Iohub issues in OS X 10.10.5

Coding
1

I am trying to use iohub to communicate with Tobii eye tracker in OS X.

Unfortunately, during trial-and-error, I found that iohub itself doesn’t work properly.
Delaytest demo also shows an error message.
( I tried to go accessibility, and allow app to control the computer, but it didn’t work at all.)

“raise RuntimeError(“Error starting ioHub server: %s”%(self.iohub_status))”

I also tested iohub selectTracker in other computer with TOBII SDK 3.1.0, and got below error. PsychoPy 1.84.1, and OSX 10.7.8.

and tested different machine with 10.9, and got same error…

Yes, I see this error too for the iohubDelayTest demo. Actually I don’t have the issue with importing tables but I get:

I don’t get an error running simple.py demo for iohub.

Hopefully @sol can shed some light or it will be slower for me to dig around.

When I install macports,python through macports, and compile psychopy and put it to site-packages directory in macports implemented python, the iohub eye tracker selecting example works properly : )

I think the problem comes from SDK dylib, since it referencing absolute path of python, and trying to execute it, in standalone version of Psychopy.

I have been in trouble with the same problem.
I tested several standalone versions (1.83.04, 1.84.02, 1.85.1) on OS X 10.9 to 10.12, but none of the combinations worked well.
There are no problems with Windows versions.

I hope it will be resolved asap.
