我在 Windows 中运行脚本，我收到以下错误：
Traceback (most recent call last):
File "C:\Users\esalazar\Desktop\datos\stat_cea_2011\emas\amealco\promedios-emas.py", line 64, in <module>
g=index.groupby(level=0)
AttributeError: 'NoneType' object has no attribute 'groupby'
我已经安装了 pandas、scipy 和 numpy。我需要安装其他库吗？如何修复此错误？
这是我的代码的一部分：
data = pd.read_csv('C:/Users/esalazar/Desktop/datos/stat_cea_2011/emas/amealco/enero.csv',skiprows=1,names=['Fecha','Hora','C','D','E','Temperatura','TempRocio','DirViento','I','MagViento','K','Humedad','Presion','N','PreciAcu','P','Q','R','S'],header=0)
Uviento=[]
Vviento=[]
for i in range(0,len(data['MagViento'])):
Uviento.append((data['MagViento'][i]*sin((data['DirViento'][i]+180)*(pi/180.0))))
Vviento.append((data['MagViento'][i]*cos((data['DirViento'][i]+180)*(pi/180.0))))
data['PromeU']=Uviento
data['PromeV']=Vviento
data

df = data.set_index(['Fecha','Hora'],inplace=True)
df
我得到这个错误
TypeError: NoneType object has no atribute '--getitem--'
所以，
grouped = df.groupby(level=0)
也是错误。
