Killing all Python processes that are using either of the GPUs

gb flag
Mona Jalal

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:

One of the reasons I like `killall` but I don't really understand your question as are you trying to kill gnome-shell too? (you've listed it)

What command gives you that output? Which of those processes do you want to kill?

the point is exactly not to kill gnome-shell and only kill python processes without entering their PIDs @guiverc

As I stated in first commend; I'd use `killall` or `killall python3.8` in that example. Use `man killall` to read your options (which are many, including using patterns). As I don't know what your paste was I don't know if you'll need to adjust the command

Sorry I don't know what the `nvidia-smi` shows and currently used boxes are all AMD so I can't explore what it likely is.. so cannot help with how to interpret what it's actually showing and thus the required option you'll need (answer may only be path is also need `/usr/bin/python3.8` for example; but I don't know `nvidia-smi` sorry; I'd use `ps` myself.

$ killall -9 python3.8

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

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
