traj_list = [map(list, zip(*traj_list))] should be changed into traj_list = list(zip(*traj_list)) and cur_items = [map(list, zip(*traj_list))] should be changed into cur_items = list(zip(*traj_list))

We have fixed these bugs for the main algorithms (DQN, DoubleDQN, DualingDQN, D3QN, DDPG, TD3, SAC and PPO), the algorithm related to Hterm has not been updated (DDPG_H, PPO_H), thank you for the reminder, I will take the time to change these codes.

We had update these code for the main algorithms just like:
