Hi,

there seems to be a general issue with PsychoPy 1.80.00rc1 on Windows XP (SP3), which even occurs when running one of the bundled demo experiments without making any changes. Right after entering the experimental info, the experiment (in this case the Stroop demo) terminates with the following error message:

#-----------------------------------------------------------------

Running: C:\Dokumente und Einstellungen\admin\Desktop\psychopy180demos\stroop\stroop_lastrun.py

Error in framebuffer activation

AttributeError: Window instance has no attribute '_progFBOtoFrame'

#-----------------------------------------------------------------

I was able to reproduce the problem on two separate Windows XP machines (PsychoPy 1.79.01 worked fine on these). I don't know if other Windows versions are affected as well. On OS X (10.8.5), the issue does not seem to be present.

Please let me know if you need any additional information.

Thanks!

Bjoern

PS: Is there really no way to copy the error messages from the PsychoPy output window? I wound up taking a screenshot of the window and then running OCR on the image to extract the text. That did not exactly strike me as elegant... :)

Thanks for the speedy bug report (although 1.80 is available I haven't yet 'announced' it)
I think the graphics cards on these XP machines aren't as advanced as on the Mac?

Could you test a fix for me? Drill down into the psychopy files and find something like
    ...Lib/site-packages/psychopy/visual/window.py
Could you find line 1213 and change it from
        if self.useFBO and not GL.gl_info.have_extension('GL_EXT_framebuffer_object'):
to read
        if self.useFBO and not self._haveShaders or not GL.gl_info.have_extension('GL_EXT_framebuffer_object'):

Hopefully that will fix it? If not could you run the demo script called sysInfo.py and send us the output from that so I can see what your card does/doesn't support.

You should be able to copy from the output window by right-clicking. Yes, Ctrl-C might not work from that panel I think

cheers
Jon

Thanks for the quick reply, Jon.

After I changed window.py per your instructions, I got the following error message:

#-----------------------------------------------------------------

Running: C:\Dokumente und Einstellungen\admin\Desktop\psychopy180demos\stroop\stroop_lastrun.py

Traceback (most recent call last):

File "C:\Programme\PsychoPy2\lib\site-packages\psychopy-1.80.00-py2.7.egg\psychopy\visual\window.py", line 1213, in _setupPyglet

if self.useFBO and not self._haveShaders or not GL.gl_info.have_extension('GL_EXT_framebuffer_object'):

AttributeError: Window instance has no attribute '_haveShaders'

Exception AttributeError: "Window instance has no attribute 'frameTexture'" in <bound method Window.__del__ of <psychopy.visual.window.Window instance at 0x0DB1E4B8>> ignored

#-----------------------------------------------------------------

So apparently "_haveShaders" is not a known attribute on that system either. I then removed the problematic if statement in line 1213 completely and unindented the next two lines accordingly. After I did that, the experiment ran without a hitch.

You are right, the Windows laptops (including their graphic chips) are indeed not as powerful as the Mac I used, but we have plenty of similar ones lying around and they still work well for experiments that are not too computationally/visually demanding. Sorry for assuming it was a general XP issue, I deliberately did the tests on two distinct laptop models to rule out the possibility that the issue was caused by idiosyncrasies of a single machine.

Here is the output from sysInfo.py from one of the Windows machines:

Finally, a quick note on copying text from the "PsychoPy output" window:

On my Windows machine, I cannot select text in that window using the mouse or <cmd><a>. The text area simply looks and behaves like a rendered image, rather than a text field... that is, unless I move the mouse cursor to the very bottom of the text area. Then it changes from an arrow to the text selection cursor and I can drag the text selection upwards or select the text using <cmd><a> (and then copy the text to the clipboard). Weird. But I am glad that I now know what to do in order to not have to jump through that awkward screenshot-OCR-hoop anymore.

The output window also behaves a little strange when you increase its size (this might be related to the above issue): the white text area does not get bigger and instead the additional area of the window is filled with a grey background. I've attached a screenshot depicting this phenomenon.

Again, thanks a lot and please let me know if I can be of any further help.

I received a similar error trying to run any .psyexp file on a mac running OSX 10.6.8. Clicking run button takes one to a blank white screen. After pressing esc, console shows "error in framebuffer activation." 1.79.01 works fine.

Brian, could you also try to run the sysInfo.py demo?
For Bjoern that gave me the info I needed to be able to fix the issue (his graphics card supports framebuffers but not floating point textures, whereas I assumed that the two things went together).

I'll be releasing a 1.80.01 early next week with these minor tweaks fixed.

Hi,

I seem to be having the exact same problem as Bjoern. I'm running Psychopy on an older MacBook (mid 2006 or 2007 I believe). The hardware may not be top of the notch anymore but it suffices for not too demanding experiments so I hope it can be fixed.

Here's my sysInfo output:
