工作功能（参见代码Python Pandas 'apply' 返回系列；无法转换为 dataframe）已停止工作。唯一的区别是我将字符串连接传递给它。
# Get geocode, return LAT and LON
def locate(x):
geolocator = Nominatim()
print("'" + x + "'")
location = geolocator.geocode(x) # Get geocode
print(location)
lat = location.latitude
lon = location.longitude
try:
#Get geocode
location = geolocator.geocode(x, timeout=8, exactly_one=True)
lat = location.latitude
lon = location.longitude
except:
#didn't work for some reason that I really don't care about
lat = np.nan
lon = np.nan
print(lat,lon)
return pd.Series([lat, lon])
这有效
In[4] locate('MOSCOW 123098 RUSSIA')
'MOSCOW 123098 RUSSIA'
Москва, Центральный административный округ, Москва, ЦФО, Россия
Out[4]:
0 55.751633
1 37.618704
dtype: float64
但这不会：
df_addr[['LAT','LON']] = df_addr['COUNTRY'].apply(locate(df_addr['CITY'] + ' ' + \
df_addr['PROVINCE'] + ' ' + \
df_addr['STATE'] + ' ' + \
df_addr['ZIP_CODE'] + ' ' + \
df_addr['COUNTRY'])) # Geocode it!
我看到函数回显正确的输入字符串：
0 'INNSBRUCK AUSTRIA'
1 'BERN CH-3001 SWITZERLAND'
2 'INNSBRUCK AUSTRIA'
3 'MOSCOW 123098 RUSSIA'
4 'MOSCOW 123098 RUSSIA'
5 'FREDERICK MD 21702 USA'
删除 try/except 我得到以下 fugly 异常信息

.
99 'GLASGOW LANARK G20 9NB SCOTLAND'

我在我头上。更新了所有库，但问题没有改变。
