* This file defines IRPassManager, it helps control the passes in IR. Inference
|
|
* phrase will load the model program and parameters from disk, that is quite
|
|
* different from the training phase.
|
|
* This manager will control the Passes and make the passes in IR work smoothly
|
|
* for inference.
