I had an experiment with eye tracker (EyeLink, using PyGaze) which was run OK in PsychoPy 1.82.01.
I now migrated to version 1.84.2 and I encounter the following problems:
- In the experiment, a movie is shown. I can hear the movie but I get a black screen.
- I use a conditions xlsx file in a loop. I did not change anything in the file but at the end of the first iteration I get an error:
File "D:\Rotem\pygaze-cocktail-pilot\CocktailPartyWithQuestionsWorkingAndBreakAddRandom.py", line 400, in <module> trialList=data.importConditions(questions_file), File "C:\Program Files (x86)\PsychoPy2\lib\site-packages\psychopy-1.84.2-py2.7.egg\psychopy\data.py", line 2689, in importConditions _assertValidVarNames(fieldNames, fileName) File "C:\Program Files (x86)\PsychoPy2\lib\site-packages\psychopy-1.84.2-py2.7.egg\psychopy\data.py", line 2601, in _assertValidVarNames raise ImportError(msg % fileName) ImportError: Conditions file questions/04.xlsx: Missing parameter name(s); empty cell(s) in the first row?
Of course the first line is not empty.
What could cause this and how do I fix it ?
Thanks in advance!
