mobilenet模型

本文主要是介绍mobilenet模型，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

路径问题

os.path.join()

os.path.join() 函数：连接两个或更多的路径名组件

​ 1.如果各组件名首字母不包含’/’，则函数会自动加上

2.如果有一个组件是一个绝对路径，则在它之前的所有组件均会被舍弃

3.如果最后一个组件为空，则生成的路径以一个’/’分隔符结尾

Demo1

import osPath1 = 'home'
Path2 = 'develop'
Path3 = 'code'Path10 = Path1 + Path2 + Path3
Path20 = os.path.join(Path1,Path2,Path3)
print ('Path10 = ',Path10)
print ('Path20 = ',Path20)

输出

Path10 = homedevelopcode
Path20 = home\develop\code
