Typeerror with ContextualWordEmbsAug

[zhangyaqi20]

Hi, I was using nlpaug.augmenter.word.context_word_embs.ContextualWordEmbsAug to augment my text with bert embeddings.

Here is my code:

import torch
import nlpaug.augmenter.word.context_word_embs as naw

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
aug = naw.ContextualWordEmbsAug(
    model_path='bert-base-uncased',
    model_type='bert',
    action='substitute',
    aug_p=0.1,
    aug_min=1,
    aug_max=10,
    device=device.type, # 'cpu' or 'cuda'
    )

text = "try this text for aug"
augmented_text = aug.augment(data=text, n=10)
print("Original:")
print(text)
print("Augmented Text:")
print(augmented_text)

But I got this error:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

     13 text = "try this text for aug"
---> 14 augmented_text = aug.augment(data=text, n=10)
     15 print("Original:")
     16 print(text)

    146                 idxes = idxes.detach().numpy().tolist()

TypeError: argument of type 'torch.device' is not iterable

Could you help me with this?

Thank you!
