[solved] All pygaze examples doesn't work for different reasons. UPDATE: Same underlying issue

rrrrrr
edited September 2015 in PyGaze

Hello,

This question relates my previous discussion "Pygaze example doesn't work."

I tested all four examples except for "show_webcam" in my MacPC (OS10.9.5) using Python2.7.10 and Eyelink1000plus.
All examples got different errors, so I couldn't have checked whether I use Pygaze.

"annoying_message" got a fatal Python error. "simple_experiment" had a error in libscreen.py. "shooting_game" and "simple_tracker_experiment" had a same error in "libeyelink.py".

Here are error messages below. What caused them?

◯ annoying_message

    Hello,

    I was able to fix my error.

    Please look at 'Pygaze example doesn't work' (http://www.cogsci.nl/forum/index.php?p=/discussion/1597/open-pygaze-example-doesn039t-work-#Item_6).

    I hope for your information.

    Hi @rrr,

    Sorry for the late reply, I've been away for a bit. From the thread you link I understand that you've solved all the above issues? For future reference, I'm copying your solution from there into this thread:

    Thank you for your advise. I have good news. I succeeded to use Pygaze in Mac. I found that we should install the EyeLink Developer's Kit (https://www.sr-support.com/showthread.php?15-EyeLink-Developers-Kit-for-Mac-OS-X-(Mac-OS-X-Display-Software)). This will be installed in '/Application/'. We can chose the suitable version of pylink for our Python (e.g. pylink2.7) from '/Application/Eyelink/pylink/'. After the choice, we should copy it to the directory we usually use (in my case, opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7). Don't forget to rename it from 'pylink2.7' to 'pylink', and create the path between your Python and the directory includes pylink.

    Thanks for figuring this out!

    Edwin
