attempt to get argmax of an empty sequence

[semel1]

Upon running "main_IRT.py", got an error:

Exception has occurred: ValueError
attempt to get argmax of an empty sequence
  File "D:\colorization\deep-video-prior-master-pytorch\main_IRT.py", line 49, in <module>
    for x in subprocess.Popen("nvidia-smi -q -d Memory | grep -A4 GPU | grep Free", shell=True, stdout=subprocess.PIPE).stdout.readlines()]))

Happened in both Windows 10 and WSL2 Nvidia RTX 3090

I fixed this issue by changing the first grep command, resulting in this:

"nvidia-smi -q -d Memory | grep -A5 GPU | grep Free"

Edit: Apparently in my case the nvidia-smi command gives one more row of information so the 'Free' row is left out

This is the output when using this command nvidia-smi -q -d Memory | grep -A5 GPU:
