Can't increase the number of layers

[IchigoKurosakii]

I am trying to increase the number of layers of the lstm_ctc.py but I get an error with the dimensions of the cell ( Dimensions must be equal , but are 1024 and 551).
I used different training data though than VCTK

Please check tensorflow's documentation for how to stack LSTM cell: https://www.tensorflow.org/api_docs/python/tf/nn/rnn_cell/MultiRNNCell
