I looked for all the “‘Tensor’ object has no attribute ***” but none seems related to Keras (except for TensorFlow: AttributeError: ‘Tensor’ object has no attribute ‘log10’ which didn’t help)…
I am making a sort of GAN (Generative Adversarial Networks). Here you can find the structure.
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] _____________________________________________________________________________
I pretrained model_2, and model_3. The thing is I pretrained model_2 with list made of 0 and 1, but model_1 return approached values. So i considered rounding the model1_output, with the following code : the K.round() on model1_out.
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 [...]
I have the following error :
AttributeError: ‘Tensor’ object has no attribute ‘_keras_history’

I’m using Python 3.6, with Spyder 3.1.4, on Windows 7. I upgraded TensorFlow and Keras with pip last week. Thank you for any help provided !
