Cohere 教程:如何创建狗的品种识别 API

在当今世界,有许多来源可以获得有关动物的信息。然而,有时仅凭描述不足以确定动物的类型或品种。那么为什么不使用 Cohere AI 呢?

在本 Cohere 教程中,我们将尝试创建一个可用于根据简短描述确定狗品种的 API – 使用 Cohere API,然后使用 DALL·E 2 生成照片。

如果您想了解有关如何使用 Cohere AI 的更多信息,请查看我们的 Cohere 教程页面。

🏹 让我们开始吧


mkdir dog-breed-recognitioncd dog-breed-recognitionpython3 -m venv venv.envScriptsctivate

我们必须创建 Cohere 和 OpenAI 帐户,然后下载 API 密钥。我们将使用它们进行 API 授权。让我们创建.env文件并将它们放在那里:



pip install python-dotenvpip install --upgrade coherepip install openaipip install fastapi[all]


🤖 编码!


import osimport cohereimport openaifrom dotenv import load_dotenvfrom fastapi import FastAPI # load env. variablesload_dotenv()

然后我们需要创建一个 FastAPI 应用程序并授权 Cohere 和 OpenAI 客户端:

app = FastAPI() # initialize the Cohere Client with an API Keyco = cohere.Client(os.getenv('COHERE_API_KEY'))openai.api_key = os.getenv('OPENAI_API_KEY')

现在我将为 Cohere 的 LLM 定义一个提示。它将用于生成对狗品种的预测。我会将狗的品种及其描述的一些示例传递给模型。我会为我们的描述准备空间,这将被传递给模型。

def generate_prompt(description):    prompt = f'''Please predict the dog's breed in the description. Description: This dog is a medium-sized breed of dog that was developed in the United States. The breed is often used as a working dog on farms and ranches, and is also a popular companion animal.Breed: Australian Shepher--Description: This dog is a cheerful, high-spirited breed that is well suited for a variety of activities, including hunting, agility, and obedience. They are very intelligent and easily trained, and are excellent companions for active families.

Cockers have a reputation for being one of the most affectionate dog breeds, and are also known for being good with children.Breed: Cocker Spaniel--Description: {description}Breed:'''    return prompt

现在我们可以为我们的预测定义一个端点。我们将使用 Cohere 的 LLM 来生成预测。我们会将我们的提示传递给模型,然后我们将返回结果。然后结果将用于生成照片。

@app.get('/')def breed_prediction(description: str):    prompt = generate_prompt(description)    response = co.generate(        model='xlarge',        prompt=prompt,        max_tokens=5,        temperature=0.75,        stop_sequences=['--'],    )     breed = response.generations[0].text.strip()     img = openai.Image.create(        prompt=f'Image of {breed}',        n=1,        size='512x512'    )     img = img['data'][0]['url']      return {        'breed': breed,        'img': img    }

🚀 运行应用程序


uvicorn app:app --reload

我们可以通过向端点发送请求来测试我们的应用程序。为此,我将使用 Postman。它是测试 API 的绝佳工具。我们可以在这里下载。这就是我们的请求 URL 应该是这样的:



This is a large, white, fluffy dog with a thick coat. They are very friendly and love being around people. They were originally bred in Siberia to help people with their daily chores, such as pulling sleds and herding reindeer.
