// Compares two TensorFlow graphs to see if their meaning is the same. This is a
|
|
// semantic comparison that's intended to show whether the graphs should produce
|
|
// the same results, and so ignores details like version numbers or node
|
|
// ordering that don't affect the output. To use it, run something like this:
|
|
//
|
|
// bazel build tensorflow/tools/graph_transforms:compare_graphs
|
|
// bazel-bin/tensorflow/tools/graph_transforms/compare_graphs a.pb b.pb
|
|
//
|
|
// The return value is 0 if the graphs are equal, 1 if they're different, and -1
|
|
// if there was a problem.
