Returns the global dtype policy.
tf.keras.mixed_precision.global_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.
