Case

I tried to build a Remote Mujoco env wrapper, and write a class to pass env's data(mainly action_space & observation_space). But I got the following error.

• Dependencies are the same: Linux, parl=1.4

Error:

Code

import gym
import parl
class ActionSpace(object):
    def __init__(self, low, high, shape=None):
        super(ActionSpace, self).__init__()
        self.low = low
        self.high = high
        self.shape = shape

@parl.remote_class
class RemoteEnv(object):
    def __init__(self, env_name=None):
        super(RemoteEnv, self).__init__()
        self.env = gym.make(env_name)
        self.action_space = ActionSpace(self.env.action_space.low,
                                        self.env.action_space.high,
                                        self.env.action_space.shape)

parl.connect('localhost')
env = RemoteEnv(env_name='HalfCheetah-v1')
action_dim = env.action_space.shape[0]
print(action_dim, max_action)

It can work in this way, but seems not to be convenient

import gym
import parl

@parl.remote_class
class RemoteEnv(object):
    def __init__(self, env_name=None):
        super(RemoteEnv, self).__init__()

        class ActionSpace(object):
        def __init__(self, low, high, shape=None):
            super(ActionSpace, self).__init__()
            self.low = low
            self.high = high
            self.shape = shape

        self.env = gym.make(env_name)
        self.action_space = ActionSpace(self.env.action_space.low,
                                        self.env.action_space.high,
                                        self.env.action_space.shape)

parl.connect('localhost:8080')
env = RemoteEnv(env_name='HalfCheetah-v1')
action_dim = env.action_space.shape[0]
print(action_dim)
