Doesn't work on Ubuntu 20.04.1

[thedanyes]

Seems like some kind of problem with the GPU portion? I have Ubuntu 20.04.1 with NVIDIA 450.66, Python 3.8.2.

~/Downloads/sysmon/src$ python3 sysmon.py 

Traceback (most recent call last):
  File "sysmon.py", line 595, in <module>
    main()
  File "sysmon.py", line 589, in main
    main = MainWindow()
  File "sysmon.py", line 217, in __init__
    self.update_gpuinfo()
  File "sysmon.py", line 526, in update_gpuinfo
    num = data[gpu_ind][4]
IndexError: list index out of range

GPU hardware is GTX 780.

Here's a screenshot of nvidia-smi output if that helps:

Not sure yet where to problem is. Could you please post the output of nvidia-smi dmon -c 1

[thedanyes]

~$ nvidia-smi dmon -c 1
Not supported on the device(s)
Failed to process command line 

[MatthiasSchinzel]

So here we have the problem. I don't know why nvidia-smi failed here, maybe nvidia does not support this functionality for this model.
However there is still hope we can get that information from a different command. Please post the output of nvidia-smi -q. If that does not work I am afraid we have to disable your GPU statistics in the tool in this case. :/

Btw, I think this problem is not depending on Ubuntu 20.04.1.

i am having the same issue, so i will post the output here since i can't run it too

    Decoder                     : N/A

The only thing we can get in your case is the memory load :(

FB Memory Usage
    Total                       : 962 MiB

    Free                        : 507 MiB

Maybe better than nothing, but not really satisfying in my opinion. But for the GPU we have to use nvidia-smi.

However, I am still interested in brown-d output, to see if nvidia-smi behaves the same in his case.

~$ nvidia-smi -q

Also I found this in 'man nvidia-smi':

The "nvidia-smi dmon" command-line is used to monitor one or more GPUs (up to 4 devices) plugged into the system. [...] The output data per line is limited by the terminal size. It is supported on Tesla, GRID, Quadro and limited GeForce products for Kepler or newer GPUs.

I am also having issues on OS: Ubuntu 20.04.1 LTS x86_64 no nvidia, Lenovo Carbon X1.

Are we any further with this issue, I encountered it also.

[Mekk]

I faced the same problem (GeForce GT 710 in my case, nvidia-smi dmon fails with Not supported on the device(s)).

IMHO it doesn't make sense to classify supported and unsupported cards. Simple logic „if nvidia-smi fails, disable GPU stats” would do…

Quick&dirty patch in sysmon.py:

    def update_gpuinfo(self,):
        self.gpuinfo = np.roll(self.gpuinfo, -1, axis=0)
        data = self.s.get_nvidia_smi_info()
        if not len(data[0]) >= 4:
            return

(I added two last lines) and sysmon starts. Of course GeForce tab doesn't show any data. It would be nicer to hide this tab in such a case of course.
