天气

OpenWeatherMap 是一个开源天气服务提供商

这个 loader 使用 pyowm Python 包从 OpenWeatherMap 的 OneCall API 获取天气数据。您必须使用您的 OpenWeatherMap API 令牌和您想要天气数据的城市名称来初始化 loader。

from langchain_community.document_loaders import WeatherDataLoader
API Reference:WeatherDataLoader
%pip install --upgrade --quiet  pyowm
# Set API key either by passing it in to constructor directly
# or by setting the environment variable "OPENWEATHERMAP_API_KEY".

from getpass import getpass

OPENWEATHERMAP_API_KEY = getpass()
loader = WeatherDataLoader.from_params(
    ["chennai", "vellore"], openweathermap_api_key=OPENWEATHERMAP_API_KEY
)
documents = loader.load()
