add seq2seq layer to embedding layer with mask raise "Exception: Layers should have equal number of output tensors and output masks. Layer recurrent_sequential_1 has 3 output tensors and 4 output masks."

[shelfee]

model = Sequential() model.add(Embedding(39, 39, input_length=24, mask_zero=True)) model.add(Seq2Seq(input_length=24, input_dim=39, hidden_dim=10, output_length=22, output_dim=39))
raise the Exception

I've the exact same Exception with an ultra simple:
base_model = Seq2Seq(input_dim=128, input_length=150, hidden_dim=512, output_length=150, output_dim=128, depth=2) multi_model = multi_gpu_model(base_model, gpus=2) multi_model.compile(loss='mse', optimizer='adam', metrics=['mse'])

I don't have any masks and with the AttentionSeq2Seq class just worked...

Same issue.

I encounter this problem too.

I encounter this problem too. just executed the example code;
tensorflow==1.13.1
keras==2.2.4
python==3.6.2
