Hi! I am trying to run an experiment that was built in the new version of Psychopy (2021.1.2) in an older version (v3.2.4). Long story short - the old version is what we have installed on the scanning computer and we can’t update it without compromising other people’s experiments.
The new task (fully built in the builder) won’t run on the older version, or even compile to script. We get this error when we try to compile: “TypeError: Can’t represent a Param of type color” as well as several warnings, including “67088.6736 WARNING Parameter ‘contrast’ is not known to this version of PsychoPy but has come from your experiment file (saved by a future version of PsychoPy?). This experiment may not run correctly in the current version.”
We have tried copying over individual routines, including just simple text objects, but we get the same error.
Is there any way to get it to run on version 3.2.4 without rebuilding the entire experiment?
Advice is much appreciated. Thanks.
