I am running a jupyter notebook from an Anaconda Prompt (Anaconda 3), and I am trying to use tensorflow keras.

I am trying to run the import statement:

from tensorflow.keras.models import Sequential

I get the following error:

ImportError                               Traceback (most recent call last)

Try this way 

from keras.utils.generic_utils import get_custom_objects
from keras.layers import Activation
get_custom_objects().update({'swish': Activation(swish)})

swish function needs to be passed into activation class to actually build it.

And then you can do

model.add(Dense(64, activation = "swish"))

You can download swish activation from pypi. Try the following:

  1. pip install swish-activation
  2. import swish_package
  3. from swish_package import swish

This is an older question, but I ended up taking Dr. Snoopy's suggestion uninstalling and reinstalling TensorFlow which solved my issue.
