Hi Alex, Yeah, this one is going to be a little bit annoying to fix. Here's what's going on: in between 3.1.1 and 3.2.3, fraction fields got moved over to the new coercion model. This is good, but as it happens, the switch was done in such a way that it caused the pre-existing pickles to not load correctly (which is exactly what you're seeing). There's probably a clean and classy way to fix this, and I'll be happy to look at it carefully in a few weeks if no one beats me to it (I'm busy trying to finish up my thesis). This is now trac #5419. In the interim, you probably want to hack something together so that you can load your pickles. I managed to make sage 3.2.3 load the pickles, but it's a pretty ugly hack, and you'll still need to re-save the objects as newer pickles (which actually has one or two more wrinkles), so that you don't have to deal with this in the short term. How many of these files are there? If it's just a few, e-mail them to me off-list, and I'll just re-pickle them in a newer format and send them back to you. If there are more than that, I'll carefully explain how you can fix them yourself. :) -cc --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
