same issue with torch agent

[RAFAY-AAMIR-GULL]

Hey Hi , I'm getting the same error:

state = T.tensor([observation], dtype=T.float).to(self.actor.device) Traceback (most recent call last): File "/home/rafay/RL/ReinforcementLearning/PolicyGradient/PPO/torch/main.py", line 33, in action, prob, val = agent.choose_action(observation) File "/home/rafay/RL/ReinforcementLearning/PolicyGradient/PPO/torch/ppo_torch.py", line 142, in choose_action state = T.tensor([observation], dtype=T.float).to(self.actor.device) ValueError: expected sequence of length 4 at dim 2 (got 0)

@Zaibali9999 if you have solved the issue, can you please help me out? @philtabor please guide.

Thanks
