Describe the current behavior Cannot import keras.optimizers when done like this

from tensorflow.keras.optimizers import *

ImportError                               Traceback (most recent call last)

     10 from tensorflow.python.keras.applications.densenet import AveragePooling2D
     11 from tensorflow.python.keras.applications.densenet import AveragePooling2D as AvgPool2D

ImportError: cannot import name 'Activation'

but this seems to work fine

import tensorflow as tf
optim = tf.keras.optimizers.Adam()

what weird is that even this works

from tensorflow.python.keras.optimizers import *

I had the same problem, and i solved it by :

from tensorflow.keras.optimizers import RMSprop

instead of :

from keras.optimizers import RMSprop

@Piyushagg19 I had importes like: import tensorflow as tf from tensorflow import keras from keras…optimizers import Adam

then I done: from tensorflow.keras.optimizers import Adam

and it works for me

I think, it’s nessesary to add tensorflow before keras

As @LazyDareDevil mentioned: from tensorflow.keras.optimizers import works.

Then I was able to add: adam=Adam(learning_rate = 0.01) and model.compile(optimizer='adam', loss='sparse_categorical_crossentropy', metrics=['accuracy'])
