Running on azure linux - bails

After running into an issue running locally on a mac book pro

(
Exception AttributeError: “‘Window’ object has no attribute ‘useNativeGamma’” in <bound method Window.del of <psychopy.visual.window.Window object at 0x7faf255a7c10>> ignored
}
)

I spun up and ubuntu azure instance and after installing some missing python dependencies after an apt install of psychopy, I have the same error (as above)

I actually have no idea what graphics support my azure instance has. I just took the default mid power machine. Is there some way I can get psychopy to check if my graphics support is sufficient? It seems a drag not to be able to run in the cloud if this really is a dependency on a local openGL card.

Seems it has opengl…

I think this error can sometimes be misleading, as it can be caused by trying to close the window gracefully after encountering another error. What was the full traceback?

Looks like it is with the pyglet library - might be related to this issue. If appropriate, you could try installing pygame and setting winType="pygame" when opening the window; that works for me over a remote connection.

Basically, pyglet (which is a lib we use but didn’t create) can’t create a window and you’d have to work out why that is from the pyglet developers. It looks liks your azure system doesn’t provide an appropriate configuration. In particular, looking at your glxinfo output, the fact that it says “direct rendering: No” suggests to me that something isn’t complete about the opengl options on your system. So that might well be the source of the problem.

I don’t know much about azure but in general virtual machines are a bad way to run PsychoPy. Even if they work (they often don’t because they don’t have the appropriate hardware access) they will always have a performance hit compared with a native machine.

It seems a drag not to be able to run in the cloud if this really is a dependency on a local openGL card.

We’ve always relied on native calls to OpenGL drivers. Sorry but that’s how we get the performance we need. The reason that we can now move to an online system without dramatic loss in performance is precisely because WebGL now allows us to to write similar calls in a web page. But that’s a totally different concept to what you’re trying here. Not sure if I understood your comment correctly.
