Keras and Tensorflow Versions

When I run the code I got this error on line 100 of transformer.py:

ValueError: Axis 0 of input tensor should have a defined dimension, but is None. Full tensor shape: (None, None, None). Typically you need to pass a fully-defined input_shape argument to your first layer.

could you specify the versions of keras and tensorflow that you used for your test?
