Replicate code for Pretrained Policy

[Maya199x]

Hey there I am trying to replicate the code and I've got a question! This is my first time opening an issue - if I forget something vital to include please tell me.

Installing the requirements with pip install -r requirements.txt and executing python policy/reinforce.py --exp_name MultiBandit and also python policy/reinforce.py --exp_name GridWorld has worked.

The problem I have encountered is in trying to execute 'python policy/reinforce.py --exp_name CartPole'.

I get this error log:

❯ python policy/reinforce.py --exp_name CartPole
/Users/maya199x/miniforge3/envs/testCode/lib/python3.10/site-packages/gym/envs/registration.py:555: UserWarning: WARN: The environment CartPole-v0 is out of date. You should consider upgrading to version `v1`.
  logger.warn(

    return getattr(self.env, name)
AttributeError: 'CartPoleEnv' object has no attribute 'seed'

Is there some issue with my installation? Or is it something else entirely? Any help would be much appreciated!

I am running the code on a macbook m1 2020, in a conda virtual environment with python version 3.10.6.
