用CSV读取时出现Geohash KeyError

Question

我正在尝试读取geohhes的CSV文件，并将其转换为经/纬度。我正在使用Python的Geohash模块。这是我的代码：

import Geohash
import csv
with open('C:\Users\Data\myData.csv') as csvfile:
    readCSV = csv.reader(csvfile, delimiter=',')
    for row in readCSV:
        geoHash = row[0]
        print(str(geoHash)) #This prints sucessfully
        geoStr = str(geoHash)
        Geohash.decode(geoStr) #This fails

该代码仅在最后一行失败，geoStr成功输出了每个geohash。我收到的错误是：

Traceback (most recent call last):

文件

"C:/Users/PycharmProjects/GeoHash/GeoHash_to_LatLong.py", line 11, in <module>
    Geohash.decode(geoStr)
  File "C:\Users\PycharmProjects\GeoHash\venv\lib\site-packages\Geohash\geohash.py", line 68, in decode
    lat, lon, lat_err, lon_err = decode_exactly(geohash)
  File "C:\Users\PycharmProjects\GeoHash\venv\lib\site-packages\Geohash\geohash.py", line 44, in decode_exactly
    cd = __decodemap[c]
KeyError: 'o'

我已经检查了CSV，似乎没有任何奇数字符或任何会导致失败的字符。有什么想法吗？
