tf.keras.mixed_precision.global_policy

Returns the global dtype policy.

The global policy is the default tf.keras.mixed_precision.Policy used for layers, if no policy is passed to the layer constructor. If no policy has been set with keras.mixed_precision.set_global_policy, this will return a policy constructed from tf.keras.backend.floatx() (floatx defaults to float32).

tf.keras.mixed_precision.global_policy()
<Policy "float32">
tf.keras.layers.Dense(10).dtype_policy  # Defaults to the global policy
<Policy "float32">

If TensorFlow 2 behavior has been disabled with tf.compat.v1.disable_v2_behavior(), this will instead return a special "_infer" policy which infers the dtype from the dtype of the first input the first time the layer is called. This behavior matches the behavior that existed in TensorFlow 1.

See tf.keras.mixed_precision.Policy for more information on policies.
