Can't find "gen_training_ops" in the tensorflow GitHub

Question

I'm working on a new optimizer, and I managed to work out most of the process. Only thing I'm stuck on currently is finding gen_training_ops.

Apparently this file is crucial, because in both implementations of Gradient Descent, and Adagrad optimizers they use functions that are imported out of a wrapper file for gen_training_ops (training_ops.py in the python/training folder). I can't find this file anywhere, so I suppose I don't understand something and search in the wrong place. Where can I find it? (Or specifically the implementations of apply_adagrad and apply_gradient_descent)

Thanks a lot :)

The file seems to be generated https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/BUILD#L912 — martianwars, Dec 22 '16 at 14:42
You can find it on your local disk by using `inspect.getsourcefile`, some more background -- http://stackoverflow.com/a/41149557/419116 — Yaroslav Bulatov, Dec 22 '16 at 18:10

The file will be generated when you build TensorFlow from source. It is marked as out in this file,

If you find it, youll realize it just jumps to pyhon/framework, where the actual update is just an assign operation and then gets grouped
