即使名称'net_input'在全局中也未定义

Question

我将net_input声明为全局变量，但仍然得到NameError: name 'net_input' is not defined

global net_input

noise = net_input.detach().clone()

错误行是：

net_input_saved = net_input.detach().clone()

错误

  

NameError：名称'net_input'未定义

Answer 1

首先，您需要定义变量，然后使其成为全局变量以在整个程序中使用。

net_input = "some object"   # assume this is an object and defined somewhere else in your program

global net_input            # make sure that net_input is defined prior 

noise = net_input.detach().clone()
