Re: [starpu-devel] Subject: Feedback on ImportError when importing "starpu" in Python

[Nathalie Furmento <nathalie.furmento@labri.fr>]

Can you check that the starpu_save_history_based_model symbol really is in 
the libstarpu that is actually getting loaded ?

and please also tell us which branch / commit version of StarPU you are using 
?

Cheers,

Nathalie
