快速使用

使用ERNIE Bot SDK之前,请首先申请并设置鉴权参数。具体请参考认证鉴权

Python接口

import erniebot

# List supported models
models = erniebot.Model.list()

print(models)
# ernie-bot             文心一言模型(ernie-bot)
# ernie-bot-turbo       文心一言模型(ernie-bot-turbo)
# ernie-bot-4           文心一言模型(ernie-bot-4)
# ernie-bot-8k          文心一言模型(ernie-bot-8k)

# ernie-vilg-v2         文心一格模型

# Set authentication params
erniebot.api_type = "aistudio"
erniebot.access_token = "<access-token-for-aistudio>"

# Create a chat completion
response = erniebot.ChatCompletion.create(model="ernie-bot", messages=[{"role": "user", "content": "你好,请介绍下你自己"}])

print(response.get_result())

命令行接口(CLI)

# List supported models
erniebot api model.list

# Set authentication params for chat_completion.create
export EB_API_TYPE="aistudio"
export EB_ACCESS_TOKEN="<access-token-for-aistudio>"

# Create a chat completion (using ernie-bot, ernie-bot-turbo, etc.)
erniebot api chat_completion.create --model ernie-bot --message user "请介绍下你自己"

# Set authentication params for image.create
export EB_API_TYPE="yinian"
export EB_ACCESS_TOKEN="<access-token-for-yinian>"

# Generate images via ERNIE-ViLG
erniebot api image.create --model ernie-vilg-v2 --prompt "画一只驴肉火烧" --height 1024 --width 1024 --image-num 1

典型示例

对话补全(Chat Completion)

ERNIE Bot SDK提供具备对话补全能力的ernie-bot、ernie-bot-turbo、ernie-bot-4、ernie-bot-8k等文心一言系列模型。

不同模型在效果、速度等方面各有千秋,大家可以根据实际场景的需求选择合适的模型。

以下是调用ernie-bot模型进行多轮对话的示例:

import erniebot

erniebot.api_type = "aistudio"
erniebot.access_token = "<access-token-for-aistudio>"

response = erniebot.ChatCompletion.create(
    model="ernie-bot",
    messages=[{
        "role": "user",
        "content": "请问你是谁?"
    }, {
        "role": "assistant",
        "content":
        "我是百度公司开发的人工智能语言模型,我的中文名是文心一言,英文名是ERNIE-Bot,可以协助您完成范围广泛的任务并提供有关各种主题的信息,比如回答问题,提供定义和解释及建议。如果您有任何问题,请随时向我提问。"
    }, {
        "role": "user",
        "content": "我在深圳,周末可以去哪里玩?"
    }])

print(response.get_result())

语义向量(Embedding)

ERNIE Bot SDK提供用于生成文本的向量表示的ernie-text-embedding模型。

该模型基于文心大模型,使用海量数据训练得到,为文心百中系统提供关键能力。该模型可以将输入文本转为384维浮点数表示的向量。这些向量具备精准的语义表达能力,可用于度量文本之间的语义相似度。

大家可以使用以下代码生成句子的向量表示:

import erniebot

erniebot.api_type = "aistudio"
erniebot.access_token = "<access-token-for-aistudio>"

response = erniebot.Embedding.create(
    model="ernie-text-embedding",
    input=[
        "我是百度公司开发的人工智能语言模型,我的中文名是文心一言,英文名是ERNIE-Bot,可以协助您完成范围广泛的任务并提供有关各种主题的信息,比如回答问题,提供定义和解释及建议。如果您有任何问题,请随时向我提问。",
        "2018年深圳市各区GDP"
        ])

print(response.get_result())

大家可以登陆文心百中体验中心,体验更多大模型语义搜索的能力。

文生图(Image Generation)

ERNIE Bot SDK提供具备文生图能力的ernie-vilg-v2大模型。

该模型具备丰富的风格与强大的中文理解能力,支持生成多种尺寸的图片。

import erniebot

erniebot.api_type = "yinian"
erniebot.access_token = "<access-token-for-yinian>"

response = erniebot.Image.create(
    model="ernie-vilg-v2",
    prompt="雨后的桃花,8k,辛烷值渲染",
    width=512,
    height=512
)

print(response.get_result())

我们推荐两个撰写文生图提示词的文档,大家可以组合使用,创作出更加精美的图片。

大家也可登陆文心一格平台,体验更多AI艺术与创意辅助的能力。

函数调用(Function Calling)

ERNIE Bot SDK提供函数调用功能,即由大模型根据对话上下文确定何时以及如何调用函数。

借由函数调用,用户可以从大模型获取结构化数据,进而利用编程手段将大模型与已有的内外部API结合以构建应用。

以下是调用ernie-bot模型进行函数调用的示例:

import erniebot

erniebot.api_type = "aistudio"
erniebot.access_token = "<access-token-for-aistudio>"

response = erniebot.ChatCompletion.create(
    model="ernie-bot",
    messages=[{
        "role": "user",
        "content": "深圳市今天气温多少摄氏度?",
    }, ],
    functions = [
        {
            "name": "get_current_temperature",
            "description": "获取指定城市的气温",
            "parameters": {

                            "华氏度",
                        ],
                    },
                },
                "required": [
                    "location",
                    "unit",
                ],
            },
            "responses": {
                "type": "object",
                "properties": {
                    "temperature": {
                        "type": "integer",
                        "description": "城市气温",
                    },
                    "unit": {
                        "type": "string",
                        "enum": [
                            "摄氏度",
                            "华氏度",
                        ],
                    },
                },
            },
        },
    ],
    stream=False)
print(response.get_result())
