tf.distribute.experimental_set_strategy

TensorFlow 2 version View source on GitHub

Set a tf.distribute.Strategy as current without with strategy.scope().

tf.distribute.experimental_set_strategy(
    strategy
)

tf.distribute.experimental_set_strategy(strategy1)
f()
tf.distribute.experimental_set_strategy(strategy2)
g()
tf.distribute.experimental_set_strategy(None)
h()

is equivalent to:

with strategy1.scope():
  f()
with strategy2.scope():
  g()
h()

In general, you should use the with strategy.scope(): API, but this alternative may be convenient in notebooks where you would have to put each cell in a with strategy.scope(): block.

strategy A tf.distribute.Strategy object or None.

RuntimeError If called inside a with strategy.scope():.
