-# Cross-Encoder for Natural Language Inference
-This model was trained using [SentenceTransformers](https://sbert.net) [Cross-Encoder](https://www.sbert.net/examples/applications/cross-encoder/README.html) class.
-
-## Training Data
-The model was trained on the [SNLI](https://nlp.stanford.edu/projects/snli/) and [MultiNLI](https://cims.nyu.edu/~sbowman/multinli/) datasets. For a given sentence pair, it will output three scores corresponding to the labels: contradiction, entailment, neutral.
-
-## Performance
-For evaluation results, see [SBERT.net - Pretrained Cross-Encoder](https://www.sbert.net/docs/pretrained_cross-encoders.html#nli).
-
-## Usage
-
-Pre-trained models can be used like this:
-```python
-from sentence_transformers import CrossEncoder
-model = CrossEncoder('cross-encoder/nli-MiniLM2-L6-H768')
-scores = model.predict([('A man is eating pizza', 'A man eats something'), ('A black race car starts up in front of a crowd of people.', 'A man is driving down a lonely road.')])
-
-#Convert scores to labels
-label_mapping = ['contradiction', 'entailment', 'neutral']
-labels = [label_mapping[score_max] for score_max in scores.argmax(axis=1)]
-```
-
-## Usage with Transformers AutoModel
-You can use the model also directly with Transformers library (without SentenceTransformers library):
-```python
-from transformers import AutoTokenizer, AutoModelForSequenceClassification
-import torch
-
-model = AutoModelForSequenceClassification.from_pretrained('cross-encoder/nli-MiniLM2-L6-H768')
-tokenizer = AutoTokenizer.from_pretrained('cross-encoder/nli-MiniLM2-L6-H768')
-
-features = tokenizer(['A man is eating pizza', 'A black race car starts up in front of a crowd of people.'], ['A man eats something', 'A man is driving down a lonely road.'],  padding=True, truncation=True, return_tensors="pt")
-
-model.eval()
-with torch.no_grad():
-    scores = model(**features).logits
-    label_mapping = ['contradiction', 'entailment', 'neutral']
-    labels = [label_mapping[score_max] for score_max in scores.argmax(dim=1)]
-    print(labels)
-```
-
-## Zero-Shot Classification
-This model can also be used for zero-shot-classification:
-```python
-from transformers import pipeline
-
-classifier = pipeline("zero-shot-classification", model='cross-encoder/nli-MiniLM2-L6-H768')
-
-sent = "Apple just announced the newest iPhone X"
-candidate_labels = ["technology", "sports", "politics"]
-res = classifier(sent, candidate_labels)
-print(res)
