pyecharts想导入数据地图

pyecharts想导入数据做地图

from _ctypes_test import func
from pyecharts.charts import Geo
#导入各省GDP数据
df = pd.read_csv(r"D:\data1py\地区生产总值2.csv", encoding='GBK')
print(df)
#将需要展示的数据转为二维列表格式，以便pyecharts使用
ls_2021 = df[['地区','2021年']].values.tolist()

geo = Geo()
geo.add_schema(maptype="china")
#加入数据
geo.add('图表名称：2021年各省GDP', ls_2021)
geo.render()

报错如下

Traceback (most recent call last):
  File "D:\pythonProject1\venv\Lib\site-packages\pyecharts\charts\basic_charts\geo.py", line 217, in _feed_data
    lng, lat = self.get_coordinate(n)
TypeError: cannot unpack non-iterable NoneType object

During handling of the above exception, another exception occurred:
