WebCreate a Numpy Array from a list with different data type. We can also pass the dtype as parameter in numpy.array(). In that case numpy.array() will not deduce the data type from passed elements, it convert them to passed data type. For example pass the dtype as float with list of int i.e. Web以下是iris数据集的一个示例: from sklearn.cluster import KMeans from sklearn import datasets import numpy as np centers = [[1, 1], [-1, -1], [1, -1]] iris = datasets.load_iris() X = iris.data y = iris.target km = KMeans(n_clusters=3) km.fit(X) 定义一个函数来提取您提供的集 …
