作为向量数据库的佼佼者,Milvus 适用于各种需要借助高效和可扩展向量搜索功能的 AI 应用。
举个例子,如果想要搭建一个负责聊天机器人数据管理流程,Milvus 必然是首选向量数据库。那么如何让这个应用程序开发变得易于管理及更好理解,那就需要借助 Towhee(https://towhee.io/)了。Towhee 是一个新兴的机器学习(ML)框架,可以简化了实现和编排复杂 ML 模型的过程。
接下来我将介绍如何通过 Python 使用 Milvus + Towhee 搭建一个基础的 AI 聊天机器人。本文会重点讲解如何处理、分析非结构化数据及存储和查询向量数据。
01.设置环境
首先,创建一个 Python 虚拟环境来运行聊天机器人。
以下是 Linux shell session(会话)。借助 Shell session 创建并激活环境,将 pip 升级到最新版本。

02.搭建聊天机器人
一切准备就绪后,就可以搭建聊天机器人了。
文档存储
机器人需要存储文档块以及使用 Towhee 提取出的文档块向量。在这个步骤中,我们需要用到 Milvus。
安装轻量版 Milvus Lite,使用以下命令运行 Milvus 服务器:
(chatbot_venv) [egoebelbecker@ares milvus_chatbot]$ milvus-server
__ _________ _ ____ ______
/ |/ / _/ /| | / / / / / __/
/ /|_/ // // /_| |/ / /_/ /
/_/ /_/___/____/___/____/___/ {Lite}
Welcome to use Milvus!
Version: v2.2.12-lite
Process: 139309
Started: 2023-07-31 12:43:43
Config: /home/egoebelbecker/.milvus.io/milvus-server/2.2.12/configs/milvus.yaml
Logs: /home/egoebelbecker/.milvus.io/milvus-server/2.2.12/logs
Ctrl+C to exit …
或者,运行 Notebook 中的代码:
from milvus import default_server
# 启动 Milvus 服务
default_server.start()
# 停止 Milvus 服务
default_server.stop()
设置应用变量并获取 OpenAI API 密钥
接下来,设置变量并清理旧的 SQLite 文件,我们将用 SQLite 存储聊天历史记录。
-
MILVUS_URI – Milvus 服务器连接信息,解析为主机和端口。
-
MILVUS_HOST – Milvus 运行的主机。
-
MILVUS_PORT – 服务器监听的端口。
-
DROP_EXIST – 在启动时删除现有的 Milvus 集合。
-
EMBED_MODEL – 用于生成 embedding 向量的 sentence_transformers模型
-
COLLECTION_NAME – 用于存储向量数据的 Milvus collection 名称
-
DIM – 模型生成的文本向量维度
-
OPENAI_API_KEY – 大语言模型(LLM) API 的密钥
import getpass
import os
MILVUS_URI = 'http://localhost:19530'
[MILVUS_HOST, MILVUS_PORT] = MILVUS_URI.split('://')[1].split(':')
DROP_EXIST = True
EMBED_MODEL = 'all-mpnet-base-v2'
COLLECTION_NAME = 'chatbot_demo'
DIM = 768
OPENAI_API_KEY = getpass.getpass('Enter your OpenAI API key: ')
if os.path.exists('./sqlite.db'):
os.remove('./sqlite.db')
运行上述代码定义变量并输入 OpenAI API 密钥。
示例流水线(pipeline)
接下来,需要下载数据并存储在 Milvus 中。不过在此之前,先学习一下如何使用 pipeline 处理非结构化数据。
我会用 Towhee 官网主页作为文档来源的示例来进行演示,大家也可以尝试其他不同文档网站,了解 pipeline 如何处理不同的数据集。
以下代码使用 Towhee pipeline:
-
input – 创建新 pipeline,传入源数据。
-
map – 使用 ops.text_loader() 解析 URL 并将其映射为 ‘doc’。
-
flat_map – 使用 ops.text_splitter() 将文档拆分成多个片段,以便后续存储。
-
output – 选择数据输出,准备就绪可以使用。
将此 pipeline 传入 DataCollection 观察其工作原理。
from towhee import pipe, ops, DataCollectionpipe_load = (
from towhee import pipe, ops, DataCollection
pipe_load = (
pipe.input('source')
.map('source', 'doc', ops.text_loader())
.flat_map('doc', 'doc_chunks', ops.text_splitter(chunk_size=300))
.output('source', 'doc_chunks')
)
DataCollection(pipe_load('https://towhee.io')).show()
以下为输出:
示例 Embedding pipeline
接着,参考以下示例 embedding pipeline 将这些文档块转化为向量。pipeline 通过 map() 在每个文档块上运行 ops.sentence_embedding.sbert()。在示例中,我们传入了1 个文本块。
pipe_embed = (
pipe.input('doc_chunk')
.map('doc_chunk', 'vec', ops.sentence_embedding.sbert(model_name=EMBED_MODEL))
.map('vec', 'vec', ops.np_normalize())
.output('doc_chunk', 'vec')
)
text = '''SOTA Models
We provide 700+ pre-trained embedding models spanning 5 fields (CV, NLP, Multimodal, Audio, Medical), 15 tasks, and 140+ model architectures.
These include BERT, CLIP, ViT, SwinTransformer, data2vec, etc.
'''
DataCollection(pipe_embed(text)).show()
运行此代码查看这个 pipeline 如何将单个文档片段转换成向量。
设置 Milvus
创建 1 个 Collection 来存储数据。
以下代码中,我们使用 MILVUS_HOST 和 MILVUS_PORT 连接至 Milvus,删除所有现有 Collection ,并定义了 create_collection() 函数以创建 1 个全新的 Collection。
新 Collection 的 Schema 如下所示:
-
id – 标识符,数据类型为整数。
-
embedding – 向量,数据类型为浮点向量。
-
text – 向量对应的文档块文本,数据类型为字符串。
from pymilvus import (
connections, utility, Collection,
CollectionSchema, FieldSchema, DataType
)
def create_collection(collection_name):
connections.connect(host=MILVUS_HOST, port=MILVUS_PORT)
has_collection = utility.has_collection(collection_name)
if has_collection:
collection = Collection(collection_name)
if DROP_EXIST:
collection.drop()
else:
return collection
# 创建 collection
fields = [
FieldSchema(name='id', dtype=DataType.INT64, is_primary=True, auto_id=True),
FieldSchema(name='embedding', dtype=DataType.FLOAT_VECTOR, dim=DIM),
FieldSchema(name='text', dtype=DataType.VARCHAR, max_length=500)
]
schema = CollectionSchema(
fields=fields,
description="Towhee demo",
enable_dynamic_field=True
)
collection = Collection(name=collection_name, schema=schema)
index_params = {
'metric_type': 'IP',
'index_type': 'IVF_FLAT',
'params': {'nlist': 1024}
}
collection.create_index(
field_name='embedding',
index_params=index_params
)
return collection
插入 Pipeline
现在,将文本向量插入 Milvus。
以下代码可以:
-
创建新 Collection
-
加载新文档数据
-
将新文档切块
-
使用 EMBED_MODEL 为文本快生成向量
-
将文本块向量和对应文本块数据插入到 Milvus
load_data = (
pipe.input('collection_name', 'source')
.map('collection_name', 'collection', create_collection)
.map('source', 'doc', ops.text_loader())
.flat_map('doc', 'doc_chunk', ops.text_splitter(chunk_size=300))
.map('doc_chunk', 'vec', ops.sentence_embedding.sbert(model_name=EMBED_MODEL))
.map('vec', 'vec', ops.np_normalize())
.map(('collection_name', 'vec', 'doc_chunk'), 'mr',
ops.ann_insert.osschat_milvus(host=MILVUS_HOST, port=MILVUS_PORT))
.output('mr')
)
通过以下代码,我们将 Frodo Baggins 的百科页面内容转化为文本快向量并插入到 Milvus 中。
project_name = 'towhee_demo'
data_source = 'https://en.wikipedia.org/wiki/Frodo_Baggins'
mr = load_data(COLLECTION_NAME, data_source)
print('Doc chunks inserted:', len(mr.to_list()))
最终一共插入 408 个本文块向量:

Doc chunks inserted: 408
03.检索知识库
Milvus 中已经存储了文本块向量,现在可以进行向量查询了。
以下函数创建了 1 个查询 pipeline。注意,这是本教程中最为关键的一个步骤!
ops.ann_search.osschat_milvus(host=MILVUS_HOST, port=MILVUS_PORT,
**{'metric_type': 'IP', 'limit': 3, 'output_fields': ['text']}))
OSSChat_milvus(https://towhee.io/ann-search/osschat-milvus) 查询 Milvus 向量数据库中与查询文本相匹配的文档片段。
以下为整个查询 pipeline 代码:
pipe_search = (
pipe.input('collection_name', 'query')
.map('query', 'query_vec', ops.sentence_embedding.sbert(model_name=EMBED_MODEL))
.map('query_vec', 'query_vec', ops.np_normalize())
.map(('collection_name', 'query_vec'), 'search_res',
ops.ann_search.osschat_milvus(host=MILVUS_HOST, port=MILVUS_PORT,
**{'metric_type': 'IP', 'limit': 3, 'output_fields': ['text']}))
.flat_map('search_res', ('id', 'score', 'text'), lambda x: (x[0], x[1], x[2]))
.output('query', 'text', 'score')
)
现在,可以尝试查询以下问题:
query = 'Who is Frodo Baggins?'
DataCollection(pipe_search(project_name, query)).show()
不难发现,我们使用的模型返还了 3 个相匹配的结果(注:前面 ann_search.osschat_milvus 中指定了 limit=3):
04.加入大语言模型(LLM)
接着,需要在聊天机器人中加入 LLM。这样,用户就可以和聊天机器人开展对话了。本示例中,我们将使用 OpenAI ChatGPT 背后的模型服务:GPT-3.5。
聊天记录
为了使 LLM 回答更准确,我们需要存储用户和机器人的聊天记录,并在查询时调用这些记录,可以用 SQLite 实现聊天记录的管理。
以下函数用于调取聊天记录:
query = 'Who is Frodo Baggins?' DataCollection(pipe_search(project_name, query)).show()
以下函数用户存储聊天记录:
pipe_add_history = ( pipe.input('collection_name', 'session', 'question', 'answer') .map(('collection_name', 'session', 'question', 'answer'), 'history', ops.chat_message_histories.sql(method='add')) .output('history') )
LLM 查询 Pipeline
搭建一个 Pipeline 将查询传递至 LLM 中。
这个 LLM 查询 Pipeline 可以:
-
根据用户查询问题搜索 Milvus 向量数据库
-
调取并存储当前聊天记录
-
将用户查询问题、Milvus 搜索结果、聊天记录三者一并传入 ChatGPT
-
记录本轮问题和答案
-
返回最终回答
chat = (
pipe.input('collection_name', 'query', 'session')
.map('query', 'query_vec', ops.sentence_embedding.sbert(model_name=EMBED_MODEL))
.map('query_vec', 'query_vec', ops.np_normalize())
.map(('collection_name', 'query_vec'), 'search_res',
ops.ann_search.osschat_milvus(host=MILVUS_HOST,
port=MILVUS_PORT,
**{'metric_type': 'IP', 'limit': 3, 'output_fields': ['text']}))
.map('search_res', 'knowledge', lambda y: [x[2] for x in y])
.map(('collection_name', 'session'), 'history', ops.chat_message_histories.sql(method='get'))
.map(('query', 'knowledge', 'history'), 'messages', ops.prompt.question_answer())
.map('messages', 'answer', ops.LLM.OpenAI(api_key=OPENAI_API_KEY,
model_name='gpt-3.5-turbo',
temperature=0.8))
.map(('collection_name', 'session', 'query', 'answer'), 'new_history', ops.chat_message_histories.sql(method='add'))
.output('query', 'history', 'answer', )
)
在连接至图形用户界面(GUI)前,我们需要先测试以下这个 Pipeline。
new_query = 'Where did Frodo take the ring?'
DataCollection(chat(COLLECTION_NAME, new_query, session_id)).show()
以下为输出和结果:
恭喜你!这个 Pipeline 搭建成功了!接下来可以搭建 Gradio 界面吧!
Gradio 界面
首先,需要一些函数通过 UUID 来创建 session ID ,接受并响应界面上的用户查询。
import uuidimport io
def create_session_id():
uid = str(uuid.uuid4())
suid = ''.join(uid.split('-'))
return 'sess_' + suid
def respond(session, query):
res = chat(COLLECTION_NAME, query, session).get_dict()
answer = res['answer']
response = res['history']
response.append((query, answer))
return response
接着,Gradio 界面通过这些函数搭建聊天机器人。Blocks API 用于搭建聊天机器人界面。发送信息(Send Message)按钮通过响应函数将请求发送至 ChatGPT。
import gradio as gr
with gr.Blocks() as demo:
session_id = gr.State(create_session_id)
with gr.Row():
with gr.Column(scale=2):
gr.Markdown('''## Chat''')
conversation = gr.Chatbot(label='conversation').style(height=300)
question = gr.Textbox(label='question', value=None)
send_btn = gr.Button('Send Message')
send_btn.click(
fn=respond,
inputs=[
session_id,
question
],
outputs=conversation,
)
demo.launch(server_name='127.0.0.1', server_port=8902)
界面如下所示:
至此,一个结合向量检索和 LLM 生成的智能聊天机器人就搭建完成啦!
05.总结
回顾一下,我们首先创建了 Towhee pipeline 来处理非结构化数据,并将其转化为向量并存储在 Milvus 向量数据库中。然后,搭建了一个查询 Pipeline,在聊天机器人中接入 LLM。最终,一个基础的聊天机器人界面便搭建完成。
简言之,Milvus 高度可扩展,提供高效的向量相似性搜索功能,能够帮助开发者轻松搭建聊天机器人、推荐系统、图片或文本识别等 ML 和 AI 应用。期待大家用 Milvus 搭建更出更棒的应用!
