# Optional Stable-Baselines3 cross-check dependencies.
#
# These are ONLY needed to run deepqlearning/sb3/cross_check.py, which trains an external SB3
# DQN/PPO agent on the same environment as an independent sanity bound. Nothing in the main
# trainer, the environment, or the test suite imports Stable-Baselines3 — install this file only
# if you want to run the cross-check.
#
#   pip install -r requirements-rl.txt -r requirements-rl-sb3.txt

stable-baselines3>=2.9.0
