wrapper problem under simple_speaker_listener environment

[CaptainYin]

when using simple_speaker_listener environment, the observation dimension of speaker and lisener is not the same, so there is a problem when wrapper the env by env_wrappers.py

execute this shell
`#!/bin/sh
env="MPE"
scenario="simple_speaker_listener"
#"simple_speaker_listener" "simple_spread"
num_landmarks=3
num_agents=2
algo="rmaddpg"
exp="debug"
seed_max=1

echo "env is ${env}, scenario is ${scenario}, algo is ${algo}, exp is ${exp}, max seed is ${seed_max}"

for seed in $(seq ${seed_max}); do
echo "seed is ${seed}:"
CUDA_VISIBLE_DEVICES=0 python3 train/train_mpe.py --env_name ${env} --n_rollout_threads 1 --algorithm_name ${algo} --experiment_name ${exp} --scenario_name ${scenario} --num_agents ${num_agents} --num_landmarks ${num_landmarks} --seed ${seed} --episode_length 25 --actor_train_interval_step 1 --tau 0.005 --lr 7e-4 --num_env_steps 10000000 --use_reward_normalization --share_policy
echo "training is done!"
done
`
output
