即使名稱'net_input'在全局中也未定義

Question

我將net_input聲明為全局變量，但仍然出現NameError: name 'net_input' is not defined

global net_input

noise = net_input.detach().clone()

錯誤行是：

net_input_saved = net_input.detach().clone()

錯誤

NameError：未定義名稱“ net_input”

Answer 1

首先，您需要定義變量，然后使其成為全局變量以在整個程序中使用。

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()
