自己的 Nominatim 服务器不能与 geopy 一起工作
own Nominatim server not working with geopy
我有一个包含超过 6k 个地址条目的数据库，需要进行地理编码，因此我安装了带有 docker 的 nominatim 服务器用于地理编码工作。它在 'localhost:8080' 上的 Web 表单中正常工作。
但是，当我尝试在 jupyter 中使用 geopy 进行查询时。它总是抛出错误。
我的 Jupyter 代码：
from geopy.geocoder import Nominatim
nom=Nominatim(domain='http://localhost:8080')
nom.geocode('some address') #the address works on the public server

感谢一些线索！
尝试从 url 中删除 http:// 并将其添加为 scheme 参数。在你的情况下
nom=Nominatim(domain='localhost:8080', scheme='http')
这是由于源代码中的以下部分
self.domain = domain.strip('/')
self.api = "%s://%s/search" % (self.scheme, self.domain)
其中 self.scheme 默认设置为 https
