@tegra-ubuntu:~$ sudo jtop
[sudo] password for nvidia:
Traceback (most recent call last):

Hi @blitzvb ,

try to update jetson-stats with:

sudo -H pip install --no-cache-dir jetson-stats --upgrade

This bug is fixed from version 1.6.8, you should be have an older version installed.
Keep me posted if after this upgrade, you don't have this error.

Best,
Raffaello

PS: To know the version installed use: pip freeze | grep jetson-stats

[blitzvb]

the bug fixe is worst on my system ;)

pip3 freeze | grep jetson-stats
You are using pip version 8.1.1, however version 19.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

It's really really strange 😮 Look like is not well installed the new version of jetson-stats.

File "/usr/local/lib/python2.7/dist-packages/jtop/main.py", line 65, in signal_handler
tegra.close()
NameError: global name 'tegra' is not defined

About the issue referenced at the head, Do you read this error only when you close jtop with CTRL-C, right?

Anyway I will try to emulate on my NVIDIA Jetson tonight.

[blitzvb]

no it's all the time when I start jTop with the new version that I installed like that :

sudo -H pip install --no-cache-dir jetson-stats --upgrade

I can stay in that state (happy to help) or try to remove it and reinstall ?

[rbonghi]

First for all, thank you for your help, but yes, sure!
Remove and reinstall! :-)

[blitzvb]

removed and resinstalled.

I have an error that look the same. FYI, it's on Jetson Tx1 , I don't have nvpmodel.
