No GPU temperature when running jtop inside a docker container

[livneros-greeneye]

Describe the bug

While running jtop inside a docker container, the GPU temperature details are offline.

To Reproduce

Steps to reproduce the behavior:

from jtop import jtop
jetson = jtop()
jetson.start()
jetson.temperature["GPU"]

1. Running the following commands on my host plots:
   > {'temp': -256.0, 'online': False}
2. Running a docker container, as mentioned in the documentation:
   docker run --rm -it -v /run/jtop.sock:/run/jtop.sock rbonghi/jetson_stats:latest plots:
   > {'temp': 39.875, 'online': True}

The same issue happens while using jtop:

1. On host:
   
2. Inside the docker container:

I've encountered the same issue as well, but it's intermittent.

I have kept the detail by log.

It's weird. The value in actual file is minus.

Hi @balabala65535

I apologize for this huge delay in replying.
The GPU output you read from jtop is exactly what you notice from the NVIDIA output in devices/virtual/thermal.
With Jetpack 5 and Jetpack 6, when the GPU is not working also, the GPU output is equivalent to -256, which in jtop is "Offline".

The GPU output on your host and on your docker must be the same. The Jtop service reads this output one time and provides for every Jtop client the same value.

I updated jtop for the latest version of Jetpack 6.0

sudo pip3 install -U jetson-stats
