question: Selecting one gpu from cli
context: Hi, I have 4 gpus on my machine. I want to select the third one, that has index 2. How do I pass an argument from CLI?
  I call
  python 4_pretrain_encoder.py --gpus 2 --max_epochs 5
  but it runs one script on two gpus instead of the third.
answer: python 4_pretrain_encoder.py --gpus 2, --max_epochs 5
