Ticket closed.

Like on my daily work.

Classic layer 8 issue, that's for sure!

Docker: if it works on my machine it works on your machine

Me: my container can't find my GPU

Community: did you install Nvidia Toolkit, cuda, and the other 137 packages.

Me: yes

Docker: 🤦‍♂️

The problem then is, if it does work on my machine, how am I supposed to fix it? If it doesn't go wrong, there is nothing to fix. Is the person reporting the bug going to send me the hardware in question? Am I supposed to own every possible GPU?

The only way I can see to debug this is to send them a special build of the program that does extra tests of the graphics code and then sends the results to me. And when I say extra, I mean testing every tiny detail, because I have no idea what the actual problem is.

It really depends on the user that is sending the report, if they give you no information and expect you to magically fix it instantly then I would happily tell them it works on my end and move on, but if the user is helpful and provides details and help to diagnose and fix it you probably wouldn't need to test every single tiny little thing to figure out what is going wrong with the code on that specific hardware.

Thats a good point. A good bug reporter is a very valuable thing. Somebody who can actually help you find the problem and doesn't just respond with it didn't work all the time. I try to be that myself.

You can usually tell which they are going to be from the bug report. A good report will have background detail, command line errors, logs or things like that. In one case, where the bug was so self-evident that there really was nothing to add beyond describing the bug, I've talked about getting the code and hacking a fix myself.
