OpenCV属性错误：'module'对象没有属性'SVM_RBF'

Question

我刚开始在python中使用OpenCV 3.0。我正在尝试其中一个例子＆＃34; didgits.py＆＃34;我收到属性错误：

Traceback (most recent call last):
  File "C:\Users\Arpit Jindal\Desktop\opencv\sources\samples\python2\digits.py", line 171, in <module>
    model = KNearest(k=4)
  File "C:\Users\Arpit Jindal\Desktop\opencv\sources\samples\python2\digits.py", line 77, in __init__
    self.model = cv2.KNearest()
AttributeError: 'module' object has no attribute 'KNearest'

然后我评论了KNearest的代码并仅针对SVM进行了尝试，并且我再次收到了属性错误：

Traceback (most recent call last):
  File "C:\Users\Arpit Jindal\Desktop\opencv\sources\samples\python2\digits.py", line 177, in <module>
    model = SVM(C=2.67, gamma=5.383)
  File "C:\Users\Arpit Jindal\Desktop\opencv\sources\samples\python2\digits.py", line 89, in __init__
    self.params = dict( kernel_type = cv2.SVM_RBF,
AttributeError: 'module' object has no attribute 'SVM_RBF'

我试图在OpenCV中搜索这些变量，但无法找到任何内容。

python示例是否未更新？我在哪里可以找到完整的python API列表和OpenCV3.0 python的参考手册，因为在线docs还没有完成机器学习，因为我发现2.4.9中提到了很多python API但没有在3.0？
