nGraph Debug Capabilities

nGraph representation provides an API to get detailed information about the graph structure.

To receive additional messages about applied graph modifications, rebuild the nGraph library with the -DNGRAPH_DEBUG_ENABLE=ON option.

To visualize the nGraph function to the xDot format or to an image file, use the ngraph::pass::VisualizeTree graph transformation pass:

#include <ngraph/pass/visualize_tree.hpp>

std::shared_ptr<ngraph::Function> nGraph;
...
ngraph::pass::VisualizeTree("after.png").run_on_function(nGraph);     // Visualize the nGraph function to an image
