Yade

Software requirements for a successfull O.save/O.load

Asked by Jérôme Duriez

Hi,

I know we need to use the same YADE version compiled or built with the same features for being able to O.save() / O.load() (with no error, and leaving here "not defined" Python considerations outside of the question) [*] .

Should we expect further requirements, e.g. in terms of having the same external package versions between the respective times (or used machines) of O.save and O.load ?

If yes, would it be possible to pinpoint at specific packages that should remain identical ? (libboost-all-dev ? something else ?)

Edit: I'm currently facing a "RuntimeError: unregistered class" at O.load, with boost 1.71.0. No idea what boost was at O.save

Thanks

Hi,
since the save/load is done using the boost library [1,2], I think the same version of boost might be essential.
Cheers
Jan

Thanks for feedback Jan. I could not track my "RuntimeError: unregistered class" load error in YADE source code so I'm still a bit unsure of the exact source, but that confirms my boost feelings.

Note https://gitlab.com/yade-dev/trunk/-/merge_requests/709 by the way.
