Error while running the baselines about l2rpn-baselines

[vishrutmishra]

I had the same issue.
What I did to solve this was open 'DoubleDuelingDQN.py' (Since I am in windows it is located in 'C:\Python38\Lib\site-packages\l2rpn_baselines\DoubleDuelingDQN')
Go to line number 101 (in my case it was 131, don't know why it's different for us)
change the line to r_instance = env._reward_helper.template_reward (Add a _ in front of reward_helper)

I went through the code on GitHub and there it was fixed, using try-catch which is a better way to do it. So I don't know why when I installed l2rpn_baselines using pip like today, it still gave the error. (maybe pip install is using an older version ?)

If u want to use the try-catch version:
replace the line with

try:
    # change of name in grid2op >= 1.2.3
    r_instance = env._reward_helper.template_reward
except AttributeError as nm_exc_:
    r_instance = env.reward_helper.template_reward

Hello, installing from source solves this issue completely :-)

I will try to add a fix to the version available in pip as soon as possible

Sorry for the inconvenience,

Benjamin
