Fix #20243
Actually, #20243 works as expected in torch and jax backends without this PR. The underlying issue in TF backend has been resolved.
The root cause was that we used
pop
in_filter_unused_inputs
withinCompileLoss
, which is not allowed in a jitted tf graph. The solution is to avoid modifying the incoming data.A test has been added to verify the implementation.
