'AdversarialModel' object has no attribute 'nodes_by_depth'

[sukhadj]

I tried using this module and got following error:
'AdversarialModel' object has no attribute 'nodes_by_depth'

The stack traceback is :

Traceback (most recent call last):
File "/home/sukhad/Workspace/PyCharm/GAN/main.py", line 66, in
print(model.summary())
File "/home/sukhad/env/lib/python3.5/site-packages/keras/engine/topology.py", line 2708, in summary
print_fn=print_fn)
File "/home/sukhad/env/lib/python3.5/site-packages/keras/utils/layer_utils.py", line 39, in print_summary
nodes_by_depth = model.nodes_by_depth.values()
AttributeError: 'AdversarialModel' object has no attribute 'nodes_by_depth'

Any idea about how to solve to this issue?
Thanks.
