python – ‘module’对象没有属性’svc’

import pandas as pd
from sklearn import svm

### Read the CSV ###
df = pd.read_csv('C:/Users/anagha/Documents/Python Scripts/sampleData.csv')
df

from sklearn.cross_validation import train_test_split
train,test = train_test_split(df,train_size = 0.8)
train
test

x_column=['Userid','day_of_week','hour_of_day','minute_of_hour']
y_column = ['thermostat']

svc = svm.SVC()
model = svm.svc(kernel='linear',c=1,gamma=1)

我收到错误AttributeError：’module’对象没有属性’svc’.尝试了很多技术,但没有一个是有效的.我是python的新手,非常感谢他们的帮助
