## Installation
For maximum training performance a preliminary installation of Pytorch 1.9+ with CUDA 11.1+ is highly recommended:
```conda install pytorch torchvision cudatoolkit=11.3 -c pytorch -c nvidia``` or:
```pip install torch==1.11.0+cu113 torchvision==0.12.0+cu113 -f https://download.pytorch.org/whl/cu113/torch_stable.html```
Then:
```pip install rl-games```
To run CPU-based environments either Ray or envpool are required ```pip install envpool``` or ```pip install ray```
To run Mujoco, Atari games or Box2d based environments training they need to be additionally installed with ```pip install gym[mujoco]```, ```pip install gym[atari]``` or ```pip install gym[box2d]``` respectively.
To run Atari also ```pip install opencv-python``` is required. In addition installation of envpool for maximum simulation and training perfromance of Mujoco and Atari environments is highly recommended: ```pip install envpool```

## Custom network example:
[simple test network](rl_games/envs/test_network.py)
This network takes dictionary observation.
To register it you can add code in your __init__.py
```
from rl_games.envs.test_network import TestNetBuilder
from rl_games.algos_torch import model_builder
model_builder.register_network('testnet', TestNetBuilder)
```
[simple test environment](rl_games/envs/test/rnn_env.py)
[example environment](rl_games/envs/test/example_env.py)

## Release Notes
1.6.1
* Fixed Central Value RNN bug which occurs if you train ma multi agent environment.
* Added Deepmind Control PPO benchmark.
* Added a few more experimental ways to train value prediction (OneHot, TwoHot encoding and crossentropy loss instead of L2).
* New methods didn't. It is impossible to turn it on from the yaml files. Once we find an env which trains better it will be added to the config.
* Added shaped reward graph to the tensorboard.
* Fixed bug with SAC not saving weights with save_frequency.
* Added multi-node training support for GPU-accelerated training environments like Isaac Gym. No changes in training scripts are required. Thanks to @ankurhanda and @ArthurAllshire for assistance in implementation.
* Added evaluation feature for inferencing during training. Checkpoints from training process can be automatically picked up and updated in the inferencing process when enabled.
* Added get/set API for runtime update of rl training parameters. Thanks to @ArthurAllshire for the initial version of fast PBT code.
* Fixed SAC not loading weights properly.
* Removed Ray dependency for use cases it's not required.
* Added warning for using deprecated 'seq_len' instead of 'seq_length' in configs with RNN networks.
1.6.0
* Added ONNX export colab example for discrete and continious action spaces. For continuous case LSTM policy example is provided as well.
* Improved RNNs training in continuous space, added option `zero_rnn_on_done`.
* Added NVIDIA CuLE support: https://github.com/NVlabs/cule
* Added player config everride. Vecenv is used for inference.
* Fixed multi-gpu training with central value.
* Fixed max_frames termination condition, and it's interaction with the linear learning rate: https://github.com/Denys88/rl_games/issues/212
* Fixed "deterministic" misspelling issue.
* Fixed Mujoco and Brax SAC configs.
* Fixed multiagent envs statistics reporting. Fixed Starcraft2 SMAC environments.
1.5.2
* Added observation normalization to the SAC.
* Returned back adaptive KL legacy mode.
1.5.1
* Fixed build package issue.
1.5.0
* Added wandb support.
* Added poetry support.
* Fixed various bugs.
* Fixed cnn input was not divided by 255 in case of the dictionary obs.
* Added more envpool mujoco and atari training examples. Some of the results: 15 min Mujoco humanoid training, 2 min atari pong.
* Added Brax and Mujoco colab training examples.
* Added 'seed' command line parameter. Will override seed in config in case it's > 0.
* Deprecated `horovod` in favor of `torch.distributed` ([#171](https://github.com/Denys88/rl_games/pull/171)).
1.4.0
* Added discord channel https://discord.gg/hnYRq7DsQh :)
* Added envpool support with a few atari examples. Works 3-4x time faster than ray.
* Added mujoco results. Much better than openai spinning up ppo results.
* Added tcnn(https://github.com/NVlabs/tiny-cuda-nn) support. Reduces 5-10% of training time in the IsaacGym envs.
* Various fixes and improvements.
1.3.2
* Added 'sigma' command line parameter. Will override sigma for continuous space in case if fixed_sigma is True.
1.3.1
* Fixed SAC not working
1.3.0
* Simplified rnn implementation. Works a little bit slower but much more stable.
* Now central value can be non-rnn if policy is rnn.
* Removed load_checkpoint from the yaml file. now --checkpoint works for both train and play.
1.2.0
* Added Swish (SILU) and GELU activations, it can improve Isaac Gym results for some of the envs.
* Removed tensorflow and made initial cleanup of the old/unused code.
* Simplified runner.
* Now networks are created in the algos with load_network method.
1.1.4
* Fixed crash in a play (test) mode in player, when simulation and rl_devices are not the same.
* Fixed variuos multi gpu errors.
1.1.3
* Fixed crash when running single Isaac Gym environment in a play (test) mode.
* Added config parameter ```clip_actions``` for switching off internal action clipping and rescaling
1.1.0
* Added to pypi: ```pip install rl-games```
* Added reporting env (sim) step fps, without policy inference. Improved naming.
* Renames in yaml config for better readability: steps_num to horizon_length amd lr_threshold to kl_threshold
## Troubleshouting
* Some of the supported envs are not installed with setup.py, you need to manually install them
* Starting from rl-games 1.1.0 old yaml configs won't be compatible with the new version:
* ```steps_num``` should be changed to ```horizon_length``` amd ```lr_threshold``` to ```kl_threshold```
## Known issues
* Running a single environment with Isaac Gym can cause crash, if it happens switch to at least 2 environments simulated in parallel
