argument --optimizer: invalid choice: 'adam_ood' (choose from 'adam_vanilla', 'adam_masker')

[MrSworder]

In readme, there is a command : python train.py --dataset review --split_ratio 0.25 --seed 0
--train_type base
--backbone bert --classifier_type softmax --optimizer adam_ood \

But in the code, train.py, there is no option adam_ood.
