error with the demo

[duernaT]

Hi! I tried to follow the example with [demo_01_segment_patches.ipynb] but I'm getting a problem:
on Run all batches section:

confscores = np.zeros((len(hsn.input_files_all), len(hsn.hn.class_names)))
...
...

RuntimeError: Attempted to aggregate unsupported object Tensor("sequential_1/activation_8/Sigmoid:0", shape=(16, 51), dtype=float32).

Any way to solve this error?

Best,
Duerna

after install
keras ==2.2.4
tensorflow ==1.13.1
the demo works well.
