|
|
|
**Language model:** bert-base-uncased |
|
**Language:** English |
|
**Downstream-task:** Question-Answering |
|
**Training data:** Train-set SQuAD 2.0 |
|
**Evaluation data:** Evaluation-set SQuAD 2.0 |
|
**Hardware Accelerator used**: GPU Tesla T4 |
|
|
|
## Intended uses & limitations |
|
|
|
For Question-Answering - |
|
|
|
```python |
|
!pip install transformers |
|
from transformers import pipeline |
|
|
|
model_checkpoint = "IProject-10/bert-base-uncased-finetuned-squad2" |
|
question_answerer = pipeline("question-answering", model=model_checkpoint) |
|
|
|
context = """ |
|
🤗 Transformers is backed by the three most popular deep learning libraries — Jax, PyTorch and TensorFlow — with a seamless integration |
|
between them. It's straightforward to train your models with one before loading them for inference with the other. |
