Usage
from transformers import DPRQuestionEncoder, DPRQuestionEncoderTokenizer
tokenizer = DPRQuestionEncoderTokenizer.from_pretrained('firqaaa/indo-dpr-question_encoder-multiset-base')
model = DPRQuestionEncoder.from_pretrained('firqaaa/indo-dpr-question_encoder-multiset-base')
input_ids = tokenizer("Siapakah tokoh antagonis terkuat dalam serial DragonBall Super?", return_tensors='pt')["input_ids"]
embeddings = model(input_ids).pooler_output
