问题描述
我正在尝试查找地址数据集的纬度和经度坐标。我目前正在尝试使用 Geopy 和 Nominatim 对我的数据进行地理编码，但我收到了一些无法解决的错误消息。请注意，这只是我用来测试此代码是否真的可以工作的虚拟地址。尽管我拥有的数据量很少，但我仍然收到了一段时间的错误消息，并且还收到了一个我不确定如何修复的 SSL 错误。首先，我已经包含了我的代码，并且还包含了我在它下面遇到的错误。
以下是我使用的代码：
!pip install geopy
import geopy
from geopy.geocoders import Nominatim
from geopy.extra.rate_limiter import RateLimiter
from geopy import distance
import pandas as pd
df = pd.read_csv(r"C:\Users\607868\Downloads\data.csv",#file name
sep=',') #seperator
df['address'] = df['COMPANY'] + " " + df['CITY'] + " " + df['COUNTRY']
df.drop_duplicates(subset ='address',keep ='first',inplace = True)
print("data row x columns is {}\ndata row count is {}".format(df.shape,len(df.index)))
df['location_lat'] = ""
df['location_long'] = ""
df['location_address'] = ""
geolocator = Nominatim(user_agent="Persephone032197An!")
location = geolocator.geocode(df.address)
这是我收到的错误。任何帮助，将不胜感激！我在我的智慧尽头：
