核心代码

if t==1:
    X = numpy.array(xList)         #Unnormalized X's
    # X = numpy.array(xNormalized)   #Normlized Xss
    Y = numpy.array(labels)          #Unnormalized labels
    # Y = numpy.array(labelNormalized) #normalized lables
elif t==2:
    X = numpy.array(xList)           #Unnormalized X's
    X = numpy.array(xNormalized)     #Normlized Xss
    Y = numpy.array(labels)          #Unnormalized labels
    Y = numpy.array(labelNormalized) #normalized lables
elif t==3:
    X = numpy.array(xList)           #Unnormalized X's
    X = numpy.array(xNormalized)     #Normlized Xss
    Y = numpy.array(labels)          #Unnormalized labels
    # Y = numpy.array(labelNormalized) #normalized lables
