Hello,

高家隆, le lun. 06 nov. 2023 14:51:20 +0800, a ecrit:

This looks like you are mixing different versions of StarPU?

You can make sure which libstarpu is actually used by running

ldd
/usr/local/lib/python3.10/site-packages/starpu/starpupy.cpython-310-x86_64-linux-gnu.so

and check that the starpu_save_history_based_model symbol really is in
the libstarpu that is actually getting loaded, or fix your
LD_LIBRARY_PATH in order to load the proper version.

Samuel
