        switch to tf.keras.optimizers or tf.compat.v1 canned Estimators.
    *   A checkpoint converter for canned Estimators has been provided to
        transition canned Estimators that are warm started from
        `tf.train.Optimizers` to `tf.keras.optimizers`.
    *   Losses are scaled in canned estimator v2 and not in the optimizers
