Code issue

[pzw1231]

I run the following code：

python train.py --dataset foods --split_ratio 0.25 --seed 0
--train_type base
--backbone bert --classifier_type softmax --optimizer adam_vanilla \

Encountered the following problem：

Loading pre-trained backbone network...
Initializing dataset and model...
Initializing base dataset... (name: foods)
Training model...
Traceback (most recent call last):

[MrSworder]

I have the same problem. It's beacuse of wrong version of transfomers.#1392
But after changing transformers' version, the torch will report a error: ImportError: cannot import name 'SAVE_STATE_WARNING' from 'torch.optim.lr_scheduler' when running preprocess.py( torch-1.9.0)

Please show the requirements.
