pytorch实现lstm代码

可以的，以下是一个简单的PyTorch实现LSTM的代码：

import torch
import torch.nn as nn

class LSTM(nn.Module):

    def __init__(self, input_dim, hidden_dim, batch_size, num_layers):
        super(LSTM, self).__init__()

        self.hidden_dim = hidden_dim
        self.batch_size = batch_size
        self.num_layers = num_layers

        self.lstm = nn.LSTM(input_dim, hidden_dim, num_layers, batch_first=True)
        self.fc = nn.Linear(hidden_dim, 1)

    def init_hidden(self):
        return (torch.zeros(self.num_layers, self.batch_size, self.hidden_dim),
                torch.zeros(self.num_layers, self.batch_size, self.hidden_dim))

    def forward(self, x):
        self.hidden = self.init_hidden()

        out, self.hidden = self.lstm(x, self.hidden)

        out = out[:, -1, :]
        out = self.fc(out)

        return out

希望对你有帮助！
