ray.tune.run_experiments checkpoints the model at some path like "/ray_results/test/DDPG_VAV-v0_0_2019-04-17_21-43-43ak0121vf/", it is too lengthy, how can I change this checkpoint path
run_experiments({
'test': {
"resources_per_trial": resource,
'run': 'DDPG',
'env': 'Pendulum-v0',
'config': {
"input_evaluation": [],
'exploration_final_eps': 0,
'exploration_fraction': 0},
'checkpoint_at_end': True,
'checkpoint_freq': 500,
'stop': {"training_iteration": 5000}}
})
I hope I can set it like "~/ray_results/test/DDPG_2019-04-17/"
