## Description ## Split operation can be done by multiple reorder primitives with properly set strides  Benchmark script: ``` import gc import mxnet import mxnet.gluon.nn as nn import mxnet.numpy as np import time dims = [128, 512, 1024] print("shape;axis;time") for ndim in range(2): for dim1 in dims: for dim2 in dims: shape = (dim1, dim2) if ndim == 0 else (8, dim1, dim2) a = np.random.uniform(-1.0, 1.0, shape).astype(np.float32) for axis in range(2 + ndim): for section in (2, 4, 8): tic = time.time() for i in range(100): out = np.array_split(a, axis=axis, indices_or_sections=section) [o.wait_to_read() for o in out] toc = time.time() gc.collect() print(f"{shape};{axis};{section};{toc-tic}") ``` -- This is an automated message from the Apache Git Service.
