# Sentence Embeddings with `distilbert-zwnj-wnli-mean-tokens`
|
||||
|
||||
## Usage (Sentence-Transformers)
|
||||
Using this model becomes easy when you have [sentence-transformers](https://www.SBERT.net) installed:
|
||||
|
||||
```
|
||||
pip install -U sentence-transformers
|
||||
```
|
||||
|
||||
Then you can use the model like this:
|
||||
|
||||
```python
|
||||
from sentence_transformers import SentenceTransformer
|
||||
|
||||
|
||||
sentences = [
|
||||
'اولین حکمران شهر بابل کی بود؟',
|
||||
'در فصل زمستان چه اتفاقی افتاد؟',
|
||||
'میراث کوروش'
|
||||
]
|
||||
model = SentenceTransformer('m3hrdadfi/distilbert-zwnj-wnli-mean-tokens')
|
||||
embeddings = model.encode(sentences)
|
||||
print(embeddings)
|
||||
```
|
||||
|
||||
## Usage (HuggingFace Transformers)
|
||||
Without [sentence-transformers](https://www.SBERT.net), you can use the model like this: First, you pass your input through the transformer model, then you have to apply the right pooling-operation on-top of the contextualized word embeddings.
|
||||
|
||||
```python
|
||||
from transformers import AutoTokenizer, AutoModel
|
||||
import torch
|
||||
|
||||
|
||||
# Max Pooling - Take the max value over time for every dimension.
|
||||
def max_pooling(model_output, attention_mask):
|
||||
token_embeddings = model_output[0] #First element of model_output contains all token embeddings
|
||||
input_mask_expanded = attention_mask.unsqueeze(-1).expand(token_embeddings.size()).float()
|
||||
token_embeddings[input_mask_expanded == 0] = -1e9 # Set padding tokens to large negative value
|
||||
return torch.mean(token_embeddings, 1)[0]
|
||||
|
||||
# Sentences we want sentence embeddings for
|
||||
sentences = [
|
||||
'اولین حکمران شهر بابل کی بود؟',
|
||||
'در فصل زمستان چه اتفاقی افتاد؟',
|
||||
'میراث کوروش'
|
||||
]
|
||||
|
||||
# Load model from HuggingFace Hub
|
||||
tokenizer = AutoTokenizer.from_pretrained('m3hrdadfi/distilbert-zwnj-wnli-mean-tokens')
|
||||
model = AutoModel.from_pretrained('m3hrdadfi/distilbert-zwnj-wnli-mean-tokens')
|
||||
|
||||
# Tokenize sentences
|
||||
encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')
|
||||
# Compute token embeddings
|
||||
with torch.no_grad():
|
||||
model_output = model(**encoded_input)
|
||||
# Perform pooling. In this case, max pooling.
|
||||
sentence_embeddings = max_pooling(model_output, encoded_input['attention_mask'])
|
||||
|
||||
print("Sentence embeddings:")
|
||||
print(sentence_embeddings)
|
||||
```
