baseplatform.py problem

[Bruce Weaver]

Hello group. I'm a newcomer to PsychoPy, and have run into a problem
when I run the Monitor Center tool. Here's the output (my apologies
if there is any nasty line-wrap):

Welcome to the Integrated Development Environment (IDE) for PsychoPy!

Any thoughts on what to do about this? Is there a more recent version
of baseplatform.py I need to download? Any hints gratefully
received!

Cheers,
Bruce

p.s. - I have a Lenova ThinkPad running XP-Professional, and sitting
in a docking station, in case that matters.

No this one is new to me. Have you got anything to work at all? Are you able to run the sys_info demo? If you can get that to run then please send us the output, so we can see more what is installed and what  drivers you have loaded.

thanks,
Jon

Hi Jon. OK...here is the output from sys_info:

Looks like there is some problem with calibTools.py.

Actually, I'm wondering if you have all the dependencies/drivers properly installed. This message suggests that scipy hasn't been installed fully (or that you are using a different version to the ones I've tested on). Do you know which version you installed?

The previous post might result from no OpenGL drivers. Have you fetched the latest drivers for you graphics card?

Jon

[Bruce Weaver]

Line-wrap isn't working properly in this window, so
I'll insert hard returns and hope it all works out!

Yes, I did update the drivers. But maybe the video card is
inadequate.
It's the Mobile Intel(R) 965 Express Chipset. The system info
output shows two of them, actually.

Thanks Jon.

Well, it's a puzzle. That looks like the right package, and scipy documentation shows no sign that optimize has moved as a sub-package. That command has worked before and should still work. I could change calibtools so that it silently ignores errors there and just warns you that gamma calibrations won't be possible.
http://psychopy.googlecode.com/svn/trunk/monitors/calibTools.py

None of this addresses the previous opengl error you were getting - i still don't understand that one. I have run psychopy off a winXP machine with that chipset and it did work (maybe with a pyglet window instead of pygame, though).

For sure integrated Intel graphics are far from ideal - for one thing they don't allow syncing to the vertical blank, so frame rates are not precisely timed. Generally not suitable for experiments. But they should work to some extent.

OK, I've now figured out the source of the second problem I ran into
(i.e., ImportError: No module named scipy.optimize). I did download
the scipy installer, but it seems I then failed to run it. D'oh!!
Now that I've actually installed scipy, I no longer get that error.
(Yes, I am hanging my head in shame.)

However, all is not well, because now everything grinds to a halt when
I encounter the same problem as before (when trying to run the Monitor
Center tool). Here's my current output from sysInfo.py:

Welcome to the Integrated Development Environment (IDE) for PsychoPy!

So...back to where we started!

I received this from a friend who uses Python:

--- start of message ---

This is an error in the last file mentioned in the traceback:

C:\Python25\Lib\site-packages\OpenGL\platform\baseplatform.py"

line 106, in constructFunction
> func.__doc__ = doc
> UnboundLocalError: local variable 'func' referenced before assignment
>

The error actually occurs in the if/else constructs between lines
93-97
where one of the AttributeError lines is missing the 'raise' cmd. If
you
add in the missing 'raise' and save the file it should now work.
Before
running a demo you should delete the pre-existing compiled version of
this file 'baseplatform.pyc'. A new one will be created when
baseplatform.py is next used.

--- end of message ---

As he says, "raise" was missing from line 94 in my baseplatform.py
file. When I added it, everything worked. So my output from sysInfo
now looks like this:

The Monitor Center tool now runs too.

So...thanks for your help Jon.

[Jonathan Peirce]

Good info bruce, thanks.

Again, though, just beware that those chips don't seem to support frame sync-ing under windows, so are not a good option where timing is important. On OS X the driver support seems better, they just aren't super-fast.

best wishes,
Jon

This is the first time I've needed to use jpg image displays, and I'm
getting this error even from the face_jpg.py demo, and I can't seem to
get around it:
configured pyglet screen 0

I can't get any PatchStim objects to work in my own code.
I'm running on an IBM thinkpad with XP
Python 2.4, Psychopy .96.01

I have a presentation at 4pm GMT on Tuesday where I'm hoping to make
psychopy shine, with pictures (256x256 jpg's) displayed along with
sounds and text.

Any suggestions?
Thanks!
