The layer "sequential_1 has multiple inbound nodes, with different input shapes. Hence the notion of "input shape" is ill-defined for the layer. Use get_input_shape_at(node_index) instead.

Hi I seem to be running
$ python test_catch.py
and here is what I seem to get

Epoch 1000/1000 | Loss 0.0104 | Epsilon 0.10 | Win count 793

I have seen the same error

[gaara100]

I'm having the same issue.

Same. Looks like something changed in Keras?

[sdgroeve]

same here....

[vftens]

The same error.
Use
Keras==1.2.2
tensorflow==1.3.0
tensorflow-gpu==1.3.0
to avoid such error
