即使名称'net_input'在全局中也未定义

Question

I declared net_input as a global variable but still I am getting NameError: name 'net_input' is not defined

global net_input

noise = net_input.detach().clone()

Error line is:

net_input_saved = net_input.detach().clone()

Error

NameError: name 'net_input' is not defined

Answer 1

First you need to define variable and then make it global to use in entire program.

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()
