Hello,
I am just learning how to code in Python. I downloaded a version of an RDK task with a code component for a staircase method from Gitlab (created by @Becca) for remote research.
I have encountered the following error:
line 1125, in
trials.addData(‘thisStair’, thisStair[‘name’])
File “/Applications/PsychoPy 4.app/Contents/Resources/lib/python3.8/psychopy/data/trial.py”, line 731, in addData
self.data.add(thisType, value, position=None)
File “/Applications/PsychoPy 4.app/Contents/Resources/lib/python3.8/psychopy/data/base.py”, line 532, in add
repN = sum(self[‘ran’][self.trials.thisIndex])
TypeError: ‘numpy.float32’ object is not iterable
################ Experiment ended with exit code 1 [pid:28613] #################
324.1558 DEBUG DlgLoop: could not determine if a condition filename was edited
The trial routine begins with a text component and a dot video. Once I make a response (press either the left or the right key), the task crashes. No more trials run after that.
I think the error in the code can be found in the “end routine” section of my code component.

remove it from the list of stairs

stairs.pop()
print(‘nReversals reached, ending this staircase’)
elif thisStair[‘trialCount’] == thisStair[‘nTrials’]:
completedStairs.append(thisStair)
stairs.pop()
print(‘nTrials reached, ending this staircase’)
if len(stairs)==0:
print(‘stairs completed, ending now’)
continueRoutine = False
trials.finished=True
I am using v2022.1.1 of PsychoPy, macOS Catalina (v10.15.7)
Thank you in advance for your help!
