等价的原因是因为 python calss 中的__call__和__init__方法. classA(): def__call__(self): print('i can be called like a function') a = A() a() out: i can be called like a function __call__里调用其他的函数 classA(): def__call__(self, param): print('i can called like ...
实际上module(data) 等价于module.forward(data) 等价的原因是因为 python calss 中的__call__ 可以让类像函数一样调用 当执行model(x)的时候,底层自动调用forward方法计算结果 class A(): def __call__(self): print('i can be called like a function') a = A() a() >>>i can be called like ...

Function的forward返回值 module的forward返回值 在module的call进行forward_hook操作,然后返回值 上述中“调用module的call方法”是指nn.Module 的__call__方法。定义__call__方法的类可以当作函数调用。也就是说,当把定义的网络模型model当作函数调用的时候就自动调用定义的网络模型的forward方法。nn.Module 的__call...
3. 继承于nn.autograd.function 要自己实现backward和forward函数,可能一些算法nn.functional中没有提供,要使用numpy或scipy中的方法实现。 这个要自己定义实现前向传播和反向传播的计算过程 几篇博客: https://oldpan.me/archives/pytorch-nn-module-functional-backward ...
等价的原因是python class中的call和init方法 classA():def__call__(self):print('i can be called like a function')a=A()a() out i can be called like a function 实例二 classA():def__call__(self,param):print('i can called like a function')print('传入参数的类型是:{} 值为: {}'...
Icancalledlikeafunction传入参数的类型是:<class'str'> 值为: dataforward函数被调用了inforward,传入参数类型是:<class'str'> 值为: data对象a传入的参数是:data 到这里我们就可以明白了为什么model(data)等价于model.forward(data),是因为__call__函数中调用了forward函数。[1] ...
print('i can be called like a function') a = A() a() 1. 2. 3. 4. 5. 6. 就会执行print函数,打印其中搞的文字。这里需要区别的是,实例化的时候,类的名称后面括号可以传递参数,例如前面实例化Fire的时候,传递in_channel,out_channel等参数。但是要利用__call__的特性,是在实例名后面的括号中传递...
