- readlines() Read the entire contents of the file on a line at a time , Put the read in a list , return list type .
txt Image name in file & Image name under the original directory file ：
train.txt： train_0.png, train_1.png, train_2.png, train_3.png, ……
label Folder （ original ）：0.png, 1.png, 2.png, 3.png, 4.png, 5.png,……（ Numerous ）
label2 Folder （ Generate ）：train_0.png, train_1.png, train_2.png, train_3.png, ……（ part ）
