您可以将您的图层放在 ModuleList 容器:

You can put your layers in a ModuleList container:

import torch
import torch.nn as nn
import torch.nn.functional as F

class Net(nn.Module):

    def __init__(self, input_dim, output_dim, hidden_dim):
        super(Net, self).__init__()
        self.input_dim = input_dim
        self.output_dim = output_dim
        self.hidden_dim = hidden_dim
        current_dim = input_dim
        self.layers = nn.ModuleList()
        for hdim in hidden_dim:
            self.layers.append(nn.Linear(current_dim, hdim))
            current_dim = hdim
        self.layers.append(nn.Linear(current_dim, output_dim))

    def forward(self, x):
        for layer in self.layers[:-1]:
            x = F.relu(layer(x))
        out = F.softmax(self.layers[-1](x))
        return out    

对层使用 pytorch Containers 非常重要，而不是只是一个简单的python 列表.请参阅此答案以了解原因.

It is very important to use pytorch Containers for the layers, and not just a simple python lists. Please see this answer to know why.
