What specifically went wrong when you tried that?:

I fixed my problem. I installed the 1.4.1 version of pyglet. I deleted it and installed the 1.3.2 version which solved the problem

I am having the same problem (on a different OS) but downgrading to pyglet 1.3.2 did not help.

OS: Windows 10 Enterprise
PsychoPy version: 3.2.4

I installed PsychoPy via Anaconda as described here.

When I start the Builder and try to run an experiment, I get the following error message:

Traceback (most recent call last):

After I downgraded to pyglet 1.3.2, I got the following error message:

Can anybody help with this problem?

Thanks in advance,
Guido

PS: I also get these warnings, which I guess are not the root of the problem:

maybe @dvbridges has an idea what to do about the problem?

5

That’s definitely a bug in PsychoPy itself. @jon hadn’t you been working on pyglet 1.4 text alignment for quite a while?

@Guido_Biele I think the issue ultimately comes down to having a very old graphics card or, more likely, a poor driver. It appears that your graphics card/driver doesn’t support opengl shaders, but most likely you’re using the windows provided driver and you could alternatively install the appropriate driver for your particular card (nvidia, intel, AMD).

The error from the original post comes from an incompatibility PsychoPy had with Pyglet v1.4.x which I have fixed in the current repository (although there are some further issues around the layout not being identical with default settings). The continued error after downgrading to 1.3.2 is caused by poor drivers

7

Oh, so these fixes have not been released yet. My bad :slight_smile:

8

Actually I just checked and Pyglet 1.4 was supported (to a degree) in v3.2 but support hadn’t been added at that stage for machines that didn’t support shaders (as in this user’s case) and that’s something that I’ve fixed as well as providing a (somewhat) more consistent alignment setting with the old system.

Thanks everyone for looking into this!

Is it sure that this is a graphics card/driver problem?
The machine is rather new, but it has a XEON processor and no extra graphics card.*
I can’t find out what driver is installed, because the system is “locked down”, which is also the reason why I installed PsychoPy via Anaconda.

The reason I am not sure that this is a hardware/driver problem is that a while ago I had the same problem, but then I could install the stand-alone version, which worked fine. (Unfortunately I can’t install the stand-alone version on the machine I used daily at work.)

Best, Guido

* This machine (which is not what we are running experiments on, but its the machine at my desk)

  • Precision 7820 Tower
  • PROCESSOR: Intel Xeon Gold 6134 3,2 GHz, 3,7 GHz Turbo
  • no extra graphics card

OK, it might actually be the driver.
it looks as if my machine has intel’s basic display adapter, which might need updated driver to work with openGL.

However, this would not explain why on my other machine PsychoPy installed via anaconda would not start an experiment due to the pyglet (1.4.9) error, but would work just fine with PsychoPy installed in its stand-alone version.
