### Usage
```python
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
```
You can use it using `haystack` as follows:
```
from haystack.nodes import DensePassageRetriever
from haystack.document_stores import InMemoryDocumentStore
retriever = DensePassageRetriever(document_store=InMemoryDocumentStore(),
query_embedding_model="firqaaa/indo-dpr-question_encoder-multiset-base",
passage_embedding_model="firqaaa/indo-dpr-question_encoder-multiset-base",
max_seq_len_query=64,
max_seq_len_passage=256,
batch_size=16,
use_gpu=True,
embed_title=True,
use_fast_tokenizers=True)
```
