AttributeError: module 'tensorflow.python.keras' has no attribute 'abs'

Question

I am working on an image classification problem with multiple classes and I follow the siamese face recognition sample here . I have saved processed data in.npy format and I have used Lambda in the siamese model. It shows an error in <lambda> :

distance_euclid = Lambda( lambda tensors : K.abs( tensors[0] - tensors[1] ))( [output_x1 , output_x2] )

AttributeError: module 'tensorflow.python.keras' has no attribute 'abs'

Here are the package versions I'm using:

keras        2.3.1
python       3.6.10
tensorflow   2.1.0

Answer 1

abs should be imported from tf.keras.backend ( tf.keras.backend.abs ) seems you are importing tf.python.keras . In your import modify this tf.python.keras line to tf.keras.backend

In addition, don't forget to upgrade tensorflow :

pip install -U tensorflow
