VISUAL SEARCH error

RobertaIannace

Hi to everyone! I'm starting to use open sesame and I followed the two tutorials. I have a problem with the second experiment because he give me some error that I don't know how to solve. The errors that appears are those:

Inline script, line 140, in <module>

 Inline script, line 137, in draw_canvas

 Inline script, line 107, in draw_distractor

Exception: Invalid condition: conjuction

I'm trying a lot of things but I can't solve it. I add my file, if anyone can help me- Thank you so much

I noted that if I eliminate this part of the script  (106-107)

else:

raise Exception('Invalid condition: %s' % var.condition)

the experiment works and the errors disappear, but the target or distractors doesn't appear always in each trial. Thanks to everyone that will help me.

Hi @RobertaIannace ,

The error comes, as you noticed yourself, from the draw_distractor() function. This function does something different depending on whether the value condition has the value 'conjunction', 'feature_shape', or 'feature_color'. For any other value, you get the 'Invalid condition' error. (An Exception is the Python term for an error.)

So with that in mind, look critically at your block_loop to see what values you are actually assigning to condition !
