Ah yes, this comes from a bug in the argument parser that will be fixed by this PR 8. Basically greater_is_better is stored as a string and not a bool, so the tests using it don’t give the right results.
Since you are using eval_loss, it will default to False if you don’t say anything, so a workaround while you wait for the fix is to remove --greater_is_better False \ in your command.
