drivanov commented on issue #16218: Improving performance of argmax operator URL: https://github.com/apache/incubator-mxnet/pull/16218#issuecomment-534635929 @access2rohit: - When building I do not use any special tricks. flags, etc. I just launch `make`. - For banchmark I am using ``` def test_argmax() ``` from `/opt/mxnet/tests/python/unittest/test_operator.py` and I launch it by using following command: ``` nosetests --verbose -s --logging-level=DEBUG /opt/mxnet/tests/python/unittest/test_operator.py:test_argmax ``` (BTW, `--logging-level=DEBUG` option needed to see the seed which is used by the test for randomly generated tensors. Otherwise the seed will be printed only if test should fail, which is not a case for this benchmark) - To make the results 100% reproducible or/and benchmark different `argmax`'s with the same set of randomly tensors, you need to use the same seed. For instance, for the benchmark I did for your #16178, I was using `MXNET_TEST_SEED=1643676822`. If you want to reproduce these results, just call: ``` > export MXNET_TEST_SEED=1643676822 > nosetests --verbose -s --logging-level=DEBUG /opt/mxnet/tests/python/unittest/test_operator.py:test_argmax ``` BTW, - if you will need to use another randomly used seed, just call ``` > unset MXNET_TEST_SEED ``` before launching `nosetests --verbose -s --logging-level=DEBUG ...`.
