Question

我正在尝试为电视脚本生成创建模型，并且在运行以下模型时，发生输入层和嵌入层错误。我试过在没有这两行的情况下运行模型，并且效果很好。有人可以帮我解决这个错误吗？

embedding = 300
lstm_size = 128
vocab_size = len(vocab) #8420
seq_len = 100


model = Sequential()
model.add(Input((None, )))
model.add(Embedding(inp, input_dim = vocab_size, output_dim = embedding, 
input_length = 1000))
model.add(LSTM(lstm_size, return_sequences = True, return_state = True))
model.add(LSTM(lstm_size, return_sequences = True, return_state = True))
model.add(LSTM(lstm_size, return_sequences = True, return_state = True))
model.add(Flatten())
model.add(Dense(vocab_size))

TypeError                                 Traceback (most recent call last)

 20 model = Sequential()
---> 21 model.add(Input((None, )))
 22 model.add(Embedding(inp, input_dim = vocab_size, output_dim = embedding, input_length = 1000))
 23 model.add(LSTM(lstm_size, return_sequences = True, return_state = True))

TypeError: The added layer must be an instance of class Layer. Found: Tensor("input_37:0", shape=(?, ?), dtype=float32)


This is coming for the Input layer
and,

 23 model.add(LSTM(lstm_size, return_sequences = True, return_state = True))
 24 model.add(LSTM(lstm_size, return_sequences = True, return_state = True))

TypeError: __init__() got multiple values for argument 'input_dim'

this comes for embedding layer.

Answer 1

输入不是图层对象。这就是为什么您会遇到第一个错误的原因。您无需通过调用Sequential（）传递类似的信息。 Embedding（）可以是您的第一层。

第二个错误是因为您要向其传递inp。第一个值应该是inp或vocab_size，但不能两者都是。

基本上

embedding = 300
lstm_size = 128
vocab_size = len(vocab) #8420
seq_len = 100


model = Sequential()
model.add(Embedding(vocab_size, embedding, input_length = 1000))
