Problems with startpoint method

[shoepfl]

I have a problem with optimize.minimize:

optimizer = optimize.ScipyDifferentialEvolutionOptimizer(options = {'strategy':'best1bin', 'maxiter':8000 ,'mutation':(0.5, 1), 'recombination':0.9, 'popsize':100, 'init':'latinhypercube', 'polish':True, 'workers' : 8 })
n_starts = 1
result = optimize.minimize(petab_problem, optimizer=optimizer, n_starts=n_starts)

Results in : AttributeError: 'Problem' object has no attribute 'x_guesses'

I thought it may be that i do not need startpoints as they are created in scypy but also startpoint_method = False in optimize.minimize rises an error: AttributeError: 'Problem' object has no attribute 'dim'

This problem probably occoured through updating my dependencies as this code worked before.
Can you tell me what changed and how to fix this?

Thanks! and Best,
Sebastian

I guess that petab_problem should be switched with a pypesto.Problem object in your optimize.minimize call.

Ah thank you very much for the fast answer @dilpath !

Of course that was my mistake - sometimes i get confused with the petab and pypesto problems.
