This error was occured. “TypeError: Expected int64, got 1e-07 of type 'float' instead.” . How can I do?

Question

I have a problem. A type error was occured. But I cannot solve it. At first, I thought it was a type problem. But I noticed the problem is not simple. The reason is my poor skill. But I can't find the solution. So, please help me.

I changed my tensorflow and keras version.

keras : 2.2.4
tensorflow : 1.13.1

The code:

x = Dozat(21)(x) # custom Lambda layer

print('x : ', x, '\n\n\n')

network = Model([w, p], x)
q = network.layers[8].output
print(q)

network.summary()

network.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])

The summary:

Answer 1

Try to change your data type from int to float . Maybe that will solve the problem.
