DefaultCostModel(const std::string &weights_in_path, const std::string &weights_out_path, bool randomize_weights, Internal::Autoscheduler::Statistics &stats)
A templated Buffer class that wraps halide_buffer_t and adds functionality.
This file defines the class FunctionDAG, which is our representation of a Halide pipeline,...
