Fwd: [psychopy-users] Re: Error loading an experiment

Jon,

Do you have a timeline for the next bugfix release? This 'term' issue seems worth sorting out.

The commit history is not straightforward for the flow.py file, but its all there in older versions of builder.py. There are two lines of code in the entire codebase that contain 'term', and they are both in the flow part of the builder, authored by you on Nov 27, 2009. So it seems like tried and true code. 

So my guess is that the loop terminator in the .psyexp file is not being saved correctly for some reason (but only in some infrequent circumstances).

I can easily delay the start of style refactoring to prioritize this fix, if you like.

I'm having the same problem: using v 1.83.03 on a Mac running OS X. I saved and closed the builder experiment, opened a different one, then reopened the original one and got the following error message:

Any help with sorting this one out would be much appreciated.

Many thanks,

Anneke

Hello!

I am using psychopy v1.82.01 on macbook with OSX 10.10.4. I tried to load an experiment I built in the builder mode today, but failed to do so and get the following message:

I was still able to open that file couple days ago, and I am able to open other experiments now. Could you suggest what I should do to get this experiment running again? Thank you so much!

Best regards,

Lisa

Hmmm, probably something to do with the 'nan' failure earlier, I missed that on my first read.

OK, sure. I don't know off the top of my head why this would be an issue. I think we need to get hold of one of the files. To see why it isn't working. Weird that two people have slightly different but related errors together.

And the other one had an issue with missing ISI (maybe a static component that had been removed but had something pointing to it)

I think the ITI one makes sense, and is different.

I'm wondering if the new-ish xml handling is having an intermittent issue somehow (was it a new xml package or something?)
