Embedding examples

Transformers

You can use RoBERTtcr with Transformers. To get started, install the necessary dependencies to setup your environment:

pip install -U transformers torch

Once setup you can proceed to run the model by running the snippet below:

from transformers import BertTokenizer, RobertaModel
import torch

device = 'cuda:0' if torch.cuda.is_available() else 'cpu'
tokenizer = BertTokenizer.from_pretrained('keiwoo/RoBERTtcr', do_lower_case = False)
model = RobertaModel.from_pretrained('keiwoo/RoBERTtcr').to(device)

outputs = model(**tokenizer(' '.join('CATAGGETQYF'), return_tensors="pt").to(device))

print(outputs.last_hidden_state[0].shape)
# torch.Size([13, 1024]) [CLS+N+SEP, 1024]
