我正在尝试在以下存储库中执行github代码：

https://github.com/shubham3121/music-generation-using-rnn 错误在于以下功能：

def generate():
    """ Generate a piano midi file """
    #load the notes used to train the model
    with open('data/notes','rb') as filepath:
        notes = pickle.load(filepath)

    # Get all pitch names
    pitchnames = sorted(set(item for item in notes))
    # Get all pitch names
    n_vocab = len(set(notes))

    print('Initiating music generation process.......')

    network_input = get_inputSequences(notes,pitchnames,n_vocab)
    model = create_network(normalized_input,n_vocab)
    print('Loading Model weights.....')
    model.load_weights('weights.best.music3.hdf5')
    print('Model Loaded')
    prediction_output = generate_notes(model,network_input,n_vocab)
    create_midi(prediction_output)

问题如下：

Initiating music generation process.......

---------------------------------------------------------------------------

NameError                                 Traceback (most recent call last)

     16     print('Loading Model weights.....')
     17     model.load_weights('weights.best.music3.hdf5')

NameError: name 'normalized_input' is not defined

由于代码不是我的，我不知道这个变量是什么，所以我可以修复它... 我给代码所有者发了电子邮件，但他没有回复。

谢谢
