AttributeError: module 'keras.optimizers' has no attribute 'Adam'

Use tf.keras.optimizers.Adam(learning_rate) instead of keras.optimizers.Adam(learning_rate)

As per the documentation , try to import keras into your code like this,

>>> from tensorflow import keras

This has helped me as well.

Make sure you've imported tensorflow:

import tensorflow as tf 

Then use

tf.optimizers.Adam(learning_rate)

There are ways to solve your problem as you are using keras 2.6 and tensorflow too:

• use (from keras.optimizer_v2.adam import Adam as Adam) but go through the function documentation once to specify your learning rate and beta values
• you can also use (Adam = keras.optimizers.Adam).
• (import tensorflow as tf) then (Adam = tf.keras.optimizers.Adam)

Use the form that is useful for the environment you set

I think you are using Keras directly. Instead of giving as from keras.distribute import —> give as from tensorflow.keras.distribute import

Hope this would help you.. It is working for me.
