# deberta-v3-large for Extractive QA |
|
|
|
This is the [deberta-v3-large](https://huggingface.co/microsoft/deberta-v3-large) model, fine-tuned using the [SQuAD2.0](https://huggingface.co/datasets/squad_v2) dataset. It's been trained on question-answer pairs, including unanswerable questions, for the task of Extractive Question Answering. |
|
|
|
This model was trained using LoRA available through the [PEFT library](https://github.com/huggingface/peft). |
|
|
|
## Overview |
|
**Language model:** deberta-v3-large |
|
**Language:** English |
|
**Downstream-task:** Extractive QA |
|
**Training data:** SQuAD 2.0 |
|
**Eval data:** SQuAD 2.0 |
|
**Infrastructure**: 1x NVIDIA 3070 |
|
|
|
## Model Usage |
|
|
|
### Using Transformers |
|
This uses the merged weights (base model weights + LoRA weights) to allow for simple use in Transformers pipelines. It has the same performance as using the weights separately when using the PEFT library. |
|
```python |
|
import torch |
|
from transformers import( |
|
AutoModelForQuestionAnswering, |
|
AutoTokenizer, |
|
pipeline |
|
) |
|
model_name = "sjrhuschlee/deberta-v3-large-squad2" |
|
|
|
# a) Using pipelines |
|
nlp = pipeline('question-answering', model=model_name, tokenizer=model_name) |
|
qa_input = { |
|
'question': 'Where do I live?', |
|
'context': 'My name is Sarah and I live in London' |
|
} |
|
res = nlp(qa_input) |
|
# {'score': 0.984, 'start': 30, 'end': 37, 'answer': ' London'} |
|
|
|
# b) Load model & tokenizer |
|
model = AutoModelForQuestionAnswering.from_pretrained(model_name) |
|
tokenizer = AutoTokenizer.from_pretrained(model_name) |
|
|
|
question = 'Where do I live?' |
|
context = 'My name is Sarah and I live in London' |
|
encoding = tokenizer(question, context, return_tensors="pt") |
|
start_scores, end_scores = model( |
|
encoding["input_ids"], |
|
attention_mask=encoding["attention_mask"], |
|
return_dict=False |
|
) |
|
|
|
all_tokens = tokenizer.convert_ids_to_tokens(input_ids[0].tolist()) |
|
answer_tokens = all_tokens[torch.argmax(start_scores):torch.argmax(end_scores) + 1] |
|
answer = tokenizer.decode(tokenizer.convert_tokens_to_ids(answer_tokens)) |
|
# 'London' |
|
``` |
|
|

### Using with Peft |
|
**NOTE**: This requires code in the PR https://github.com/huggingface/peft/pull/473 for the PEFT library. |
|
```python |
|
#!pip install peft |
|
|
|
from peft import LoraConfig, PeftModelForQuestionAnswering |
|
from transformers import AutoModelForQuestionAnswering, AutoTokenizer |
|
model_name = "sjrhuschlee/deberta-v3-large-squad2" |
|
``` |
|
|
