python - 名称 'net_input' 未定义，即使它在全局中

Question

我将 net_input 声明为全局变量，但仍然收到 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: name 'net_input' is not defined

Answer 1

首先您需要定义变量，然后将其设置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()
