好的,以下是一个简单的 PyTorch LSTM 模型代码:
``` python
import torch
import torch.nn as nn
class LSTMModel(nn.Module):
def __init__(self, input_size, hidden_size, num_layers, num_classes):
super(LSTMModel, self).__init__()
self.hidden_size = hidden_size
self.num_layers = num_layers
self.lstm = nn.LSTM(input_size, hidden_size, num_layers, batch_first=True)
self.fc = nn.Linear(hidden_size, num_classes)
def forward(self, x):
h0 = torch.zeros(self.num_layers, x.size(0), self.hidden_size).to(device)
c0 = torch.zeros(self.num_layers, x.size(0), self.hidden_size).to(device)
out, _ = self.lstm(x, (h0, c0))
out = self.fc(out[:, -1, :])
return out
```
希望能对您有所帮助。
