## Quick Start
Attention：
Testing has only been conducted on GPT-3.5-turbo and higher models. 
The models need to possess strong command-following capabilities. 
It is recommended to test with more powerful models like qwen-72b, openai, etc.

### First, set up the LLM configuration
```
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"
```

### Next, configure the LLM settings and vector model
```
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"
    )
```

### Finally, choose a pre-existing scenario to execute
```
from coagent.tools import toLangchainTools, TOOL_DICT, TOOL_SETS
from coagent.connector.phase import BasePhase
from coagent.connector.schema import Message

# Copy the data to a working directory; specify the directory if needed (default can also be used)
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)

# Choose a scenario to execute
phase_name = "baseGroupPhase"
phase = BasePhase(
    phase_name, embed_config=embed_config, llm_config=llm_config, 
)

# round-1: Use a code interpreter to complete tasks
query_content = "Check if 'employee_data.csv' exists locally, view its columns and data types; then draw a bar chart"
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)  # This function is used to preview the Prompt of the Agents' execution chain
output_message, output_memory = phase.step(query)
print(output_memory.to_str_messages(return_all=True, content_key="parsed_output_list"))

# round-2: Execute tools
tools = toLangchainTools([TOOL_DICT[i] for i in TOOL_SETS if i in TOOL_DICT])

query_content = "Please check if there were any issues with the server at 127.0.0.1 at 10 o'clock; help me make a judgment"
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)  # This function is used to preview the Prompt of the Agents' execution chain
output_message, output_memory = phase.step(query)
print(output_memory.to_str_messages(return_all=True, content_key="parsed_output_list"))

```

## Phase Introduction and Usage

Below are some specific Phase introduced and how to use them.

Feel free to brainstorm and create some interesting cases.

### baseGroupPhase
The group usage Phase in autogen

```
# Copy the data to a working directory; specify the directory if needed (default can also be used)
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)

# Set the log level to control the printing of the prompt, LLM output, or other information
os.environ["log_verbose"] = "0"

phase_name = "baseGroupPhase"
phase = BasePhase(
    phase_name, embed_config=embed_config, llm_config=llm_config, 
)

# round-1
query_content = "Check if 'employee_data.csv' exists locally, view its columns and data types; then draw a bar chart"

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) # This function is used to preview the Prompt of the Agents' execution chain
output_message, output_memory = phase.step(query)
print(output_memory.to_str_messages(return_all=True, content_key="parsed_output_list"))
```
