KeyError

[Marvin Schopf]

Hello,
When I'm executing predict.py using Keras' Theano backend, I always get an error like this:

Traceback (most recent call last):
  File "predict.py", line 134, in <module>
    generate()
  File "predict.py", line 25, in generate
    prediction_output = generate_notes(model, network_input, pitchnames, n_vocab)
  File "predict.py", line 92, in generate_notes
    result = int_to_note[index]
KeyError: 68 [or something similar, a.e. 143 or something else]

I switched to the theano backend, because TensorFlow gave me an error while installing.

I hope you can help me.

Hi,
I have not used the Theano backend with the program before so I'm not sure what is causing the error.

However, I would recommend trying to get Tensorflow to work since Theano is no longer being supported by the developers.
