## How to use the model |
|
|
|
### With the zero-shot classification pipeline |
|
|
|
The model can be loaded with the `zero-shot-classification` pipeline like so: |
|
|
|
```python |
|
from transformers import pipeline |
|
classifier = pipeline("zero-shot-classification", |
|
model="mjwong/bge-large-en-mnli-anli") |
|
``` |
|
|
|
You can then use this pipeline to classify sequences into any of the class names you specify. |
|
|
|
```python |
|
sequence_to_classify = "one day I will see the world" |
|
candidate_labels = ['travel', 'cooking', 'dancing'] |
|
classifier(sequence_to_classify, candidate_labels) |
|
``` |
|
|
|
If more than one candidate label can be correct, pass `multi_class=True` to calculate each class independently: |
|
|
|
```python |
|
candidate_labels = ['travel', 'cooking', 'dancing', 'exploration'] |
|
classifier(sequence_to_classify, candidate_labels, multi_class=True) |
|
``` |
|
|
|
### With manual PyTorch |
|
|
|
The model can also be applied on NLI tasks like so: |
|
|
|
```python |
|
import torch |
|
from transformers import AutoTokenizer, AutoModelForSequenceClassification |
|
# device = "cuda:0" or "cpu" |
|
device = torch.device("cuda") if torch.cuda.is_available() else torch.device("cpu") |
|
model_name = "mjwong/bge-large-en-mnli-anli" |
|
tokenizer = AutoTokenizer.from_pretrained(model_name) |
|
model = AutoModelForSequenceClassification.from_pretrained(model_name) |
|
premise = "But I thought you'd sworn off coffee." |
|
hypothesis = "I thought that you vowed to drink more coffee." |
|
input = tokenizer(premise, hypothesis, truncation=True, return_tensors="pt") |
|
output = model(input["input_ids"].to(device)) |
|
prediction = torch.softmax(output["logits"][0], -1).tolist() |
|
label_names = ["entailment", "neutral", "contradiction"] |
|
prediction = {name: round(float(pred) * 100, 2) for pred, name in zip(prediction, label_names)} |
|
print(prediction) |
|
``` |
|
|
|
### Eval results |
|
The model was also evaluated using the dev sets for MultiNLI and test sets for ANLI. The metric used is accuracy. |
