From 0d0ea0735cdf19ad9db3743855927a292694f7b5 Mon Sep 17 00:00:00 2001 From: Sait Cakmak Date: Fri, 10 Nov 2023 17:24:52 -0800 Subject: [PATCH] Fix & temporarily disable raytune tutorial, print tutorial execution errors & memory usage (#1974) Summary: The tutorials script has been updated to mimic the setup in the BoTorch script to print out the errors encountered while running the tutorials. The raytune tutorial mysteriously fails even after fixing the deprecation errors, so we'll temporarily remove it from the CI. The early stopping tutorial fails trial execution both when run locally and with this diff, so that's also disabled temporarily. The tutorial changes address the deprecation warning / error: ``` DeprecationWarning: `tune.report` is deprecated. Use `ray.train.report` instead -- see the example below: from ray import tune -> from ray import train tune.report(metric=1) -> train.report({'metric': 1}) ``` Also reduces # of trials from 30 to 10. Pull Request resolved: https://github.com/facebook/Ax/pull/1974 Test Plan: Ran `python scripts/make_tutorials.py -w $(pwd) -e -s` locally and checked the outputs (including with added errors in the tutorials).
