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 algorithms with superior performance, high efficiency, well-organized documentation and unittest:
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:
Traditional academic environments
Tutorial courses
Real world decision AI applications
Research paper
Docs and Tutorials
On the low-level end, DI-engine comes with a set of highly re-usable modules, including RL optimization functions, PyTorch utilities and auxiliary tools.
BTW, DI-engine also has some special system optimization and design for efficient and robust large-scale RL training:
Have fun with exploration and exploitation.
You can simply install DI-engine from PyPI with the following command:
pip install DI-engine
If you use Anaconda or Miniconda, you can install DI-engine from conda-forge through the following command:
conda install -c opendilab di-engine
For more information about installation, you can refer to installation.
And our dockerhub repo can be found here,we prepare base image
and env image
with common RL environments.

P.S. some enviroments in Atari, such as MontezumaRevenge, are also the sparse reward type.
DI-engine utilizes 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:
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
# <Size 0x7fbd3346ddc0>
# ├── 'a' --> torch.Size([1, 3, 2])
# └── 'b' --> <Size 0x7fbd3346dd00>
# └── 'c' --> torch.Size([1, 3])
TreeTensor can make it simple yet effective to implement classic deep reinforcement learning pipeline
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)
