I have same error (using Keras API)

input_ = Input(batch_shape=(None, 1, dim_in), name='main_input')
out = Bidirectional(CuDNNGRU(256, return_sequences=True), name='BLSTM-256')(input_)
out = Bidirectional(CuDNNGRU(128, return_sequences=True), name='BLSTM-128')(out)
out = Bidirectional(CuDNNGRU(64, return_sequences=True), name='BLSTM-64')(out)
out = Bidirectional(CuDNNGRU(1, return_sequences=True), name='BLSTM-1')(out)
out = TimeDistributed(Dense(dim_out, activation='linear',), name='main_out')(out)
m = Model(inputs=[input_], outputs=[out])

X_train = [1900, 1, 6]
Y_train = [1900, 1, 4]
