Demo programs doesn't work

Hi,

I just finished installing psychopy and was trying to run demo’s.

TimeByFrames.py works fine, but I get an error when I tried to run experimentHandler.py and TrialHandler.py

The following error message is what I got:

runfile('C:/Users/user/Miniconda3/envs/py27/Lib/site-packages/psychopy/demos/coder/experiment control/TrialHandler.py', wdir='C:/Users/user/Miniconda3/envs/py27/Lib/site-packages/psychopy/demos/coder/experiment control')
Traceback (most recent call last):

IndexError: only integers, slices (`:`), ellipsis (`...`), numpy.newaxis (`None`) and integer or boolean arrays are valid indices

It seems to be related to indexing, but I couldn’t figure out how to solve this.

Plz anyone give me some advice.
