不废话，有需要使用的直接修改输入输出路径和修改后的图片尺寸大小（注释处）
from PIL import Image
from os import listdir
import numpy as np
def resize_img(input_path, out_path, x, y):
fp = open(input_path, 'rb')
pic = Image.open(fp)
pic_array = np.array(pic)
fp.close()
img = Image.fromarray(pic_array)
print("修改前: ", img.size)
new_img = img.resize((x, y))
new_img.save(out_path)
print("修改后: ", new_img.size)
if __name__ == '__main__':
inpath = "C:\UserszhgdaDesktop图片3" # 在此输入图片输入路径
outpath = "C:\UserszhgdaDesktop图片4" # 在此输入图片输出路径
x = 360 # 图片水平长度
y = 240 # 图片垂直长度
for i in listdir(inpath):
resize_img(inpath + '\' + i, outpath + '\' + i, x, y)
print("--------------------")
