Convenience function to add an addition layer to a graph

Store a profiling context returned from a backend that support profiling, and register its counters

Marks the given subgraph as a direct antecedent (dependency) of this one.

Utility function used to check if a vector of tensors are Signed32

* Assigns a color to each label in the label set */

BatchToSpaceND Operator

Creates a simple subgraph with only one convolution layer, supported by the mock backend

Creates a subgraph with five convolutions layers, all supported by the mock backend

Creates a subgraph with only unoptimizable layers ("unoptimizable" is added to the layer's name)

Creates a subgraph containing only a single unsupported layer (only convolutions are unsupported by the mock backend)

Creates a subgraph containing only unsupported layers (only convolutions are unsupported by the mock backend)

Creates a subgraph with some unoptimizable layers ("unoptimizable" is added to the layer's name)

Creates a subgraph with some input unoptimizable layers ("unoptimizable" is added to the layer's name), this is meant to test input slots coming from

Creates a subgraph with both supported and unsupported layers (only convolutions are unsupported by the mock backend)

For all handle factories supported on the source backend, we wish to find the one which requires the fewest copies when considering all connections.

Find the handle factory for the input layer which results in fewest required copies.

Find the handle factory for the output layer which results in fewest required copies.
