来个openmanus的浅入门
前阵子一个manus在目前的所谓人工智能圈子里甚至普通人视野里都很火了，宣称是什么中国的下一个deepseek时刻，首先deepseek是经过了v1，v2等一系列版本的迭代之后，并且一直是在技术上非常花功夫的，有种宝剑锋从磨砺出的感觉，而这个manus听着更像是个蹭热度的
这不没出多久有个openmanus宣称用了三小时做了个开源的复刻版，那么我们就来简单体验下，从概念上来说吧，有点类似于做了个mcp的规划和整合调用
我个人理解好像没有到改变世界的程度
首先呢我们先来安装下
可以使用conda，也可以使用uv，以conda举例，先建个环境1
2conda create -n open_manus python=3.12
conda activate open_manus
然后来clone下代码仓库1
2git clone https://github.com/mannaandpoem/OpenManus.git
cd OpenManus
接着再安装下依赖1
pip install -r requirements.txt
这里可以借助下源替换加速，临时使用可以这样子 pip install -i https://mirrors.tuna.tsinghua.edu.cn/pypi/web/simple some-package , 这里需要安装蛮久的，可能也说明了这是个依赖于很多现成库的工具
第二阶段配置
配置其实也是常规的，依赖于大模型，那么要不就是自己部署提供api，要不就是去火山引擎或者其他大模型api提供商搞个api（免费额度用完要自己付费的）1
cp config/config.example.toml config/config.toml
这一步其实跟之前使用chatbox连接火山的配置类似
因为像国外很多都还是openai的接口服务，这边就需要改用成国内可用的1

model = "deepseek-r1-250120" # The LLM model to use
base_url = "https://ark.cn-beijing.volces.com/api/v3" # API endpoint URL
api_key = "xxxxxxxxxxxxxxxxxx" # Your API key
max_tokens = 8192 # Maximum number of tokens in the response
temperature = 0.0
模型可以用deepseek-r1，不过要注意是什么时间版本的，否则也会访问不到
然后我们就可以运行1
python main.py
来运行openmanus，我们简单问个问题1
明天杭州的天气怎么样，给出个穿衣指南

根据这个返回可以看到它做了些啥，主要是规划步骤和选择调用的工具，相对来说没有特别的，playwright我就不去搞了，浏览器那套
