Marking this as ready to review as #480 is now merged.

@LukeWood this needs to have the GSoC2022 label.

[AdityaKane2001]

@sayakpaul @LukeWood

I have made the changes, please review again.

[sayakpaul]

LGTM given the linting tests pass!

[LukeWood]

Minor changes, thanks!

@LukeWood I have a workaround for the failing tests:

def custom_compare(obj1, obj2):
    if isinstance(obj1, (core.FactorSampler, tf.keras.layers.Layer)):
        return config_equals(obj1.get_config(), obj2.get_config())
    elif inspect.isfunction(obj1):
        return tf.keras.activations.serialize(obj1) == obj2
    elif inspect.isfunction(obj2):
        return obj1 == tf.keras.activations.serialize(obj2)
    else:
        return obj1 == obj2

The tests were failing when the passed object is a function. So, we check if it is a function and serialize it if it is. I'll replace activations.serialize by keras.utils.serialize_keras_object.

Awesome! Thanks for investigating this. Let’s update so the tests pass!

@LukeWood Done.

@sayakpaul @LukeWood

Even though this is a valid workaround at the moment, it would be interesting to see if there is any concrete solution to serializing and deserializing of functions. WDYT? Or is there some existing solution to this?

@sayakpaul @LukeWood

Could you please take a look at this one when you get a moment? TIA
