## How to use the model |
|
|
|
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/e5-large-mnli") |
|
``` |
|
|
|
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) |
|
#{'sequence': 'one day I will see the world', |
|
# 'labels': ['travel', 'dancing', 'cooking'], |
|
# 'scores': [0.9494319558143616, 0.044598229229450226, 0.00596982054412365]} |
|
``` |
|
|
|
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) |
|
#{'sequence': 'one day I will see the world', |
|
# 'labels': ['exploration', 'travel', 'dancing', 'cooking'], |
|
# 'scores': [0.9918234944343567, |
|
# 0.9867327213287354, |
|
# 0.40335655212402344, |
|
# 0.0020157278049737215]} |
|
``` |
|
|
|
### Eval results |
