SB3 v1.6.1: Bug fix release

SB3 Contrib: https://github.com/Stable-Baselines-Team/stable-baselines3-contrib

Breaking Changes:

• Switched minimum tensorboard version to 2.9.1

New Features:

• Support logging hyperparameters to tensorboard (@​timothe-chaumont)
• Added checkpoints for replay buffer and VecNormalize statistics (@​anand-bala)
• Added option for Monitor to append to existing file instead of overriding (@​sidney-tio)
• The env checker now raises an error when using dict observation spaces and observation keys don't match observation space keys

SB3-Contrib

• Fixed the issue of wrongly passing policy arguments when using CnnLstmPolicy or MultiInputLstmPolicy with RecurrentPPO (@​mlodel)

Bug Fixes:

• Fixed issue where PPO gives NaN if rollout buffer provides a batch of size 1 (@​hughperkins)
• Fixed the issue that predict does not always return action as np.ndarray (@​qgallouedec)
• Fixed division by zero error when computing FPS when a small number of time has elapsed in operating systems with low-precision timers.
• Added multidimensional action space support (@​qgallouedec)
• Fixed missing verbose parameter passing in the EvalCallback constructor (@​burakdmb)
• Fixed the issue that when updating the target network in DQN, SAC, TD3, the running_mean and running_var properties of batch norm layers are not updated (@​honglu2875)
• Fixed incorrect type annotation of the replay_buffer_class argument in common.OffPolicyAlgorithm initializer, where an instance instead of a class was required (@​Rocamonde)
• Fixed loading saved model with different number of envrionments
• Removed forward() abstract method declaration from common.policies.BaseModel (already defined in torch.nn.Module) to fix type errors in subclasses (@​Rocamonde)
• Fixed the return type of .load() and .learn() methods in BaseAlgorithm so that they now use TypeVar (@​Rocamonde)
• Fixed an issue where keys with different tags but the same key raised an error in common.logger.HumanOutputFormat (@​Rocamonde and @​AdamGleave)

Others:

• Fixed DictReplayBuffer.next_observations typing (@​qgallouedec)
• Added support for device="auto" in buffers and made it default (@​qgallouedec)
• Updated ResultsWriter` (used internally by Monitorwrapper) to automatically create missing directories whenfilename`` is a path (@​dominicgkerr)

Documentation:

• Added an example of callback that logs hyperparameters to tensorboard. (@​timothe-chaumont)
• Fixed typo in docstring "nature" -> "Nature" (@​Melanol)
• Added info on split tensorboard logs into (@​Melanol)
• Fixed typo in ppo doc (@​francescoluciano)
• Fixed typo in install doc(@​jlp-ue)
• Clarified and standardized verbosity documentation
• Added link to a GitHub issue in the custom policy documentation (@​AlexPasqua)
• Fixed typos (@​Akhilez)
