Graph transformation functionality:

  • Removing ops
  • Replacing ops
  • Renaming variables
  • Reinitializing parameters
  • Changing connection structure

We already have the ability to convert variables to constants, and back.

There are 2 use cases that having graph transformation functionality would be useful:

  1. For transfer learning ("replace output layer(s)") etc
  2. For import use cases

With regard to import: I've recently run into a model that I can't clean up in TF: I either run into model freezing bugs (in TF 1.12, maybe fixed in 1.13) or end up with training-specific nodes still in the graph that make it useless (no placeholders, but IteratorV2 and similar ops instead)
