Returns an Op that initializes all tables of the default graph.
tf.compat.v1.tables_initializer(
name='init_all_tables'
)
Migrate to TF2
tf.compat.v1.tables_initializer
is no longer needed with eager execution and
tf.function
. In TF2, when creating an initializable table like a
tf.lookup.StaticHashTable
, the table will automatically be initialized on
creation.
Before & After Usage Example
Before:
with tf.compat.v1.Session():
init = tf.compat.v1.lookup.KeyValueTensorInitializer(['a', 'b'], [1, 2])
table = tf.compat.v1.lookup.StaticHashTable(init, default_value=-1)
tf.compat.v1.tables_initializer().run()
result = table.lookup(tf.constant(['a', 'c'])).eval()
result
array([ 1, -1], dtype=int32)
After:
init = tf.lookup.KeyValueTensorInitializer(['a', 'b'], [1, 2])
table = tf.lookup.StaticHashTable(init, default_value=-1)
table.lookup(tf.constant(['a', 'c'])).numpy()
array([ 1, -1], dtype=int32)
