Hi, i just run a tensorflow model with TVM. My model has 321 inputs so i find create NDArray inputs for model is time consuming.
Code:
is used in function NDArray.empty when create NDArray. If dtype is numpy.dtype, function DataType will convert it to str, and i find this convert is time consuming, about 0.83ms for my model.
So i use a table to avoid convert numpy.dtype to str.
