Hello I am trying to replicate the code and everything is working fine with no error but when I try to run get_predictions function I get an empty predicted transcription any ideas what is happening? bellow is the output:

Layer (type) Output Shape Param #

the_input (InputLayer) (None, None, 13) 0

rnn (GRU) (None, None, 29) 3741

softmax (Activation) (None, None, 29) 0

Total params: 3,741
Trainable params: 3,741
Non-trainable params: 0

None

True transcription:
