## BLEURT
|
2 |
+
|
3 |
+
Pytorch version of the original BLEURT models from ACL paper ["BLEURT: Learning Robust Metrics for Text Generation"](https://aclanthology.org/2020.acl-main.704/) by
|
4 |
+
Thibault Sellam, Dipanjan Das and Ankur P. Parikh of Google Research.

The code for model conversion was originated from [this notebook](https://colab.research.google.com/drive/1KsCUkFW45d5_ROSv2aHtXgeBa2Z98r03?usp=sharing) mentioned [here](https://github.com/huggingface/datasets/issues/224).

## Usage Example
|
9 |
+
|
10 |
+
```python
|
11 |
+
from transformers import BertForSequenceClassification, AutoTokenizer
|
12 |
+
import torch
|
13 |
+
|
14 |
+
tokenizer = AutoTokenizer.from_pretrained("elron/bleurt-large-512")
|
15 |
+
model = AutoModelForSequenceClassification.from_pretrained("elron/bleurt-large-512")
|
16 |
+
model.eval()
|
17 |
+
|
18 |
+
references = ["hello world", "hello world"]
|
19 |
+
candidates = ["hi universe", "bye world"]
|
20 |
+
|
21 |
+
with torch.no_grad():
|
22 |
+
scores = model(**tokenizer(references, candidates, return_tensors='pt'))[0]
|
23 |
+
|
24 |
+
print(scores) # tensor([[0.9877], [0.0475]])
|
25 |
+
```
