To use this function, you must use ResourceVariables (i.e.
`variable_scope(name, use_resource=True), which are the default in Eager mode
and when running on TPU.
Args
fn
a function that takes Tensors (all as positional arguments) and returns
a tuple of Tensors. Note that fn should not close over any other
Tensors or Variables.
use_data_dep
bool, if True will use a dummy data dependency to force
the recompute to happen. If False will use a control dependency. By
default will be True if in an XLA context and False otherwise. XLA
ignores control dependencies and so this data dependency is necessary.
tupleize_grads
bool, if True will use control dependencies to ensure
that all gradients are produced before any are consumed by downstream ops.
If use_data_dep is also True, will use a data dependency instead of
a control dependency.
Returns
A wrapped fn that is identical to fn when called, but its activations will
be discarded and recomputed on the backwards pass (i.e. on a call to
tf.gradients).
