Custom fine-tuned model gets weird results

[penguinwang96825]

I'm experiencing unusual results with the custom fine-tuned model textattack/roberta-base-SST-2. The clean accuracy is significantly lower than expected, at 50.69%. I've included the attack results below, which show a low accuracy under attack and a high number of skipped attacks. I'd appreciate it if you could look into this issue.

I'm also encountering an issue with the bert-base-uncased model fine-tuned on several datasets. It suddenly behaves abnormally. I've tried reinstalling TextAttack, but the problem persists.
