## Usage
|
|
### In Transformers
|
|
```python
|
|
from transformers import AutoModelForQuestionAnswering, AutoTokenizer, pipeline
|
|
|
|
model_name = "batterydata/batteryscibert-cased-squad-v1"
|
|
# a) Get predictions
|
|
nlp = pipeline('question-answering', model=model_name, tokenizer=model_name)
|
|
QA_input = {
|
|
'question': 'What is the electrolyte?',
|
|
'context': 'The typical non-aqueous electrolyte for commercial Li-ion cells is a solution of LiPF6 in linear and cyclic carbonates.'
|
|
}
|
|
res = nlp(QA_input)
|
|
# b) Load model & tokenizer
|
|
model = AutoModelForQuestionAnswering.from_pretrained(model_name)
|
|
tokenizer = AutoTokenizer.from_pretrained(model_name)
|
|
```
