result.x = None
if simulation fails at the startpoint.result.x
is used to compute hierarchical inner parameters after optimization. Whenresult.x = None
, an AMICI simulation to compute inner parameters is still run, unexpectedly... I didn't look deeper there, but this PR stops the computation of inner parameters if simulation fails at the startpoint (defined byresult.x = None
).This PR means users do not see
NaN in p
AMICI simulation errors due toresult.x = None
. This can be confusing for users, who then try (and fail) to reproduce those errors withobjective(result.x0)
.
