How to shape one-hot data for keras lstm
$begingroup$
I am trying to learn how to make an LSTM in keras and I was having difficulty working out what input dimensions the data needs to be for the cudnnlstm layer. Each time I try to alter the input_shape I get an error about expecting 2 dimensions and getting 3. My code is:
from keras.models import Sequential
from keras.layers import CuDNNLSTM,Dense,Dropout
import keras
x = [np.random.randint(0,10000) for i in range(5000)]
x = keras.utils.to_categorical(x)
y = np.roll(x,-1)
classes = x.shape[1]
model = Sequential()
model.add(CuDNNLSTM(256,batch_size=50,input_shape=(5000,classes),return_sequences=True))
model.add(Dropout(0.2))
model.add(CuDNNLSTM(256))
model.add(Dropout(0.2))
model.add(Dense(256,activation='relu'))
model.add(Dropout(0.2))
model.add(Dense(Z-hidden_size,activation='softmax'))
opt = keras.optimizers.Adam(lr=1e-3,decay=1e-5)
model.compile(loss='sparse_categorical_crossentropy',optimizer=opt)
model.fit(x,y,epochs=3)
python keras lstm
