predict error for kmeans

[BeHappyForMe]

`from pyclustering.cluster.kmeans import kmeans, kmeans_visualizer from pyclustering.cluster.center_initializer import kmeans_plusplus_initializer from pyclustering.samples.definitions import FCPS_SAMPLES from pyclustering.utils import read_sample samples = read_sample(FCPS_SAMPLES.SAMPLE_TWO_DIAMONDS) initial_centers = kmeans_plusplus_initializer(samples, 2).initialize() kmeans_instance = kmeans(samples, initial_centers) kmeans_instance.process() clusters = kmeans_instance.get_clusters() final_centers = kmeans_instance.get_centers()

kmeans_instance.predict(samples)`

and i meet this:

---
