错误(429)在Python中使用geopy进行地理编码时，请求过多 [英] error (429) Too Many Requests while geocoding with geopy in Python

问题描述

我有一个约有2万行的Pandas数据帧，我正在尝试按地址列将其地理编码为经纬度坐标.

I have a Pandas dataframe with ~20k rows, and I am trying to geocode by address column into lat/long coordinates.

我如何使用time.sleep()或其他功能来阻止我现在得到的Too Many Requests 429 error的OSM Nominatim?

How do I use time.sleep() or maybe other function to stop OSM Nominatim from Too Many Requests 429 error that I am getting now?

这是我用于此的代码:

from geopy.geocoders import Nominatim
from geopy.distance import vincenty

geolocator = Nominatim()
df['coord'] = df['address'].apply(geolocator.geocode).apply(lambda x: (x.latitude, x.longitude))
df.head()

提前谢谢！

推荐答案

geopy，因为1.16.0包含一个RateLimiter类，该类通过在查询之间添加延迟并重试失败的方法提供了一种方便的方式来处理Too Many Requests 429 error请求.

geopy since 1.16.0 includes a RateLimiter class which provides a convenient way to deal with the Too Many Requests 429 error by adding delays between the queries and retrying the failed requests.

from geopy.geocoders import Nominatim
geolocator = Nominatim(user_agent="specify_your_app_name_here")

from geopy.extra.rate_limiter import RateLimiter
geocode = RateLimiter(geolocator.geocode, min_delay_seconds=1)

df['coord'] = df['address'].apply(geocode).apply(lambda location: (location.latitude, location.longitude))
df.head()
