我找了所有“’Tensor’对象没有属性***”但似乎没有一个与Keras相关(除了

TensorFlow: AttributeError: ‘Tensor’ object has no attribute ‘log10’没有帮助)…

我正在制作一种GAN(Generative Adversarial Networks).在这里你可以找到结构.

Layer (type) Output Shape Param # Connected to

_____________________________________________________________________________

input_1 (InputLayer) (None, 30, 91) 0

_____________________________________________________________________________

model_1 (Model) (None, 30, 1) 12558 input_1[0][0]

_____________________________________________________________________________

model_2 (Model) (None, 30, 91) 99889 input_1[0][0]

model_1[1][0]

_____________________________________________________________________________

model_3 (Model) (None, 1) 456637 model_2[1][0]

_____________________________________________________________________________

我预先训练了model_2和model_3.事情是我预先训练了model_2,列表由0和1组成,但是model_1返回了接近的值.所以我考虑使用以下代码舍入model1_output：model1_out上的K.round().

import keras.backend as K

[...]

def make_gan(GAN_in, model1, model2, model3):

model1_out = model1(GAN_in)

model2_out = model2([GAN_in, K.round(model1_out)])

GAN_out = model3(model2_out)

GAN = Model(GAN_in, GAN_out)

GAN.compile(loss=loss, optimizer=model1.optimizer, metrics=['binary_accuracy'])

return GAN

[...]

我有以下错误：

AttributeError: ‘Tensor’ object has no attribute ‘_keras_history’

完全追溯：

Traceback (most recent call last):

我在Windows 7上使用Python 3.6和Spyder 3.1.4.我上周用pip升级了TensorFlow和Keras.

感谢您提供的任何帮助！
