Hi @ywpratama, just so you know: tutorial failures might not be caused by your new code here. There was a bug introduced with a recent version of plotnine. To remedy, you could e.g. replicate c796cc5. This is, however, only a temporary fix and if you don't mind the tutorials failing for now, some new version will probably fix the bug in the not-too-far future.

Same goes for individual tests that really look like they should be passing. We are currently trying to fix this flakiness in #784.
