visionegg's Introduction
Welcome to the Vision Egg! INSTALLATION To install from source, type this from a command line (as root, if necessary) from the Vision Egg base directory: python setup.py install However, the above assumes all of the prerequisites are working. For blow-by-blow accounts of how I got the prerequisites for the Vision Egg installed on all the supported platforms, check out the website at http://www.visionegg.org/ RUN THE CONFIGURATION CHECK (BEFORE AND/OR AFTER INSTALLATION) Check for pre-requisites on your system by running check-config.py. This can be run before or after installation of the Vision Egg, and also displays useful information about the Vision Egg, if already installed. DEMOS, DOCUMENTATION, ETC. The demos are no longer installed, but they are included with the source code and the demo packages. See the README-DEMOS.txt file in those packages.

Broken import statements make VisionEgg/Textures.py unusable.
The following lines in VisionEgg/Textures.py break the module.
# These modules are part of PIL and get loaded as needed by Image.
# They are listed here so that Gordon McMillan's Installer properly
# locates them. You will not hurt anything other than your ability to
# make executables using Intaller if you remove these lines.

I have python-imaging and PIL installed.
numpy.oldnumeric no longer exists
Project attempts to import the oldnumeric module from numpy, but numpy has dropped that module. So users either have to use old version of numpy, or not use visionegg.
no Windows binary release for Python 2.6
There is no VE binary available for download for Python 2.6 on Windows.
This is because PyOpenGL 3.0.0 has bug on Windows. Specifically, multitexturing is broken, as reported (SourceForge bug 2817196). This is evident when trying to use the Gabor stimuli, which will fail and an exception will be raised. The workaround is to continue using PyOpenGL 2.x, which unfortunately not available for Python 2.6.
Installing in newer Macs
Hello!
I am having a real hard time installing in my Mac, Bigsur 11.6.4.
I am trying to set up a conda environment with older version of python, but even installing the recommended versions of pygame, PIL, etc.. has been a bit challenging.
Could you please help me?
Thank you so much.
Best,
Guilherme
VisionEgg randomly freezes on startup in Ubuntu 14.04.2
On my desktop running 14.04, when I run the following script:
https://github.com/florisvb/flydra_trigger/blob/master/nodes/simple_grating_test.py
A window opens, and more often than not, simply shows a transparent window frame. Occasionally, however, it does work and the stimulus (a moving sine grating) does play. The print out to the screen is identical whether or not the stimulus gets played:
$ python ./simple_grating_test.py
2015-05-29 11:29:18,342 (11822) INFO: Script ./simple_grating_test.py started Vision Egg 1.2.1+git with process id 11822.
2015-05-29 11:29:18,617 (11822) INFO: Requesting window 1280 x 720 24 bpp (8 8 8 0 RGBA).
2015-05-29 11:29:18,870 (11822) INFO: OpenGL 4.4.0 NVIDIA 331.113, GeForce GT 740/PCIe/SSE2, NVIDIA Corporation (PyOpenGL 3.0.2)
2015-05-29 11:29:18,870 (11822) INFO: Video system reports 32 bpp (8 8 8 0 RGBA).
I have not experienced this problem running the same script on ubuntu 12.04 (but on a different computer).
Any suggestions?
Python 2.6.3 build_ext bug breaks building the VE
When trying to build the VE with Python 2.6.3, we get the following traceback. This is known to the Python developers as Python bug 7064. This was fixed in Python r75256 and should hopefully be released as Python 2.6.4 in a couple of weeks.

FixationCross breaks OpenGL state
Drawing the FixationCross stimulus causes problems when drawing other stimuli types. In particular, the other stimuli fail to be drawn.
