Project description

TiMEM Python SDK

Time-based Memory Management and Rule Learning Toolkit

TiMEM SDK 是一个强大的 Python 客户端库,用于与 TiMEM Engine API 交互,提供记忆管理、通用规则学习和用户画像计算等功能。

特性

  • 通用规则学习:从场景/结果中学习可复用规则
  • 规则召回:基于场景、上下文、标签和过滤条件召回相关规则
  • 记忆管理:支持 L1-L5 分层记忆的增删改查
  • 用户画像:从 L5 级别记忆计算用户画像
  • 同步/异步支持:完整的同步和异步 API 封装
  • 批量操作:支持批量记忆写入提升效率
  • 自动重试:内置请求重试机制保证可靠性

安装

pip install timem-ai

或从源码安装:

git clone https://github.com/TiMEM-AI/timem-sdk-python.git
cd timem-sdk-python
pip install -e .

快速开始

规则学习门面与 Memory 保持同样的导出风格:Rules / AsyncRules 是正式类名,rules / async_rules 是小写快捷别名。

from timem import Rules, AsyncRules, rules, async_rules

同步客户端

from timem import Rules, TiMEMClient

# 1. 规则学习:从单条场景/结果学习通用规则
rules = Rules(
    api_key="your-api-key",
    base_url="http://localhost:8001",
)

learned = rules.learn(
    situation_text="候选人项目经历影响力描述比较笼统",
    outcome_text="要求补充量化指标和个人贡献边界",
    attributes={"scene": "resume_review", "role": "backend"},
    suggested_tags=["resume", "project_impact"],
    user_id="user-123",
    agent_id="hire",
)
print(learned["rule_id"])

# 2. 规则召回:根据当前场景召回相关规则
recalled = rules.recall(
    situation_text="评估 Python 后端候选人的项目经历",
    context_text="候选人只写了负责系统开发,缺少指标和业务结果",
    mode="auto",
    filters={"role": "backend"},
    top_k=5,
    user_id="user-123",
    agent_id="hire",
)
print(f"Recalled {recalled['count']} rules")

# 3. 添加记忆
client = TiMEMClient(api_key="your-api-key", base_url="http://localhost:8001")
memory = client.add_memory(
    user_id=12345,
    domain="aicv",
    content={
        "type": "interaction",
        "action": "resume_analysis",
        "context": {"job": "软件工程师"},
    },
    layer_type="L1",
    tags=["resume", "analysis"],
)

异步客户端

import asyncio
from timem import AsyncRules, AsyncTiMEMClient

async def main():
    async with AsyncRules(api_key="your-api-key", base_url="http://localhost:8001") as rules:
        learned = await rules.learn(
            situation_text="候选人项目经历影响力描述比较笼统",
            outcome_text="要求补充量化指标和个人贡献边界",
            suggested_tags=["resume", "project_impact"],
            user_id="user-123",
            agent_id="hire",
        )

        recalled = await rules.recall(
            situation_text="评估 Python 后端候选人的项目经历",
            context_text="候选人只写了负责系统开发,缺少指标和业务结果",
            mode="auto",
            top_k=5,
            user_id="user-123",
            agent_id="hire",
        )

    async with AsyncTiMEMClient(api_key="your-api-key", base_url="http://localhost:8001") as client:
        memories = [
            {"user_id": 12345, "domain": "aicv", "content": {"action": "view_job", "job_id": 1}},
            {"user_id": 12345, "domain": "aicv", "content": {"action": "apply_job", "job_id": 1}},
        ]
        results = await client.batch_add_memories(memories)

asyncio.run(main())

API 文档

通用规则学习

Rules.learn() / TiMEMClient.learn_rule()

从单条场景/结果中学习一条可复用规则。

rules.learn(
    situation_text="场景描述",
    outcome_text="这次应沉淀下来的处理经验",
    attributes={"scene": "resume_review"},
    suggested_tags=["resume"],
    user_id="default",
    agent_id="default",
)

Rules.recall() / TiMEMClient.recall_rules()

根据当前场景召回相关规则。

rules.recall(

    ]
    results = await client.batch_add_memories(memories)

异常处理

from timem import Rules, TiMEMError, AuthenticationError, APIError, ValidationError

try:
    rules = Rules(api_key="your-key")
    result = rules.learn(situation_text="场景", outcome_text="经验")
except ValidationError as e:
    print(f"验证错误: {e}")
except AuthenticationError as e:
    print(f"认证失败: {e}")
except APIError as e:
    print(f"API错误 [{e.status_code}]: {e}")
except TiMEMError as e:
    print(f"TiMEM错误: {e}")

配置选项

client = TiMEMClient(
    api_key="your-api-key",
    base_url="http://localhost:8001",  # TiMEM Engine URL
    timeout=60.0,                       # 请求超时(秒)
)

async_client = AsyncTiMEMClient(
    api_key="your-api-key",
    base_url="http://localhost:8001",
    timeout=60.0,
    max_retries=3,                      # 最大重试次数
    retry_delay=1.0,                    # 重试延迟(秒)
)

开发指南

安装开发依赖

pip install -r requirements-dev.txt

运行测试

pytest tests/

构建发布

python -m build
python -m twine upload dist/*

架构说明

TiMEM SDK 遵循以下设计原则:

  1. 简洁接口:规则学习通过 Rules.learn() / learn_rule() 显式表达场景和结果
  2. 智能召回:基于场景、标签、过滤条件和上下文召回相关规则
  3. 分层记忆:支持 L1-L5 五层记忆管理
  4. 异步优先:充分利用异步编程提升性能
  5. 容错设计:自动重试和异常处理
