lstm in encoder code example

Example: Encoder LSTM

class Encoder(nn.Module):
    def __init__(self, vocab_len, embedding_dim, hidden_dim, n_layers, dropout_prob):
        super().__init__()
 
        self.embedding = nn.Embedding(vocab_len, embedding_dim)
        self.rnn = nn.LSTM(embedding_dim, hidden_dim, n_layers, dropout=dropout_prob)
 
        self.dropout = nn.Dropout(dropout_prob)
 
    def forward(self, input_batch):
        embed = self.dropout(self.embedding(input_batch))
        outputs, (hidden, cell) = self.rnn(embed)
 
        return hidden, cell
