TypeError: coercing to Unicode: need string or buffer, int found

[semeon...@gmail.com]

Hello all - 

I'm having a bit of trouble passing an experiment through WinPython. I've include the code preceding the error, as well as the error message that pops up. The experiment works on the standalone version of psychopy as well as running it through an installed version of python 2.7.10 on my pc. Unfortunately the experiment needs to be run through WinPython.

# set up handler to look after randomisation of conditions etc

Introduction_Loop = data.TrialHandler(nReps=1, method='sequential', 

    extraInfo=expInfo, originPath=-1,

    trialList=data.importConditions('procedure\\Introduction.csv'),

    seed=None, name='Introduction_Loop')

Python 2.7.10 (default, May 23 2015, 09:40:32) [MSC v.1500 32 bit (Intel)] on win32

Type "copyright", "credits" or "license()" for more information.

Hello Semeon?,

The error message points specifically to you using a value of -1 for the originPath parameter, when this needs to be a string of characters (representing a file path on your computer). It is optional for most purposes anyway, so you can likely just omit that parameter.

This error wouldn't be specific to a given platform or installation of PsychoPy…

Regards,

Michael
