Hi

My name is Wemerson and I'm trying to replicate your results.

When I start your code with your dataset I receive the following error:

What I´m doing wrong? ( I already tried to remove all ocorrences of only one question, but it doesn't work)

Thank You

you have to change line
from
overall_loss[0] += model.train_on_batch(X, Y)[0]
to
overall_loss[0] += model.train_on_batch(X, Y)

this could happen because of version change.

Thank You... I had already realized that! ;)
