Context manager for testing forward compatibility of generated graphs.
@tf_contextlib.contextmanager
tf.compat.forward_compatibility_horizon( year, month, day )
To ensure forward compatibility of generated graphs (see forward_compatible
)
with older binaries, new features can be gated with:
if compat.forward_compatible(year=2018, month=08, date=01):
generate_graph_with_new_features()
else:
generate_graph_so_older_binaries_can_consume_it()
However, when adding new features, one may want to unittest it before the forward compatibility window expires. This context manager enables such tests. For example:
from tensorflow.python.compat import compat
def testMyNewFeature(self):
with compat.forward_compatibility_horizon(2018, 08, 02):
# Test that generate_graph_with_new_features() has an effect
