The large environment is smaller in size than the small environment

[Mleyliabadi]

After examining both small and large environments (ai4realnet_small) and (ai4realnet_large), they occupies 11 and 4 Mb on disk respectively. Is it normal ?

Also I could not make the large environment using the following code and using grid2op version '1.9.0' :

import grid2op
env_large = grid2op.make(dataset="ai4realnet_large")

I have the following error

cannot import name 'AlertReward' from 'grid2op.Reward' (/home/milad/miniconda3/envs/l2rpn_baselines_old/lib/python3.7/site-packages/grid2op/Reward/__init__.py)

@Mleyliabadi could you try with the latest version of grid2op ? AlertReward has been introduced quite recently

@brunolemetayer Thank you for this answer. I confirm that using the last version of Grid2op solved my error. However, the number of chronics and timesteps for this large environment is less than the small one. There are only two chronics with 575 time stamps.

 10M	./ai4realnet_small
