But serializing compute dags +and matching them efficiently is not easy. Therefore, we use the above string to encode a compute +dag. +These strings are efficient for serialization/matching and wont' be too long. +When we need the dag, we decode the string and call the function, which will return the dag. +""" + +import pickle +import json + +import tvm._ffi +from .utils import serialize_args, deserialize_args + +WORKLOAD_FUNC_REGISTRY = {} + + +def register_workload(func): + """ Register a workload by generation function. + + The input function should take hashable and jsonable arguments + (int, float, tuple of int, tvm.tensor.Tensor, ...) and return a list of tvm.tensor.Tensor. + + Parameters + ---------- + func : Function + The target function that returns the compute declaration Tensors.
