Pytorch学习笔记07----nn.Module类与前向传播函数forward的理解
Web我是 pytorch 的新手，只是尝试编写一个网络。是data.shape(204,6170)，最后 5 列是一些标签。数据中的数字是浮点数，如 0.030822。 protein food chart list
pytorch中forward(self, x)可否改为forward(self, x1, x2)？
Web来看一下nn.Sequential ()以及nn.ModuleList ()的主要区别，我个人感觉就是nn.Sequential ()里面自带了forward函数，可以直接操作输入，而nn.ModuleList ()需要定义一个forward函数 tt = [nn.Linear(10,10), nn.Linear(10,2)] n_1 = nn.Sequential(*tt) n_2 = nn.ModuleList(tt) x = torch.rand( [1,10,10]) x = Variable(x) n_1(x) n_2(x)#会出现NotImplementedError WebAug 30, 2024 · In this example network from pyTorch tutorial. import torch import torch.nn as nn import torch.nn.functional as F class Net(nn.Module): def __init__(self): super(Net, self).__init__() # 1 input image channel, 6 output channels, 3x3 square convolution # kernel self.conv1 = nn.Conv2d(1, 6, 3) self.conv2 = nn.Conv2d(6, 16, 3) # an affine operation: y = … WebLinear ( H, D_out) def forward( self, x): """ In the forward function we accept a Tensor of input data and we must return a Tensor of output data.
