#测试深度学习中的二分类返回的数据类型
import numpy as np

import random

from keras.utils import np_utils
x = np.arange(20).reshape((20,1))
fuc = []
for i in range(20):
if i/10>=1:

else:
fuc.append(5)
print(fuc)
X_data, X_test, y_train, y_test = train_test_split(x, fuc, test_size=0.3,random_state=random.randint(0, 100))
print(np.shape(y_train))
print(y_train)
Y_train = np_utils.to_categorical(y_train, num_classes=11)/255#num_classes表示有多少类。大于数字的总和也是可以的
print(y_train)
输出结果:
