names, and can each have arguments themselves. These transforms define the
pipeline of modifications that are applied in order to produce the output.
Sometimes you need some transforms to happen before others, and the ordering
within the list lets you specify which happen first.

Note that the optimization
`remove_nodes(op=Identity, op=CheckNumerics)` will break the model with control
flow operations, such as `tf.cond`, `tf.map_fn`, and `tf.while`.
