Is it possible to modify the actor's init value?

Ray Core

I wonder if it is possible to change the init value of Environment class declared as actor in MainEnvironment.py in main.py.
What I want is to modify the code in main.py to change self.num_steps in Trainer.py.

#Trainer.py
class TrainerParams:
    def __init__(self):
        self.num_steps = 1e5

class Trainer:
    def __init__(self, params: TrainerParams):
        self.params = params

#MainEnvironment.py
from Environment import BaseEnvironment, BaseEnvironmentParams
from Trainer import TrainerParams, Trainer

class EnvironmentParams(BaseEnvironmentParams):
    def __init__(self):
        super().__init__()
        self.trainer_params = TrainerParams()

@ray.remote
class Environment(BaseEnvironment):
    def __init__(self, params: EnvironmentParams):
        super().__init__(params)
        self.trainer = Trainer(params.trainer_params)

If I can not consider ray, the code can be written as below.

#main.py
from MainEnvironment import Environment

env = Environment(params)
env.trainer.params.num_steps *= 0.4

But I have to consider ray.

#main.py
import ray
from MainEnvironment import Environment

ray.init()
env = [Environment.remote(params) for i in range(2)]
ray.actor.exit_actor()
for i in range(2):
    env[i].trainer.params.num_steps *= 0.4

I guess I need to access the init value after terminating ray.init().
But it doesn’t work. I also suspect that accessing the actor without .remote() is one cause of the error, but I can’t find a solution.

I solve my problem thanks to " Passing Around Actor Handles" in the ray official website.
