TypeError: int returned non-int (type NoneType)

See original GitHub issue

After installing all requirements (python-midi and requirements.txt) I get this error message when executing generate.py:

Using TensorFlow backend.
Traceback (most recent call last):
  File "generate.py", line 153, in <module>
    main()
  File "generate.py", line 142, in main
    models = build_or_load()
  File "/Users/frederikriedel/Developer/DeepJ/util.py", line 15, in build_or_load
    models = build_models()
  File "/Users/frederikriedel/Developer/DeepJ/model.py", line 149, in build_models
    notes_out = naxis(time_out, chosen, style)
  File "/Users/frederikriedel/Developer/DeepJ/model.py", line 111, in f
    dense_layer_cache[l] = Dense(int(x.get_shape()[3]))
TypeError: __int__ returned non-int (type NoneType)

Do you maybe know what I’m missing here?

@calclavia @slave2sync @swarna-a-26 I am on Ubtuntu Linux with TF 1.12 with GPU (without GPU) and Keras 2.0. I am getting the same ValueError: Error when checking model input: expected input_1 to have 4 dimensions, but got array with shape (0, 1)

Any help would be much appreciated?

@frogg @dannywu19910524 I used tensorflow1.6.0 and keras 2.0.0.That seems to remove the above error.Thanks so much. I am getting the below error when I try to train the data. volume_dense (Dense) multiple 129

Any idea about this error? I created a data folder and have three mid files there. Any thoughts to overcome this issue? Is this one also related to keras and tensorflow version? any thoughts will be helpful.I am using MAC 10.13.1
