## Introduction to DI-engine
[Documentation](https://di-engine-docs.readthedocs.io/en/latest/) | [中文文档](https://di-engine-docs.readthedocs.io/zh_CN/latest/) | [Tutorials](https://di-engine-docs.readthedocs.io/en/latest/01_quickstart/index.html) | [Feature](#feature) | [Task & Middleware](https://di-engine-docs.readthedocs.io/en/latest/03_system/index.html) | [TreeTensor](#general-data-container-treetensor) | [Roadmap](https://github.com/opendilab/DI-engine/issues/548)
**DI-engine** is a generalized decision intelligence engine for PyTorch and JAX.
It provides **python-first** and **asynchronous-native** task and middleware abstractions, and modularly integrates several of the most important decision-making concepts: Env, Policy and Model. Based on the above mechanisms, DI-engine supports **various [deep reinforcement learning](https://di-engine-docs.readthedocs.io/en/latest/10_concepts/index.html) algorithms** with superior performance, high efficiency, well-organized [documentation](https://di-engine-docs.readthedocs.io/en/latest/) and [unittest](https://github.com/opendilab/DI-engine/actions):
- Most basic DRL algorithms: such as DQN, Rainbow, PPO, TD3, SAC, R2D2, IMPALA
- Multi-agent RL algorithms: such as QMIX, WQMIX, MAPPO, HAPPO, ACE
- Imitation learning algorithms (BC/IRL/GAIL): such as GAIL, SQIL, Guided Cost Learning, Implicit BC
- Offline RL algorithms: BCQ, CQL, TD3BC, Decision Transformer, EDAC, Diffuser, Decision Diffuser, SO2
- Model-based RL algorithms: SVG, STEVE, MBPO, DDPPO, DreamerV3, MuZero
- Exploration algorithms: HER, RND, ICM, NGU
- LLM + RL Algorithms: PPO-max, DPO, MPDPO
- Other algorithms: such as PER, PLR, PCGrad
**DI-engine** aims to **standardize different Decision Intelligence environments and applications**, supporting both academic research and prototype applications. Various training pipelines and customized decision AI applications are also supported:

### General Data Container: TreeTensor
DI-engine utilizes [TreeTensor](https://github.com/opendilab/DI-treetensor) as the basic data container in various components, which is ease of use and consistent across different code modules such as environment definition, data processing and DRL optimization. Here are some concrete code examples:
- TreeTensor can easily extend all the operations of `torch.Tensor` to nested data:
(Click for Details)
```python
import treetensor.torch as ttorch
# create random tensor
data = ttorch.randn({'a': (3, 2), 'b': {'c': (3, )}})
# clone+detach tensor
data_clone = data.clone().detach()
# access tree structure like attribute
a = data.a
c = data.b.c
# stack/cat/split
stacked_data = ttorch.stack([data, data_clone], 0)
cat_data = ttorch.cat([data, data_clone], 0)
data, data_clone = ttorch.split(stacked_data, 1)
# reshape
data = data.unsqueeze(-1)
data = data.squeeze(-1)
flatten_data = data.view(-1)
# indexing
data_0 = data[0]
data_1to2 = data[1:2]
# execute math calculations
data = data.sin()
data.b.c.cos_().clamp_(-1, 1)
data += data ** 2
# backward
data.requires_grad_(True)
loss = data.arctan().mean()
loss.backward()
# print shape
print(data.shape)
# result
#
# ├── 'a' --> torch.Size([1, 3, 2])
# └── 'b' -->
# └── 'c' --> torch.Size([1, 3])
```
- TreeTensor can make it simple yet effective to implement classic deep reinforcement learning pipeline
(Click for Details)
```diff
import torch
import treetensor.torch as ttorch
B = 4
def get_item():
return {
'obs': {
'scalar': torch.randn(12),
'image': torch.randn(3, 32, 32),
},
'action': torch.randint(0, 10, size=(1,)),
'reward': torch.rand(1),
'done': False,
}
data = [get_item() for _ in range(B)]
# execute `stack` op
- def stack(data, dim):
- elem = data[0]
- if isinstance(elem, torch.Tensor):
- return torch.stack(data, dim)
- elif isinstance(elem, dict):
- return {k: stack([item[k] for item in data], dim) for k in elem.keys()}
- elif isinstance(elem, bool):
- return torch.BoolTensor(data)
- else:
- raise TypeError("not support elem type: {}".format(type(elem)))
- stacked_data = stack(data, dim=0)
+ data = [ttorch.tensor(d) for d in data]
+ stacked_data = ttorch.stack(data, dim=0)
# validate
- assert stacked_data['obs']['image'].shape == (B, 3, 32, 32)
- assert stacked_data['action'].shape == (B, 1)
- assert stacked_data['reward'].shape == (B, 1)
- assert stacked_data['done'].shape == (B,)
- assert stacked_data['done'].dtype == torch.bool
+ assert stacked_data.obs.image.shape == (B, 3, 32, 32)
+ assert stacked_data.action.shape == (B, 1)
+ assert stacked_data.reward.shape == (B, 1)
+ assert stacked_data.done.shape == (B,)
+ assert stacked_data.done.dtype == torch.bool
