Question about Tensorflow compatibility

[chenmoneygithub]

Hi team!

I have a few questions about the Tensorflow compatibility, could you help clarify?

1. In future Tensorflow versions (I assume it's starting from 2.16), will TF depend on Keras 3 instead of tf-keras?
2. If 1 is correct, does it mean tf-keras will be a frozen package?
3. Will from tensorflow import keras or tf.keras keep working? This is not the best practice, but MLflow (the package I am maintaining now) needs to keep the backward compatibility, so from tensorflow import keras will be the simplest solution.

Thanks for the help!

Best, Chen Money

from my experiences (i am porting over my models to keras 3)

1. tf works as is, i think the minimum required tf version is ~2.12
2. tf.keras and keras cannot be imported at the same time (meaning that your code should either do all tf.keras or all keras.)
3. you can still mix tf code in keras3 (eg. calling tf.boolean_mask or some other ops). only tf.keras need to be changed

@chenmoneygithub - Thanks for raising this issue.

1. Starting in TF 2.16, Keras 3 will be installed with TensorFlow. But TF will also remain compatible with tf-keras and users can switch via env. variable TF_USE_LEGACY_KERAS=1 and installing tf-keras pip package.

does it mean tf-keras will be a frozen package?

2. We will continue to release a tf-keras version that's aligned with TensorFlow version for users wanting to use Keras 2.

3. from tensorflow import keras will use Keras 3 from TF 2.16 unless the env variable is set, which will then import tf_keras package (keras 2).
