How to use the arbor.partition_hint function in arbor

context = arbor.context(threads=4, gpu_id=None)
print(context)

meters = arbor.meter_manager()
meters.start(context)

recipe = ring_recipe(10)
print(f'{recipe}')

meters.checkpoint('recipe-create', context)

decomp = arbor.partition_load_balance(recipe, context)
print(f'{decomp}')

hint = arbor.partition_hint()
hint.prefer_gpu = True
hint.gpu_group_size = 1000
print(f'{hint}')

hints = dict([(arbor.cell_kind.cable, hint)])
decomp = arbor.partition_load_balance(recipe, context, hints)
print(f'{decomp}')

meters.checkpoint('load-balance', context)

sim = arbor.simulation(recipe, decomp, context)

meters.checkpoint('simulation-init', context)

spike_recorder = arbor.attach_spike_recorder(sim)
