具体实现示例

基本配置类

# config.py
from dataclasses import dataclass
from typing import Optional, List, Tuple
@dataclass
class OpenClawConfig:
    # 数据相关
    data_root: str = "./data"
    batch_size: int = 16
    num_workers: int = 4
    # 模型相关
    model_name: str = "OpenClawNet"
    backbone: str = "resnet34"
    input_size: Tuple[int, int] = (224, 224)

    # 训练相关
    lr: float = 1e-3
    weight_decay: float = 1e-4
    epochs: int = 200
    warmup_epochs: int = 5
    # 抓取参数
    gripper_width: float = 0.08  # 米
    force_threshold: float = 10.0  # 牛顿
    # 硬件
    device: str = "cuda"
    seed: int = 42
    def __post_init__(self):
        # 自动计算其他参数
        pass

    "metrics": ["precision", "recall", "f1_score"],

}

环境配置文件

# .env 或 settings.py
import os
from pathlib import Path
class Settings:
    # 路径配置
    BASE_DIR = Path(__file__).parent.parent
    DATA_DIR = BASE_DIR / "data"
    CHECKPOINT_DIR = BASE_DIR / "checkpoints"
    LOG_DIR = BASE_DIR / "logs"
    # 模型参数
    MODEL_CONFIG = {
        'gripper_type': 'parallel_jaw',
        'max_opening': 0.1,  # 最大开口,单位米
        'finger_length': 0.05,
        'contact_points': 4,
        'torque_limit': 5.0
    }
    # 训练参数
    TRAIN_CONFIG = {
        'early_stopping': {
            'patience': 20,
            'min_delta': 0.001
        },
        'mixed_precision': True,
        'gradient_accumulation_steps': 2
    }
    # 数据集特定参数
    DATASET_CONFIG = {
        'graspnet': {
            'camera': 'kinect',
            'scene_split': [190, 50],
            'num_views': 256
        },
        'cornell': {
            'split_ratio': 0.8,
            'image_size': (480, 640)
        }
    }

命令行参数配置

# train.py 中使用argparse
import argparse
def parse_args():
    parser = argparse.ArgumentParser(description='OpenClaw Training')
    # 数据参数
    parser.add_argument('--dataset', type=str, default='graspnet',
                        choices=['graspnet', 'cornell', 'jacquard'])
    parser.add_argument('--data-path', type=str, default='./data')
    # 模型参数
    parser.add_argument('--model', type=str, default='openclaw',
                        choices=['openclaw', 'graspnet', 'ggcnn'])
    parser.add_argument('--backbone', type=str, default='resnet50')
    parser.add_argument('--input-size', type=int, default=224)
    # 训练参数
    parser.add_argument('--epochs', type=int, default=100)
    parser.add_argument('--batch-size', type=int, default=32)
    parser.add_argument('--lr', type=float, default=0.001)
    # 硬件参数
    parser.add_argument('--gpu', type=str, default='0')
    parser.add_argument('--workers', type=int, default=4)
    return parser.parse_args()

配置最佳实践

  1. 分层配置

    • 默认配置(基础配置)
    • 实验特定配置(覆盖默认)
    • 运行时配置(命令行参数)
  2. 环境特定配置

    # config/production.yaml
    # config/development.yaml
    # config/test.yaml
  3. 动态配置加载

    import yaml
    import json
    from easydict import EasyDict

def load_config(config_path): with open(config_path, 'r') as f: if config_path.endswith('.yaml') or config_path.endswith('.yml'): config = yaml.safe_load(f) elif config_path.endswith('.json'): config = json.load(f)

# 转换为EasyDict以便点号访问
return EasyDict(config)

## 常用配置项说明
| 配置项 | 说明 | 典型值 |
|--------|------|--------|
| `model.type` | 模型架构 | `resnet50`, `pointnet++`, `transformer` |
| `data.augmentation` | 数据增强策略 | `color_jitter`, `random_rotate`, `random_crop` |
| `training.lr_scheduler` | 学习率调度器 | `step`, `cosine`, `plateau` |
| `inference.nms` | 非极大值抑制 | `true/false` |
| `robot.gripper_type` | 夹爪类型 | `parallel_jaw`, `vacuum`, `three_finger` |
根据您的具体需求(仿真环境、真实机器人、数据集类型等),可能需要调整这些配置参数,您需要哪种类型的配置文件?我可以提供更具体的示例。
