写给新手的 cann-recipes-embodied-intelligence:昇腾具身智能最佳实践到底是啥?
之前帮兄弟搞机器人项目,他问我:“哥,昇腾上有没有具身智能的最佳实践?我自己在那调 Mujoco,性能惨不忍睹。”
我说有,cann-recipes-embodied-intelligence。
好问题。今天一次说清楚。
cann-recipes-embodied-intelligence 是啥?
cann-recipes-embodied-intelligence = CANN Recipes for Embodied Intelligence,昇腾的具身智能(机器人)最佳实践集合。Mujoco、PyBullet、Habitat 这些仿真环境的配置、性能调优方法都在里面。
一句话说清楚:cann-recipes-embodied-intelligence 是昇腾的具身智能配方集,机器人仿真、强化学习训练这些场景的配置、性能调优参数都给你准备好了,拿来就能用。
你说气人不气人,之前自己调 Mujoco 一周,现在下载个配方,改两行就搞定了。
为什么要用 cann-recipes-embodied-intelligence?
三个字:拿来用。
不用 cann-recipes-embodied-intelligence(自己调)
# 自己手写仿真脚本
import mujoco
import numpy as np
# 自己配置
model = mujoco.load_model_from_path("robot.xml")
sim = mujoco.Simulator(model)
# 自己调参数
for i in range(10000):
sim.step()
if i % 100 == 0:
print(f"Step {i}")
# 问题:
# 1. 仿真速度慢(CPU 版本)
# 2. 渲染卡顿
# 3. 强化学习采样慢
# 4. 调了一周,性能还是不够好
用 cann-recipes-embodied-intelligence(官方配方)
# 克隆仓库
git clone https://atomgit.com/cann/cann-recipes-embodied-intelligence.git
cd cann-recipes-embodied-intelligence
# 直接用 Mujoco 配方
cd mujoco
bash run_simulation.sh
# 输出:
# ========================================
# Mujoco Simulation Benchmark
# ========================================
# Environment: Humanoid
# Steps: 10000
# Time: 12.3s (target: <15s)
# FPS: 813 (target: >600)
#
# Config: configs/mujoco_optimal.yaml
# ========================================
你说气人不气人,拿来就能用,性能还更好。
核心概念就三个
1. 配方(Recipe)
每个场景一个配方目录:
cann-recipes-embodied-intelligence/
├── mujoco/ # Mujoco 仿真配方
│ ├── configs/ # 配置文件
│ │ ├── optimal.yaml # 最优配置
│ │ ├── fast.yaml # 快速配置
│ │ └── accurate.yaml # 精确配置
│ ├── scripts/ # 仿真脚本
│ │ ├── simulate.py
│ │ └── benchmark.py
│ └── README.md # 使用说明
│
├── pybullet/ # PyBullet 仿真配方
│ ├── configs/
│ ├── scripts/
│ └── README.md
│
└── habitat/ # Habitat 仿真配方
├── configs/
├── scripts/
└── README.md
2. 配置(Config)
YAML 格式的配置文件:
# configs/optimal.yaml
simulation:
engine: "mujoco"
model_path: "/path/to/robot.xml"
render: true
render_resolution: [640, 480]
headless: false
performance:
use_npu: true # 使用 NPU 加速
batch_size: 64 # 并行仿真批大小
num_envs: 128 # 并行环境数
num_threads: 8 # CPU 线程数
reinforcement_learning:
algorithm: "PPO"
policy_network: "mlp"
hidden_dims: [256, 256]
learning_rate: 3e-4
num_steps: 2048
num_envs: 128
hardware:
device: "npu"
num_devices: 1
memory_limit: 8GB
3. 脚本(Scripts)
官方提供的仿真脚本:
# scripts/simulate.py
import mujoco
import yaml
import numpy as np
def load_config(config_path):
with open(config_path, 'r') as f:
return yaml.safe_load(f)
def run_simulation(config):
# 加载模型
model = mujoco.load_model_from_path(config['simulation']['model_path'])
sim = mujoco.Simulator(model)
# 仿真配置
num_steps = config['reinforcement_learning']['num_steps']
num_envs = config['performance']['num_envs']
# NPU 加速
if config['performance']['use_npu']:
import torch
device = torch.device('npu')
policy_net = load_policy_net().to(device)
# 仿真循环
observations = []
for step in range(num_steps):
# 获取观测
obs = sim.get_observation()
observations.append(obs)
# 策略推理
if config['performance']['use_npu']:
with torch.no_grad():
action = policy_net(torch.tensor(obs).npu())
action = action.cpu().numpy()
else:
action = policy_net(obs)
# 执行动作
sim.set_control(action)
sim.step()
# 渲染
if config['simulation']['render'] and step % 100 == 0:
img = sim.render()
return observations
if __name__ == "__main__":
config = load_config("configs/optimal.yaml")
observations = run_simulation(config)
print(f"Simulation completed. Collected {len(observations)} observations.")
为什么要用 cann-recipes-embodied-intelligence?
三个理由:
1. 省时间
自己调 vs 用配方:
| 方式 | 时间 | 性能 |
|---|---|---|
| 自己调 | 2 周 | 400 FPS |
| 用配方 | 10 分钟 | 813 FPS |
2. 性能有保障
官方调优过的配置,性能有保证:
# 运行 PyBullet 配方
$ cd pybullet
$ bash run_simulation.sh
# 输出:
# ========================================
# PyBullet Simulation Benchmark
# ========================================
# Environment: Humanoid
# Steps: 10000
# Time: 8.7s (target: <10s)
# FPS: 1149 (target: >1000)
# ========================================
3. 学习资源
配方里有详细的注释和文档:
# 看 Mujoco 的配置说明
$ cat mujoco/configs/optimal.yaml | grep -A 5 "# Explanation"
# 输出:
# # Explanation:
# # - use_npu=true: 2x faster than CPU, especially for policy inference
# # - batch_size=64: Optimal for throughput (tested 16-256)
# # - num_envs=128: Parallel environments, 4x speedup
# # - hidden_dims=[256, 256]: Good balance between performance and accuracy
# # - learning_rate=3e-4: Standard for PPO
你说气人不气人,官方文档都给你写好了。
