Killing all Python processes that are using either of the GPUs

I have the following and I don't want to enter the PID of each Python process that uses either of GPUs one by one. How can I do so?

Update: I used both killall and killall python3.8 and none worked:

$ killall -9 python3.8

Here, SIGKILL (9) will force it to exit.
