pytorch TCN中的批标准化代码

在pytorch TCN中，批标准化可以通过torch.nn.BatchNorm1d()函数实现。具体实现代码如下：

class TemporalBlock(nn.Module):
    def __init__(self, n_inputs, n_outputs, kernel_size, stride, dilation, padding, dropout=0.2):
        super(TemporalBlock, self).__init__()
        self.conv1 = nn.Conv1d(n_inputs, n_outputs, kernel_size,
                               stride=stride, padding=padding, dilation=dilation)
        self.chomp1 = Chomp1d(padding)
        self.relu1 = nn.ReLU()
        self.dropout1 = nn.Dropout(dropout)

        self.conv2 = nn.Conv1d(n_outputs, n_outputs, kernel_size,
                               stride=stride, padding=padding, dilation=dilation)
        self.chomp2 = Chomp1d(padding)
        self.relu2 = nn.ReLU()
        self.dropout2 = nn.Dropout(dropout)

        self.net = nn.Sequential(self.conv1, self.chomp1, self.relu1, self.dropout1,
                                  self.conv2, self.chomp2, self.relu2, self.dropout2)
        self.downsample = nn.Conv1d(n_inputs, n_outputs, 1) if n_inputs != n_outputs else None
        self.relu = nn.ReLU()
        self.init_weights()

    def init_weights(self):
        self.conv1.weight.data.normal_(0, 0.01)
        self.conv2.weight.data.normal_(0, 0.01)
        if self.downsample is not None:
            self.downsample.weight.data.normal_(0, 0.01)

    def forward(self, x):
        out = self.net(x)
        res = x if self.downsample is None else self.downsample(x)
        return self.relu(out + res)

其中，nn.BatchNorm1d()函数用于实现批标准化，Chomp1d()函数用于实现卷积后的裁剪操作。
