使用基于嵌入的搜索来回答问题

GPT 在回答问题方面表现出色，但仅限于其训练数据中记忆的主题。

如果您想让 GPT 回答不熟悉的主题的问题，该怎么办？例如：

  • GPT 4 系列模型在 2023 年 10 月之后的近期事件
  • 您的非公开文档
  • 过去对话的信息
  • 等等

本笔记本演示了一个两步搜索-提问方法，用于使 GPT 能够使用参考文本库来回答问题。

  1. 搜索：搜索您的文本库以查找相关的文本部分
  2. 提问：将检索到的文本部分插入到给 GPT 的消息中，并向其提问

为什么搜索比微调更好

GPT 可以通过两种方式学习知识：

  • 通过模型权重（即，在训练集上微调模型）
  • 通过模型输入（即，将知识插入到输入消息中）

尽管微调可能感觉更自然——毕竟，通过数据进行训练是 GPT 学习其所有其他知识的方式——但我们通常不建议将其作为获取知识的方式。微调更适合教授专门的任务或风格，而对于事实回忆则不太可靠。

作为类比，模型权重就像长期记忆。当您微调模型时，就像在准备一周后的考试。考试到来时，模型可能会忘记细节，或者错误地回忆起它从未读过的事实。

相比之下，消息输入就像短期记忆。当您将知识插入消息时，就像带着开放的笔记参加考试。有了笔记在手，模型更有可能得出正确的答案。

与微调相比，文本搜索的一个缺点是，每个模型一次能读取的文本量是有限的：

| 模型 | 最大文本长度 |

模型 最大文本长度
gpt-4o-mini 128,000 tokens（约 384 页）
gpt-4o 128,000 tokens（约 384 页）

继续这个类比，您可以将模型想象成一个一次只能查看几页笔记的学生，尽管它可能拥有大量的教科书可供参考。

因此，要构建一个能够利用大量文本来回答问题的系统，我们建议使用搜索-提问方法。

搜索

文本可以通过多种方式进行搜索。例如：

  • 词汇搜索
  • 图搜索
  • 基于嵌入的搜索

本示例笔记本使用基于嵌入的搜索。嵌入易于实现，并且与问题特别有效，因为问题通常在词汇上不与其答案重叠。

将仅基于嵌入的搜索作为您自己系统的起点。更好的搜索系统可能会结合多种搜索方法，以及诸如流行度、时效性、用户历史记录、与先前搜索结果的冗余度、点击率数据等功能。通过诸如 HyDE 之类的技术，也可以提高问答检索性能，在这种技术中，问题首先被转换为假设的答案，然后再进行嵌入。同样，GPT 也可以通过自动将问题转换为关键字或搜索词集来改进搜索结果。

全过程

具体来说，本笔记本演示了以下过程：

  1. 准备搜索数据（每个文档一次）
    1. 收集：我们将下载几百篇关于 2022 年冬季奥运会的维基百科文章
    2. 分块：文档被分成简短的、大部分是自包含的部分，以便嵌入
    3. 嵌入：每个部分都使用 OpenAI API 进行嵌入
    4. 存储：嵌入被保存（对于大型数据集，请使用向量数据库）
  2. 搜索（每个查询一次）
    1. 给定用户问题，从 OpenAI API 生成查询的嵌入
    2. 使用嵌入，按与查询的相关性对文本部分进行排名
  3. 提问（每个查询一次）
    1. 将问题和最相关的文本部分插入到给 GPT 的消息中
    2. 返回 GPT 的答案

费用

由于 GPT 模型比嵌入搜索更昂贵，因此查询量适中的系统的成本将主要由第 3 步决定。

  • 对于 gpt-4o，考虑到每个查询约 1000 个 token，成本约为每查询 0.0025 美元，或每美元约 450 个查询（截至 2024 年 11 月）
  • 对于 gpt-4o-mini，每个查询使用约 1000 个 token，成本约为每查询 0.00015 美元，或每美元约 6000 个查询（截至 2024 年 11 月）

当然，确切的成本将取决于系统细节和使用模式。

序言

我们将首先：

  • 导入必要的库
  • 选择用于嵌入搜索和问答的模型
# imports
import ast  # 用于将保存为字符串的嵌入转换回数组
from openai import OpenAI # 用于调用 OpenAI API
import pandas as pd  # 用于存储文本和嵌入数据
import tiktoken  # 用于计算 token 数量
import os # 用于从环境变量 OPENAI_API_KEY 获取 API 密钥
from scipy import spatial  # 用于计算向量相似度以进行搜索

# 创建模型列表 
GPT_MODELS = ["gpt-4o", "gpt-4o-mini"]
# 模型
EMBEDDING_MODEL = "text-embedding-3-small"

client = OpenAI(api_key=os.environ.get("OPENAI_API_KEY", "<如果未设置为环境变量，则为您的 OpenAI API 密钥>"))

故障排除：安装库

如果您需要安装上述任何库，请在终端中运行 pip install {library_name}。

例如，要安装 openai 库，请运行：

pip install openai

（您也可以在笔记本单元格中使用 !pip install openai 或 %pip install openai 来完成此操作。）

安装后，请重新启动笔记本内核，以便加载库。

故障排除：设置您的 API 密钥

OpenAI 库将尝试从 OPENAI_API_KEY 环境变量读取您的 API 密钥。如果您还没有设置，可以按照这些说明来设置此环境变量。

激励示例：GPT 无法回答当前事件的问题

由于 gpt-4o-mini 的训练数据主要在 2023 年 10 月结束，因此模型无法回答有关近期事件的问题，例如 2024 年选举或最近的比赛。

例如，让我们尝试询问“有多少个？”：

# 关于 2022 年冬季奥运会的示例问题
query = 'Which athletes won the gold medal in curling at the 2022 Winter Olympics?'

response = client.chat.completions.create(
    messages=[
        {'role': 'system', 'content': 'You answer questions about the 2022 Winter Olympics.'},
        {'role': 'user', 'content': query},
    ],
    model=GPT_MODELS[0],
    temperature=0,
)

print(response.choices[0].message.content)

2022 年冬季奥运会男子冰壶比赛的金牌由瑞典选手 Niklas Edin、Oskar Eriksson、Rasmus Wranå、Christoffer Sundgren 和 Daniel Magnusson 获得。

女子冰壶比赛的金牌由英国选手 Eve Muirhead、Vicky Wright、Jennifer Dodds、Hailey Duff 和 Mili Smith 获得。

混合双人冰壶比赛的金牌由意大利选手 Stefania Constantini 和 Amos Mosaner 获得。

在 2024 年奥运会或最新事件方面，我没有信息。我的训练数据仅包含截至 2023 年 10 月的信息，而奥运会定于 2024 年 7 月 26 日至 8 月 11 日在巴黎举行。您可能需要查看可靠的体育新闻来源或官方奥运会网站以获取最新信息。

在 2024 年选举方面，我没有信息。有关 2024 年美国大选的最新信息，我建议您查阅可靠的新闻来源。

您可以通过将知识插入输入消息来为 GPT 提供有关某个主题的知识

为了帮助为模型提供关于 2022 年冬季奥运会花样滑冰的知识，我们可以将相关维基百科文章的前半部分复制并粘贴到我们的消息中：

wikipedia_article = """2024 Summer Olympics

The 2024 Summer Olympics (French: Les Jeux Olympiques d'été de 2024), officially the Games of the XXXIII Olympiad (French: Jeux de la XXXIIIe olympiade de l'ère moderne) and branded as Paris 2024, were an international multi-sport event held from 26 July to 11 August 2024 in France, with several events started from 24 July. Paris was the host city, with events (mainly football) held in 16 additional cities spread across metropolitan France, including the sailing centre in the second-largest city of France, Marseille, on the Mediterranean Sea, as well as one subsite for surfing in Tahiti, French Polynesia.[4]

Paris was awarded the Games at the 131st IOC Session in Lima, Peru, on 13 September 2017. After multiple withdrawals that left only Paris and Los Angeles in contention, the International Olympic Committee (IOC) approved a process to concurrently award the 2024 and 2028 Summer Olympics to the two remaining candidate cities; both bids were praised for their high technical plans and innovative ways to use a record-breaking number of existing and temporary facilities. Having previously hosted in 1900 and 1924, Paris became the second city ever to host the Summer Olympics three times (after London, which hosted the games in 1908, 1948, and 2012).[5][6] Paris 2024 marked the centenary of Paris 1924 and Chamonix 1924 (the first Winter Olympics), as well as the sixth Olympic Games hosted by France (three Summer Olympics and three Winter Olympics) and the first with this distinction since the 1992 Winter Games in Albertville. The Summer Games returned to the traditional four-year Olympiad cycle, after the 2020 edition was postponed to 2021 due to the COVID-19 pandemic.

Paris 2024 featured the debut of breaking as an Olympic sport,[7] and was the final Olympic Games held during the IOC presidency of Thomas Bach.[8] The 2024 Games were expected to cost €9 billion.[9][10][11] The opening ceremony was held outside of a stadium for the first time in modern Olympic history, as athletes were paraded by boat along the Seine. Paris 2024 was the first Olympics in history to reach full gender parity on the field of play, with equal numbers of male and female athletes.[12]

The United States topped the medal table for the fourth consecutive Summer Games and 19th time overall, with 40 gold and 126 total medals.[13] 
China tied with the United States on gold (40), but finished second due to having fewer silvers; the nation won 91 medals overall. 
This is the first time a gold medal tie among the two most successful nations has occurred in Summer Olympic history.[14] Japan finished third with 20 gold medals and sixth in the overall medal count. Australia finished fourth with 18 gold medals and fifth in the overall medal count. The host nation, France, finished fifth with 16 gold and 64 total medals, and fourth in the overall medal count. Dominica, Saint Lucia, Cape Verde and Albania won their first-ever Olympic medals, the former two both being gold, with Botswana and Guatemala also winning their first-ever gold medals. 
The Refugee Olympic Team also won their first-ever medal, a bronze in boxing. At the conclusion of the games, despite some controversies throughout relating to politics, logistics and conditions in the Olympic Village, the Games were considered a success by the press, Parisians and observers.[a] The Paris Olympics broke all-time records for ticket sales, with more than 9.5 million tickets sold (12.1 million including the Paralympic Games).[15]

Medals
Medals from the Games, with a piece of the Eiffel Tower
The President of the Paris 2024 Olympic Organizing Committee, Tony Estanguet, unveiled the Olympic and Paralympic medals for the Games in February 2024, which on the obverse featured embedded hexagon-shaped tokens of scrap iron that had been taken from the original construction of the Eiffel Tower, with the logo of the Games engraved into it.[41] Approximately 5,084 medals would be produced by the French mint Monnaie de Paris, and were designed by Chaumet, a luxury jewellery firm based in Paris.[42]

The reverse of the medals features Nike, the Greek goddess of victory, inside the Panathenaic Stadium which hosted the first modern Olympics in 1896. Parthenon and the Eiffel Tower can also be seen in the background on both sides of the medal.[43] Each medal weighs 455–529 g (16–19 oz), has a diameter of 85 mm (3.3 in) and is 9.2 mm (0.36 in) thick.[44] The gold medals are made with 98.8 percent silver and 1.13 percent gold, while the bronze medals are made up with copper, zinc, and tin.[45]


Opening ceremony
Main article: 2024 Summer Olympics opening ceremony

Pyrotechnics at the Pont d'Austerlitz marking the start of the Parade of Nations

The cauldron flying above the Tuileries Garden during the games. LEDs and aerosol produced the illusion of fire, while the Olympic flame itself was kept in a small lantern nearby
The opening ceremony began at 19:30 CEST (17:30 GMT) on 26 July 2024.[124] Directed by Thomas Jolly,[125][126][127] it was the first Summer Olympics opening ceremony to be held outside the traditional stadium setting (and the second ever after the 2018 Youth Olympic Games one, held at Plaza de la República in Buenos Aires); the parade of athletes was conducted as a boat parade along the Seine from Pont d'Austerlitz to Pont d'Iéna, and cultural segments took place at various landmarks along the route.[128] Jolly stated that the ceremony would highlight notable moments in the history of France, with an overall theme of love and "shared humanity".[128] The athletes then attended the official protocol at Jardins du Trocadéro, in front of the Eiffel Tower.[129] Approximately 326,000 tickets were sold for viewing locations along the Seine, 222,000 of which were distributed primarily to the Games' volunteers, youth and low-income families, among others.[130]

The ceremony featured music performances by American musician Lady Gaga,[131] French-Malian singer Aya Nakamura, heavy metal band Gojira and soprano Marina Viotti [fr],[132] Axelle Saint-Cirel (who sang the French national anthem "La Marseillaise" atop the Grand Palais),[133] rapper Rim'K,[134] Philippe Katerine (who portrayed the Greek god Dionysus), Juliette Armanet and Sofiane Pamart, and was closed by Canadian singer Céline Dion.[132] The Games were formally opened by president Emmanuel Macron.[135]

The Olympics and Paralympics cauldron was lit by Guadeloupean judoka Teddy Riner and sprinter Marie-José Pérec; it had a hot air balloon-inspired design topped by a 30-metre-tall (98 ft) helium sphere, and was allowed to float into the air above the Tuileries Garden at night. For the first time, the cauldron was not illuminated through combustion; the flames were simulated by an LED lighting system and aerosol water jets.[136]

Controversy ensued at the opening ceremony when a segment was interpreted by some as a parody of the Last Supper. The organisers apologised for any offence caused.[137] The Olympic World Library and fact-checkers would later debunk the interpretation that the segment was a parody of the Last Supper. The Olympic flag was also raised upside down.[138][139]

During the day of the opening ceremony, there were reports of a blackout in Paris, although this was later debunked.[140]

Closing ceremony


The ceremony and final fireworks
Main article: 2024 Summer Olympics closing ceremony
The closing ceremony was held at Stade de France on 11 August 2024, and thus marked the first time in any Olympic edition since Sarajevo 1984 that opening and closing ceremonies were held in different locations.[127] Titled "Records", the ceremony was themed around a dystopian future, where the Olympic Games have disappeared, and a group of aliens reinvent it. It featured more than a hundred performers, including acrobats, dancers and circus artists.[158] American actor Tom Cruise also appeared with American performers Red Hot Chili Peppers, Billie Eilish, Snoop Dogg, and H.E.R. during the LA28 Handover Celebration portion of the ceremony.[159][160] The Antwerp Ceremony, in which the Olympic flag was handed to Los Angeles, the host city of the 2028 Summer Olympics, was produced by Ben Winston and his studio Fulwell 73.[161]


Security
France reached an agreement with Europol and the UK Home Office to help strengthen security and "facilitate operational information exchange and international law enforcement cooperation" during the Games.[46] The agreement included a plan to deploy more drones and sea barriers to prevent small boats from crossing the Channel illegally.[47] The British Army would also provide support by deploying Starstreak surface-to-air missile units for air security.[48] To prepare for the Games, the Paris police held inspections and rehearsals in their bomb disposal unit, similar to their preparations for the 2023 Rugby World Cup at the Stade de France.[49]

As part of a visit to France by Qatari Emir Sheikh Tamim bin Hamad Al-Thani, several agreements were signed between the two nations to enhance security for the Olympics.[50] In preparation for the significant security demands and counterterrorism measures, Poland pledged to contribute security troops, including sniffer dog handlers, to support international efforts aimed at ensuring the safety of the Games.[51][52] The Qatari Minister of Interior and Commander of Lekhwiya (the Qatari security forces) convened a meeting on 3 April 2024 to discuss security operations ahead of the Olympics, with officials and security leaders in attendance, including Nasser Al-Khelaifi and Sheikh Jassim bin Mansour Al Thani.[53] A week before the opening ceremony, the Lekhwiya were reported to have been deployed in Paris on 16 July 2024.[54]

In the weeks running up to the opening of the Paris Olympics, it was reported that police officers would be deployed from Belgium,[55] Brazil,[56] Canada (through the RCMP/OPP/CPS/SQ),[57][58][59] Cyprus,[60] the Czech Republic,[61] Denmark,[62] Estonia,[63][64] Finland,[65] Germany (through Bundespolizei[66][67]/NRW Police[68]),[69] India,[70][71] Ireland,[72] Italy,[73] Luxembourg,[74] Morocco,[75] Netherlands,[76] Norway,[58] Poland,[77] Portugal,[78] Slovakia,[79] South Korea,[80][81] Spain (through the CNP/GC),[82] Sweden,[83] the UAE,[84] the UK,[49] and the US (through the LAPD,[85] LASD,[86] NYPD,[87] and the Fairfax County Police Department[88]), with more than 40 countries providing police assistance to their French counterparts.[89][90]

Security concerns impacted the plans that had been announced for the opening ceremony, which was to take place as a public event along the Seine; the expected attendance was reduced by half from an estimated 600,000 to 300,000, with plans for free viewing locations now being by invitation only. In April 2024, after Islamic State claimed responsibility for the Crocus City Hall attack in March, and made several threats against the UEFA Champions League quarter-finals, French president Emmanuel Macron indicated that the opening ceremony could be scaled back or re-located if necessary.[91][92][93] French authorities had placed roughly 75,000 police and military officials on the streets of Paris in the lead-up to the Games.[94]

Following the end of the Games, the national counterterrorism prosecutor, Olivier Christen, revealed that French authorities foiled three terror plots meant to attack the Olympic and Paralympic Games, resulting in the arrest of five suspects.[95]

Of course, this example partly relied on human intelligence. We knew the question was about summer olympics, so we inserted a Wikipedia article about 2024 paris olympics game.

The rest of this notebook shows how to automate this knowledge insertion with embeddings-based search.

1. Prepare search data

To save you the time & expense, we've prepared a pre-embedded dataset of a few hundred Wikipedia articles about the 2022 Winter Olympics.

To see how we constructed this dataset, or to modify it yourself, see Embedding Wikipedia articles for search.

3. 提问

有了上面的搜索函数，我们现在可以自动检索相关知识并将其插入到 GPT 的消息中。

下面，我们定义一个 ask 函数，该函数：

  • 接受用户查询
  • 搜索与查询相关的文本
  • 将该文本塞入给 GPT 的消息中
  • 将消息发送给 GPT
  • 返回 GPT 的答案
def num_tokens(text: str, model: str = GPT_MODELS[0]) -> int:
    """返回字符串中的 token 数量。"""
    encoding = tiktoken.encoding_for_model(model)
    return len(encoding.encode(text))


def query_message(
    query: str,
    df: pd.DataFrame,
    model: str,
    token_budget: int
) -> str:
    """返回给 GPT 的消息，其中包含从 DataFrame 中提取的相关源文本。"""
    strings, relatednesses = strings_ranked_by_relatedness(query, df)
    introduction = 'Use the below articles on the 2022 Winter Olympics to answer the subsequent question. If the answer cannot be found in the articles, write "I could not find an answer."'
    question = f"\n\nQuestion: {query}"
    message = introduction
    for string in strings:
        next_article = f'\n\nWikipedia article section:\n"""\n{string}\n"""'
        if (
            num_tokens(message + next_article + question, model=model)
            > token_budget
        ):
            break
        else:
            message += next_article
    return message + question


def ask(
    query: str,
    df: pd.DataFrame = df,
    model: str = GPT_MODELS[0],
    token_budget: int = 4096 - 500,
    print_message: bool = False,
) -> str:
    """使用 GPT 和包含相关文本和嵌入的 DataFrame 回答查询。"""
    message = query_message(query, df, model=model, token_budget=token_budget)
    if print_message:
        print(message)
    messages = [
        {"role": "system", "content": "You answer questions about the 2022 Winter Olympics."},
        {"role": "user", "content": message},
    ]
    response = client.chat.completions.create(
        model=model,
        messages=messages,
        temperature=0
    )
    response_message = response.choices[0].message.content
    return response_message

示例问题

最后，让我们向我们的系统提出关于金牌花样滑冰运动员的原始问题：

ask('Which athletes won the gold medal in curling at the 2022 Winter Olympics?')

"2022 年冬季奥运会冰壶比赛的金牌由以下运动员获得：\n\n- 男子比赛：瑞典的 Niklas Edin、Oskar Eriksson、Rasmus Wranå、Christoffer Sundgren 和 Daniel Magnusson。\n- 女子比赛：英国的 Eve Muirhead、Vicky Wright、Jennifer Dodds、Hailey Duff 和 Mili Smith。\n- 混合双人比赛：意大利的 Stefania Constantini 和 Amos Mosaner。"

使用最新的模型和嵌入搜索，我们的搜索系统能够为模型检索相关文本以供阅读，从而使其能够正确列出男子和女子比赛的金牌得主。

故障排除错误答案

如果我们发现任何错误，我们可以查看 GPT 获得文本的情况（通过设置 print_message=True）来判断错误是由于缺乏相关源文本（即搜索步骤失败）还是推理能力不足（即提问步骤失败）。

在这种情况中，查看下面的文本，可以看出排名第一的文章确实包含了所有三项比赛的奖牌得主，但后续结果更侧重于男子和女子比赛，这可能会分散模型的注意力，使其无法给出更完整的答案。

# 设置 print_message=True 以查看 GPT 正在使用的源文本
ask('Which athletes won the gold medal in curling at the 2022 Winter Olympics?', print_message=True)

Use the below articles on the 2022 Winter Olympics to answer the subsequent question. If the answer cannot be found in the articles, write "I could not find an answer."

"COVID-19 对 2022 年冬季奥运会产生了重大影响，主要体现在以下几个方面：\n\n1. **资格赛变更**：由于 2020 年比赛取消，疫情导致了冰壶和女子冰球等项目的资格赛发生变化。冰壶比赛的资格是根据 2021 年世界冰壶锦标赛的排名和奥运资格赛的结果来确定的，而国际冰球联合会则根据女子冰球的现有世界排名来确定资格。\n\n2. **生物安全协议**：国际奥委会宣布了严格的生物安全协议，要求所有运动员都必须待在生物安全气泡内，每天接受 COVID-19 检测，并且只能在比赛场馆之间往返。未完全接种疫苗或未获得有效医疗豁免的运动员必须隔离 21 天才能入境。\n\n3. **观众限制**：最初，只有中华人民共和国的居民被允许作为观众入场。后来，取消了向公众售票，并且只允许少量受邀观众入场，这使得连续第二届奥运会对公众关闭。\n\n4. **NHL 退赛**：国家冰球联盟 (NHL) 因 COVID-19 担忧以及需要补赛而退出了男子冰球比赛。\n\n5. **隔离和检测**：参加奥运会的所有人员都必须使用 My2022 移动应用程序进行健康报告和 COVID-19 检测记录。对该应用程序安全性的担忧导致一些代表团建议运动员使用一次性手机和笔记本电脑。\n\n6. **运动员缺席**：一些被认为是奖牌竞争者的顶尖运动员，在检测呈 COVID-19 阳性后（即使是无症状的）也无法前往中国。这包括像奥地利跳台滑雪运动员 Marita Kramer 和俄罗斯钢架雪车运动员 Nikita Tregubov。\n\n7. **投诉和争议**：运动员和团队官员对隔离条件表示不满，包括食物、设施和缺乏训练设备等方面的问题。一些运动员对检测流程和隔离管理表示沮丧。\n\n8. **COVID-19 病例**：奥运会期间共报告了 437 例 COVID-19 病例，其中防护气泡内的居民有 171 例，机场检测发现 266 例。尽管采取了严格的控制措施，但病例数量仅略低于 2020 年东京夏季奥运会报告的病例数。\n\n总的来说，COVID-19 对 2022 年冬季奥运会的组织、参与和体验产生了重大影响。"
