TypeError: tuple indices must be integers or slices, not tuple

Hello.

Thanks for your codes, but I got some errors.

I’m using your env.py, so I renamed the env folder and changed from env import envs to import env as envs. Is it correct?

Since I only have CPU, I change self.sess = tf.Session(config=tf.ConfigProto(log_device_placement=True)) to self.sess = tf.Session() But maybe this is not related to the errors.

When I ran the codes, I get such errors:

Traceback (most recent call last):
  File "/Applications/PyCharm.app/Contents/helpers/pydev/pydev_run_in_console.py", line 53, in run_file
    pydev_imports.execfile(file, globals, locals)  # execute the script
  File "/Applications/PyCharm.app/Contents/helpers/pydev/_pydev_imps/_pydev_execfile.py", line 18, in execfile
    exec(compile(contents+"\n", file, 'exec'), glob, loc)
  File “xx/scalable_maddpg/main.py", line 44, in <module>
    action = maddpg.noise_action(current_state)
  File “xx/scalable_maddpg/maddpg.py", line 158, in noise_action
    action = self.action(state)
  File “xx/scalable_maddpg/maddpg.py", line 138, in action
    action[ii,:] = self.agents[ii].action(state[ii,:])
TypeError: tuple indices must be integers or slices, not tuple

I tried to solve it by changing action[ii,:] = self.agents[ii].action(state[ii,:]) to action[ii,:] = self.agents[ii].action(state[ii]), but it lead to other errors.

Do you have some idea of the errors? Thank you.

Since you are using the env.py as the environment, the prey policy should be implemented outside the environment by yourself. This is a little different from the modified gym environment which we implement the prey policy inside the environment. You can refer this repository to see how to use env.py correctly.

I am not sure whether this is caused by the environment.

Hello! I got the same error when running the main.py main_add_agents.py, slow_replay.py files, as shown below: Traceback (most recent call last):    File "main.py", line 16, in      Env = envs.Environ (num_agents, max_edge)    File "/home/dcy/MADDPG/scalable_maddpg-master/env/envs.py", line 23, in init      = self.create_env (num_agents,)    File "/home/dcy/MADDPG/scalable_maddpg-master/env/envs.py", line 37, in create_env      shared_viewer = False)    File "env / multiagent / environment.py", line 71, in init      self.observation_space.append (spaces.Box (low = -np.inf, high = + np.inf, shape = (obs_dim),))    File "/home/dcy/anaconda3/lib/python3.6/site-packages/gym/spaces/box.py", line 34, in init      gym.Space . init (self, shape, dtype)    File "/home/dcy/anaconda3/lib/python3.6/site-packages/gym/core.py", line 202, in init      self.shape = None if shape is None else tuple (shape) TypeError: 'int' object is not iterable Excuse me, what is the reason for this?

Would you please delete the env folder and try our env.py implementation. You can refer this repository .
