python - 发生此错误。 "TypeError: Expected int64, got 1e-07 of type ' float' instead."。我该怎么办？

Question

我有一个问题。出现类型错误。但我无法解决它。起初，我认为这是一个类型问题。但我注意到问题并不简单。原因是我技术差。但我找不到解决方案。所以，请帮助我。

我更改了我的 tensorflow 和 keras 版本。

keras : 2.2.4
tensorflow : 1.13.1

代码:

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'])

Answer 1

尝试将数据类型从 int 更改为 float。也许这会解决问题。
