Description of the problem:
I created an experiment in the builder in version 2023.1, but then wanted to change the version to 2022.5. I changed the settings, “Use PsychoPy version” to 2022.2.5. I’m now getting a htmlAlert 4051:
Experiment was built in a future version of PsychoPy (2023.1.0rc8), we recommend either updating PsychoPy or changing the "Use Version" setting in Experiment Settings to this version.
I’ve tried a bunch of approaches, including reinstalling different versions of PsychoPy, and changing “Use PsychoPy version” in the builder, and I can’t get rid of this error. I’m getting several problems when I run the program in psychJS (both through pavlovia, and local), and I suspect that this is the root cause of some of these. It seems like the best option at this point is to completely rebuild the experiment with the psychopy version that I want, without using the “Use Version” setting.
Am I missing something here? Is it possible that the “Use PsychoPy version” functionality is not robust in the latest version?
It is a bit more serious for me than that unfortunately!
I’ve coded an experiment in Builder version 2023.2.3, but I decided to run it in 2022.2.5 (using the experiment settings) because of the error described in the post below which hasn’t been resolved:
I built the experiment on my laptop (Windows 10) and have now moved to a separate computer (Windows 7) with an eye tracker to actually run the experiment. However, when I run it (on the actual 2022.2.3 Builder, but in version 2022.2.5 using experiment settings), I get this error message:
ValueError: Unknown version ‘2022.2.5’
Therefore, it seems that I can’t run the experiment on any older versions of PsychoPy on this computer (using the experiment settings). In fact, no other versions even come up as an option in the experiment settings. The only option in experiment settings is 2023.2.3.
To address this, I directly downloaded the 2022.2.5 Builder via the .exe file and uninstalled the 2023.2.3 program. I then tried to run the experiment, but received the error described above. Then, after seeing:
INFO Loaded monitor calibration from [‘2019_10_25 15:41’]
Nothing happens! I press the green play button, but the Experiment Settings box (with version, participant number, etc) never appears.
Any thoughts? Your help would be hugely appreciated!
Unfortunately I’ve just tried running the legacy builder file in the old (2022.2.5) version, but I have exactly the same problem
The “INFO Loaded monitor calibration” message appears, and then nothing happens. However, before that message comes up, I do actually get an error, as shown in the photo below:
