OpenCV Error: Assertion failed (data0.dims <= 2 && type == CV_32F && K > 0) in cv::kmeans, file C:\projects\opencv-python\opencv\modules\core\src\kmeans.cpp, line 232
Traceback (most recent call last):
File "C:/Users/Administrator/PycharmProjects/sample/jiaozheng/bianyuan/cut_test.py", line 212, in <module>
ompactness, labels, centers = cv2.kmeans(lines, 4,None,criteria, 8, cv2.KMEANS_RANDOM_CENTERS)
cv2.error: C:\projects\opencv-python\opencv\modules\core\src\kmeans.cpp:232: error: (-215) data0.dims <= 2 && type == CV_32F && K > 0 in function cv::kmeans
原因：kmeans需要数据的float32类型，
解决：数据强转一下float32类型：
