v23.08.00: adding unit test for end-to-end example (#669)
* adding unit test for multi-gpu example * added test for notebook 03 * fixed formatting * update * update * Update 01-ETL-with-NVTabular.ipynb day of week is between 0 and 6; it must be scaled with a max value of 6 to produce correct values from the 0-1 range. If we do col+1 and scale with 7, then a section of the 0-2pi range (for Sine purposes) will not be represented. * Update 01-ETL-with-NVTabular.ipynb Reversed the previous edit for weekday scaling. It is correct that it should be scaled between 0-7, because day 0 (unused/nonapplicable after +1 added) overlaps with day 7 for Sine purposes. Monday should scale to 1/7, Sunday should scale to 7/7 to achieve even distribution of days along the sinus curve. * reduce num_rows * Update test_end_to_end_session_based.py * Update 01-ETL-with-NVTabular.ipynb * updated test script and notebook * updated file * removed nb3 test due to multi-gpu freezing issue * revised notebooks, added back nb3 test * fixed test file with black * update test py * update test py * Use `python -m torch.distributed.run` instead of `torchrun` The `torchrun` script installed in the system is a python script with a shebang line starting with `#!/usr/bin/python3` This picks up the wrong version of python when running in a virtualenv like our tox test environment. If instead this were `#!/usr/bin/env python3` it would work ok in a tox environment to call `torchrun`. However, until either the pytorch package is updated for this to happen or we update our CI image for this to take place. Running the python command directly is more reliable. --------- Co-authored-by: rnyak <ronayak@hotmail.com> Co-authored-by: edknv <109497216+edknv@users.noreply.github.com> Co-authored-by: rnyak <16246900+rnyak@users.noreply.github.com> Co-authored-by: Oliver Holworthy <1216955+oliverholworthy@users.noreply.github.com>
