  I forgot to add that I'm also running the 'normal' (i.e. the non WinPython) version along side, and this works fine. The reason I want to use WinPython is to be able to interface it with EyeLink)

  Thanks,

  Martijn

  Hi Martijn,

  Your screenshot has been scaled down and now the error message is too small to make out. Would you mind posting the full error message from the debug window?

  Cheers,

  Sorry forgot to actually post it. Here it is:

  Unexpected error
  
  exception message:
  exception type: WindowsError
  
  Traceback:
  File "C:\WinPython-OpenSesame-2.8.1\OpenSesame\opensesame-2.8.1\libopensesame\exceptions.py", line 74, in __init__
  info[u'line'] = traceback.extract_tb(sys.exc_info()[2])[-1][1]
  IndexError: list index out of range

  Any ideas how to check what is wrong?

  Hi Martijn,

  I'm not sure what's going here. It looks like OpenSesame fails to determine which line triggered the exception. And this error in parsing the error obscures the actual error, if you see what I mean. But I don't really understand why this would happen, and I've never seen it before.

  Is this problem specific for this machine and the WinPython distribution of OpenSesame? For example, if you run the latest 'official' OpenSesame release, do you see the same problem?

  And is there any more output in the debug window?

  Cheers,
  Sebastiaan

  I’m having a similar problem…

  I created an experiment that runs perfectly on a MacBook Pro (OS X; OpenSesame 0.27.4). However, when I try to open the experiment file on my testing machine - a PC (running OpenSesame 2.8.2) - it gives an error message that reads: Unexpected error: exception message. Exception type: WindowsError

  The full error message from the debug window is as follows:

  Unexpected error

  exception message:
  exception type: WindowsError

  Traceback:
  File "dist\libopensesame\exceptions.py", line 74, in init
  IndexError: list index out of range

  See the screenshot below for the error message pop-up window.

  Any help would be much appreciated!

  Many thanks

  Hi Sebastiaan (and cubistular),

  Thanks for your help so far.

  On this particular PC:

  OpenSesame 2.8.0 works fine

  WinPython-OpenSesame-2.8.1 does not work (i.e. the topic of this post)
  Just running a new blank experiment (i.e. only the welcome message) does not work with any back-end (always the same error message)

  opensesameportabble-0.27.1.-1-win32 does also not work
  However, it gives a different error: avbin.dll failed to load. Try importing psychopy.visual as the first library (before anything that uses scipy) and make sure that avbin is installed

  Cheers,

  Martijn

  Hi guys,

  Thanks for letting me know about this problem. I'll try to replicate it and see if I can find the underlying problem. Once I have I'll get back to you.

  opensesameportabble-0.27.1.-1-win32 does also not work However, it gives a different error: avbin.dll failed to load. Try importing psychopy.visual as the first library (before anything that uses scipy) and make sure that avbin is installed

  This looks unrelated. The avbin.dll message is 'normal' in the sense that PsychoPy always complains about that, and it shouldn't cause any issues.

  Cheers,
  Sebastiaan

  Hi,

  I've just come across this problem when trying to do a test run. Similar error message to those reported above...is there a solution to this problem?

  Thanks,

  I've encountered a similar issue before, on a laptop with a very outdated .NET framework. There are two possible solutions to this:

  1) Update the .NET framework.

  2) Do a local installation of Python, including all the dependencies, and use that to run OpenSesame from source.

  Alternatively, do a local installation of Python, and a local installation of PyGame. Then copy the pygame folder from Python's site-packages folder to WinPython's site-packages folder. This could work, but might not fully do it.

  Good luck!
