## 快速使用
### 首先，填写LLM配置
```
import os, sys
import openai

# llm config
os.environ["API_BASE_URL"] = OPENAI_API_BASE
os.environ["OPENAI_API_KEY"] = "sk-xxx"
openai.api_key = "sk-xxx"
# os.environ["OPENAI_PROXY"] = "socks5h://127.0.0.1:13659"
```

### 然后设置LLM配置和向量模型配置
```
from coagent.llm_models.llm_config import EmbedConfig, LLMConfig

llm_config = LLMConfig(
    model_name="gpt-3.5-turbo", model_device="cpu",api_key=os.environ["OPENAI_API_KEY"], 
    api_base_url=os.environ["API_BASE_URL"], temperature=0.3
    )

embed_config = EmbedConfig(
    embed_engine="model", embed_model="text2vec-base-chinese", 
    embed_model_path="D://project/gitlab/llm/external/ant_code/Codefuse-chatbot/embedding_models/text2vec-base-chinese"
    )
```

### 最后选择一个已有场景进行执行
```
from coagent.tools import toLangchainTools, TOOL_DICT, TOOL_SETS
from coagent.connector.phase import BasePhase
from coagent.connector.schema import Message

# 选择一个已实现得场景进行执行

# 如果需要做一个数据分析，需要将数据放到某个工作目录，同时指定工作目录（也可使用默认目录）
import shutil
source_file = 'D://project/gitlab/llm/external/ant_code/Codefuse-chatbot/jupyter_work/book_data.csv'
shutil.copy(source_file, JUPYTER_WORK_PATH)

# 选择一个场景
phase_name = "baseGroupPhase"
phase = BasePhase(
    phase_name, embed_config=embed_config, llm_config=llm_config, 
)

# round-1 需要通过代码解释器来完成
query_content = "确认本地是否存在employee_data.csv，并查看它有哪些列和数据类型;然后画柱状图"
query = Message(
    role_name="human", role_type="user", tools=[],
    role_content=query_content, input_query=query_content, origin_query=query_content,
    )

# phase.pre_print(query)  # 该功能用于预打印 Agents 执行链路的Prompt
output_message, output_memory = phase.step(query)
print(output_memory.to_str_messages(return_all=True, content_key="parsed_output_list"))

# round-2 需要执行工具
tools = toLangchainTools([TOOL_DICT[i] for i in TOOL_SETS if i in TOOL_DICT])

query_content = "帮我确认下127.0.0.1这个服务器的在10点是否存在异常，请帮我判断一下"
query = Message(
    role_name="human", role_type="user", tools=tools,
    role_content=query_content, input_query=query_content, origin_query=query_content,
    )

# phase.pre_print(query)  # 该功能用于预打印 Agents 执行链路的Prompt
output_message, output_memory = phase.step(query)
print(output_memory.to_str_messages(return_all=True, content_key="parsed_output_list"))

```
