在循环中使用时，Namingm给出错误“101网络不可访问”和“GeocoderUnavailable:服务不可用”

Question

我正在IBM watson studio中使用jupitor笔记本电脑。 当我对一个地方使用Namingm时，我会像往常一样得到答案，但我有200多个地方的数据库，我想找到这些地方的位置。因此，当我对所有值进行循环时，就会出现上述错误。我已经导入了所有必要的库。 这是准确的密码

for address in amdavad:
       address = '{}, Ahmedabad'.format(amdavad["Borough"])
       geolocator = Nominatim(user_agent="foursquare_agent")
       location = geolocator.geocode(address)
       amdavad['Latitude'] = location.latitude
       amdavad['Longitude'] = location.longitude

这正是我得到的错误
