Hi, I am trying to make a REST api on python where i put some AI models to predict, so i have to load the using tensorflow. I want to add some workers, so that i can call the server multiple times asynchronously. I run the script and i g...

faces 是定义在detectObject函数的局部变量，函数外不能访问。类似：def test(): a = [1,2,3,4]print a执行上面的代码，a就是undefined的。
