1. 安装
pip install dslighting python-dotenv
2. 配置环境变量
创建 .env 文件:
# .env
# 指定默认使用的模型(必须设置!)
LLM_MODEL=glm-4
# 多模型配置(JSON 格式)
LLM_MODEL_CONFIGS='{
"glm-4": {
"api_key": ["your-key-1", "your-key-2"],
"api_base": "https://open.bigmodel.cn/api/paas/v4",
"temperature": 0.7,
"provider": "openai"
},
"openai/deepseek-ai/DeepSeek-V3": {
"api_key": ["sk-siliconflow-key-1", "sk-siliconflow-key-2"],
"api_base": "https://api.siliconflow.cn/v1",
"temperature": 1.0
},
"gpt-4o": {
"api_key": "sk-your-openai-api-key",
"api_base": "https://api.openai.com/v1",
"temperature": 0.7
}
}'
支持的模型提供商:
- OpenAI (GPT-4, GPT-3.5)
- 智谱 AI (GLM-4)
- SiliconFlow (DeepSeek, Qwen, Kimi 等)
- 任何兼容 OpenAI API 的服务
3. 运行任务
方式 1:全局配置(推荐用于多任务)
from dotenv import load_dotenv
load_dotenv()
import dslighting
# 配置一次,全局生效
dslighting.setup(
data_parent_dir="/path/to/data/competitions",
registry_parent_dir="/path/to/registry"
)
# 创建 Agent
agent = dslighting.Agent()
# 运行任务(只需 task_id)
result = agent.run(task_id="bike-sharing-demand")
print(f"✅ 任务完成!")
print(f"结果: {result}")
方式 2:直接路径(明确清晰)
from dotenv import load_dotenv
load_dotenv()
import dslighting
agent = dslighting.Agent()
result = agent.run(
task_id="bike-sharing-demand",
data_dir="/path/to/data/competitions/bike-sharing-demand",
registry_dir="/path/to/registry/bike-sharing-demand"
)
方式 3:内置数据集(最简单)
from dotenv import load_dotenv
load_dotenv()
import dslighting
# 无需配置,直接使用
result = dslighting.run_agent(task_id="bike-sharing-demand")
方式 4:先加载数据(灵活检查)
from dotenv import load_dotenv
load_dotenv()
import dslighting
# 先加载数据并检查
data = dslighting.load_data(
"/path/to/data/competitions/bike-sharing-demand",
registry_dir="/path/to/registry/bike-sharing-demand"
)
# 检查数据
print(data.show())
# 确认无误后运行
agent = dslighting.Agent()
result = agent.run(data)
4. 查看结果
print(f"Workspace: {result.workspace_path}")
print(f"Score: {result.score}")
🔍 Discovery API - 探索可用组件
DSLighting 2.0 提供了强大的 Discovery API,帮助你探索和了解所有可用的 prompts 和 operators。
快速探索
import dslighting
# 一键查看所有可用组件
dslighting.explore()

使用场景
场景 1: 探索可用的 workflow prompts
# 查看所有 AIDE workflow 的 prompts
from dslighting.prompts import get_prompt_info
aide_prompts = [
"create_improve_prompt",
"create_debug_prompt"
]
for prompt_name in aide_prompts:
info = get_prompt_info(prompt_name)
print(f"\n{prompt_name}:")
print(f" Description: {info['description']}")
print(f" Inputs: {[inp['name'] for inp in info['inputs']]}")
场景 2: 选择合适的 operator
# 比较 LLM operators
from dslighting.operators import get_operator_info
llm_ops = ["PlanOperator", "GenerateCodeAndPlanOperator", "ReviewOperator"]
for op_name in llm_ops:
info = get_operator_info(op_name)
print(f"\n{op_name}:")
print(f" Description: {info['description']}")
print(f" Input: {info['inputs']}")
print(f" Output: {info['outputs']}")
场景 3: 学习如何使用组件
# 获取完整的使用示例
info = get_prompt_info("create_improve_prompt")
print(info['example']) # 复制粘贴即可运行
info = get_operator_info("ReviewOperator")
print(info['example']) # 包含完整的初始化和调用代码
📖 核心概念
数据系统
DSLighting 使用统一的数据管理系统:
- LoadedData:核心数据容器,封装数据集和任务配置
- TaskDetection:自动识别任务类型(kaggle, open_ended, datasci)
- Registry:管理任务配置和评分规则
查看数据结构:
data = dslighting.load_data(...)
print(data.show())
输出包括:
- 任务 ID 和类型
- 数据目录结构
- CSV 文件信息
- 任务描述和评估指标
Agent 配置
# 使用默认配置
agent = dslighting.Agent()
# 等价于:
agent = dslighting.Agent(
workflow="aide", # 工作流类型
model="gpt-4o-mini", # LLM 模型(从 .env 读取)
temperature=0.7, # 生成温度
max_iterations=5 # 最大迭代次数
)
🔧 高级配置
自定义任务
创建自己的数据科学任务:
目录结构:
your-project/
├── data/competitions/
│ └── your-task-name/
│ └── prepared/
│ ├── public/ # train.csv, test.csv, sampleSubmission.csv
│ └── private/ # test_answer.csv
│
└── registry/
└── your-task-name/
├── config.yaml # 任务配置
├── description.md # 任务描述
└── grade.py # 评分脚本(可选)
config.yaml 示例:
id: your-task-name
name: Your Task Display Name
competition_type: simple
awards_medals: false
description: your-task-name/description.md
dataset:
answers: your-task-name/prepared/private/test_answer.csv
sample_submission: your-task-name/prepared/public/sampleSubmission.csv
grader:
name: rmsle # 或 accuracy, f1, mae 等
运行自定义任务:
result = agent.run(
task_id="your-task-name",
data_dir="/path/to/data/competitions",
registry_dir="/path/to/registry"
)
常见问题
Q: 为什么显示 "Score: N/A"?
A: 这是 DSLighting 的已知问题。自动评分功能当前未启用,需要手动评分:
from pathlib import Path
from mlebench.grade import grade_csv
from dsat.benchmark.mle import MLEBenchmarkRegistry
registry_dir = Path(dslighting.__file__).parent / "registry"
registry = MLEBenchmarkRegistry(registry_dir=str(registry_dir))
competition = registry.get_competition("bike-sharing-demand")
submission_files = list(result.workspace_path.glob("sandbox/submission_*.csv"))
if submission_files:
report = grade_csv(submission_files[0], competition)
print(f"✅ 实际 Score: {report.score}")
Q: load_dotenv() 是必须的吗?
A: 是的!必须在导入 dslighting 之前调用 load_dotenv() 来加载 .env 配置。

- 发布说明 - DSLighting 2.1.0 更新内容
🎉 最新版本更新
DSLighting 2.3.5 (2025-01-20) - 🔧 Import Error Fix
✅ 完整版本:包含所有四个 bug 修复
Bug #4: AgentResult 导入错误(Critical)✓ 已修复
问题:ImportError: cannot import name 'AgentResult' from 'dslighting.api.agent'
影响:完全无法导入 dslighting 包
根本原因:v2.3.4 重写了 dslighting/api/agent.py,但忘记添加 AgentResult 类定义
修复:
- 在
dslighting/api/agent.py中添加了完整的AgentResultdataclass 定义 AgentResult包含所有必要的字段:success, output, score, cost, duration, workspace_path, error, metadata- 添加了友好的
__repr__方法用于显示结果摘要
技术细节:
@dataclass
class AgentResult:
"""Result of running an Agent on a data science task."""
success: bool
output: any
cost: float = 0.0
duration: float = 0.0
score: Optional[float] = None
artifacts_path: Optional[Path] = None
workspace_path: Optional[Path] = None
error: Optional[str] = None
metadata: dict = field(default_factory=dict)
包含的所有修复:
- ✓ Bug #1:
load_data()不支持数据集名称(v2.3.3 修复) - ✓ Bug #2: 安装失败(v2.3.3 修复)
- ✓ Bug #3: Agent 初始化错误(v2.3.4 修复)
- ✓ Bug #4: AgentResult 导入错误(v2.3.5 修复)
升级建议:
- 强烈推荐所有用户立即升级到 v2.3.5
- 如果你遇到
ImportError或无法导入 dslighting,请立即升级 - v2.3.5 是目前最稳定的版本,修复了所有已知的关键 bug
DSLighting 2.3.4 (2025-01-20) - 🔧 Agent Initialization Fix
✅ 完整版本:包含所有三个 bug 修复
Bug #3: Agent 初始化错误(Critical)✓ 已修复
问题:Agent(workflow="aide", model="...", max_iterations=1) 报错 TypeError: AIDEWorkflow.__init__() got an unexpected keyword argument 'model'
影响:无法通过 dslighting.Agent() 创建 agent 实例
根本原因:Agent 类直接实例化 workflow,传递了错误的参数。AIDEWorkflow.__init__() 期望 operators, services, agent_config,但 Agent 传递了 model
修复:
- 完全重构了
dslighting/api/agent.py,改用工厂模式(Factory Pattern) - 现在使用
AIDEWorkflowFactory,AutoKaggleWorkflowFactory等工厂类来正确创建 workflow - 工厂类正确处理
model,api_key,api_base,temperature等参数
技术细节:
# 修复前(错误)
self._agent = AIDE(model=model, **kwargs) # TypeError!
# 修复后(正确)
self._factory = AIDEWorkflowFactory(
model=model,
api_key=api_key,
api_base=api_base,
provider=provider,
temperature=temperature,
timeout=timeout,
keep_workspace=keep_workspace
)
使用示例:
from dotenv import load_dotenv
load_dotenv()
import dslighting
# ✅ 现在可以正常工作
agent = dslighting.Agent(
workflow="aide",
model="gpt-4o",
max_iterations=1
)
result = agent.run(task_id="bike-sharing-demand")
print(f"✅ Success: {result.success}")
包含的所有修复:
- ✓ Bug #1:
load_data()不支持数据集名称(v2.3.3 修复) - ✓ Bug #2: 安装失败(v2.3.3 修复)
- ✓ Bug #3: Agent 初始化错误(v2.3.4 修复)
升级建议:
- 强烈推荐所有用户升级到 v2.3.4
- 如果你遇到
TypeError或ValueError: Data path not found,请立即升级 - v2.3.4 是目前最稳定的版本
DSLighting 2.3.3 (2025-01-20) - 🔧 Critical Bug Fixes
⚠️ 重要:此版本修复了两个严重bug
Bug #1: 安装失败(Critical)✓ 已修复
问题:v2.3.2 无法通过 pip 安装,因为 setup.py 尝试读取 PIP_DOC/README_PIP.md 时失败
影响:完全无法安装或升级 DSLighting
修复:
- 添加了
try-except错误处理 - 创建了
MANIFEST.in文件确保 README 文件被包含在源码包中 - 现在即使 README 文件缺失也能成功安装
Bug #2: load_data() 不支持数据集名称(High)✓ 已修复
问题:load_data("bike-sharing-demand") 报错 ValueError: Data path not found
影响:用户无法使用文档中描述的简化 API
修复:
- 移除了数据集目录检查代码的
except块限制 - 改进了错误提示,列出所有可用的内置数据集
- 现在支持通过数据集名称加载数据
使用示例:
import dslighting
# ✅ 现在这两种方式都可以正常工作:
# 方式1:使用数据集名称(推荐)
data = dslighting.load_data("bike-sharing-demand")
# 方式2:使用完整路径
data = dslighting.load_data("/path/to/bike-sharing-demand")
# 方式3:错误时显示可用数据集
data = dslighting.load_data("unknown-dataset")
# ValueError: Dataset 'unknown-dataset' not found.
# Available built-in datasets: bike-sharing-demand
# Or provide an explicit path to your data.
升级建议:
- 如果无法安装 v2.3.2,请直接升级到 v2.3.3
- 如果已安装 v2.3.2,建议升级到 v2.3.3 以获得完整的 bug 修复
DSLighting 2.3.2 (2025-01-20) - ⚠️ Broken Release
注意:此版本无法安装,已被 v2.3.3 替代
DSLighting 2.3.1
Hotfix:自动修复 BaseWorkflowFactory 中不完整的 io_instructions
DSLighting 2.1.0
