python - 属性错误: 'module' object has no attribute 'm1'

Question

(cv) pi@raspberrypi:~/Desktop $ python pntc6.py
Traceback (most recent call last):
File "pntc6.py", line 24, in <module>
knn = cv2.m1.KNearest_create()
AttributeError: 'module' object has no attribute 'm1'

我正在尝试按照教程 http://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_ml/py_knn/py_knn_opencv/py_knn_opencv.html 进行操作并遇到了这个问题OpenCV 3.0.0-beta missing KNN? 我试图更换 KNearest与 cv2.ml和cv2.ml但我得到的只是 AttributeError: 'module' object has no attribute 'm1'

(我正在使用树莓派并按照本教程安装 open cv http://www.pyimagesearch.com/2015/10/26/how-to-install-opencv-3-on-raspbian-jessie/ 随后我 pip 安装了 matplotlib)

Answer 1

I tried to replace KNearest with cv2.ml and cv2.ml but all i get is AttributeError: 'module' object has no attribute 'm1'

knn = cv2.m1.KNearest_create()
           ^
           |__ this needs to be ml, not m1

但是您的代码建议您输入 m1(M 和数字 1)，而不是 ml(字母 M 和 L，如机器学习中的字母)
