python type error: data type = 17 is not supported

python 3.6.1 opencv3

flags=cv2.KMEANS_RANDOM_CENTERS
retval, bestLabels, codebook = cv2.kmeans (features, self.codebookSize, None, term_crit, iterMax, flags)
self.classifier.train(codebook, np.arry(range(self.codebookSize)))

codebook=cv2.kmeans (features, self.codebookSize, None, term_crit, itaMax, flags)
type error: data data type = 17 is not supported

I think the cv2.kmeans parameter is correct, but I would appreciate it if you could let me know how to avoid the error.

In OpenCV, data type=17 means CV_8SC3 type, which means that there are three channels of signed 8-bit char.

For the cv2.kmeans document allows matrix elements as arguments for this function to be either CV_32F or CV_32FC2.Therefore, this program requires that the variable features be of type to one of these. Use features.shape or features.dtype to determine the matrix and element types.
