Thanks for your contribution! Looks good overall! Just to be sure, could we have a unit test to ensure the equal length split is correctly supported. I can see the changes in file test_cases but that isn't a unit test per se right?

Thanks for reviewing @ChaiBapchya. The tests listed in test_cases.py are ONNX operator unit test cases . These test operator import/export. These are different from the operator test cases written in tests/python/unittest/test_operator.py of MXNet.
