import numpy as np#参数意思分别 是从a 中以概率P，随机选择3个,p没有指定的时候相当于是一致的分布 a1=np

N=21>>>indices=np.random.choice(N,1,replace=False)>>>indices array([5])>>>indices=np.random.choice(N

二、np.random.choice import numpy as np a1=np.array([3,5,2.6,41.2,5.7])a2=np.random.choice(a=a1,size

a=np.random.choice(a=5,size=3,replace=False,p=None)print(a)#非一致的分布，会以多少的概率提出来，出现

numpy.random.choice(a,size=None,replace=True,p=None)参数:a：一维数组如果是单个变量，则采用np.arange

np.random.choice(5,3) array([4,1,4]) np.random.choice(5,3,replace=False)#当replace为False时，生成的

np.random.choice(5,3,p=[0.1,0,0.3,0.6,0])array([3,3,0]) 从 np.arange(5)产生一个标准分布、size为 3、

numpy.random.choice numpy.random.choice(a,size=None,replace=True,p=None)Generates a random sample

np.random.choice(5,3)array([0,3,4])>>>np.random.choice(5,3,p=[0.1,0,0.3,0.6,0])array([3,3,0])>>>np.
