Fixed an error where autograph({expr}) would error when exporting undef
active binding symbols.
for in an eager autograph() context gains the ability to process
arbitrary python iterables, including tf.distribute.DistributedDataset.
for now automatically infers the variables of nested for loops as loop vars.
Improved error message when a break or next is signaled as a graph node
but the intended loop is being evaluated eagerly.
devtools::load_all()shape_invariants supplied to ag_while_opts. A named list of user variable shapes can be passed directly now, without requiring users to manually specify shapes of internal loop tracking tensors.back_prop arg in ag_while_opts()NEWS.md file to track changes to the package.
