ENH/DOC: improve dependency documentation across OS

[dengemann]

Currently ioHub depends on recent versions of gevent. For example Ubuntu 12.0.4 LTS comes with gevent 13.6 which will not work with current ioHub code (seems to require 13.8 -- DatagramServer). However compilation from github master seems to have worked for me. Note: also a timely versions of greenlet is required. Anyways, would be good to handle these dependencies.

[dengemann]

... and related: it would be good to create a list of dependencies for Linux systems ....

Hi Denis,

I thought Gevent 1.0 was required actually, anything using the older
libevent (gevent 0.x.x series) did not work. Maybe in 0.13.8 DatagramServer
was back ported from 1.0?

Anyways, would be good to handle these dependencies.

Sorry, can you be more explicit? On Linux all the required dependencies for
psychopy and iohub need to be installed manually. I 'think' this list is
still up to date:

Thanks again,

Sol

Looks like some of the links on the install page for linux are now dead
actually, so I need to fix that when I get a chance.

Thanks,

Sol

@isolver don't worry, I'm almost having a running setup on Linux. I'll update the issue as soon as I'm done here. Then we can see what can be added to the docs.

... Tracker is connected but I get some weid pyglet error.

@isolver fasscinating. the WrapWidth argument in calibration graphics causes a bad low level crash on Linux with the most recent pyglet version ...
This line:
File "/usr/local/lib/python2.7/dist-packages/PsychoPy-1.78.01-py2.7.egg/psychopy/iohub/devices/eyetracker/hw/tobii/tobiiCalibrationGraphics.py", line 208, in _createStim\n wrapWidth=self.width*0.9)\n'

Shall we add a fix (trying to set wrapwidth) in Psychopy or here?

[isolver]

For pyglet, I would suggest using the 1.1.4 stable version, not 1.2. 1.2
seems to actually be somewhat slower at rendering than 1.1.4.

http://www.pyglet.org/download.html

You should not have an issue using 1.1.4, if you do, let me know what it is.

Thanks again,

Sol

looks like you also need to get Xfixes; it came with the Mint Linux distro
I use but maybe not with the distro you are using?

Thanks again,

Hey Sol,
the issue actually was with 1.14.
I was thinking about about a function that checks for OS / versions and safely adds the text stim params using a try / catch.

Btw. good news: with my temporary hack all is working nicely. I'll wrap up my experience so we can add new examples + docs

[dengemann]

@isolver updated the title to match our actual discussion.

[isolver]

excellent. ;) The TextStim fix should likely be implemented in
psychopy.visual, which keeps a flag relarding the pyglet version being used
already for some other 1.1.4 vs 1.2 conditional logic.

Can this be closed? Not sure / clear what the outstanding issue(s) here are.
