Model description
BERTbase fine-tuned on SQuAD 2.0 : Encoder-based Transformer Language model, pretrained with Masked Language Modeling and Next Sentence Prediction.
Suitable for Question-Answering tasks, predicts answer spans within the context provided.
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 -
!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.
"""
question = "Which deep learning libraries back 🤗 Transformers?"
