Optimize => Process stoped

[pliciwebstephane]

Hello,

I run optimize on my strategy with many differents combinations.
And when i run my script, i see the french message "processus arrêté" (in english "Process stopped").

Anyone can help me ?

my debug, let me think the problem is with this code :

param_combos = [dict(params)  # back to dict so it pickles
                            for params in (AttrDict(params)
                                           for params in product(*(zip(repeat(k), _tuple(v))
                                                                   for k, v in kwargs.items())))
                            if constraint(params)  # type: ignore
                            and rand() <= grid_frac]
