写一个transformer的代码

我可以分享一个关于 Transformer 的代码示例，你可以看一下：import torch
import torch.nn as nnclass Transformer(nn.Module):
def __init__(self, input_size, num_layers):
super(Transformer, self).__init__()
self.input_size = input_size
self.num_layers = num_layers
self.encoder_layer = nn.TransformerEncoderLayer(self.input_size, self.num_layers)
self.encoder = nn.TransformerEncoder(self.encoder_layer, num_layers)

def forward(self, x):
return self.encoder(x)
