This is a sentence-transformers model: It maps sentences & paragraphs to a 1024 dimensional dense vector space and can be used for tasks like clustering or semantic search.

Usage (HuggingFace Transformers)
Without sentence-transformers, 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
1from transformers import AutoTokenizer, AutoModel
2import torch
345defcls_pooling(model_output, attention_mask):6return model_output[0][:,0]789# Sentences we want sentence embeddings for10sentences =['This is an example sentence','Each sentence is converted']1112# Load model from HuggingFace Hub13tokenizer = AutoTokenizer.from_pretrained('{MODEL_NAME}')14model = AutoModel.from_pretrained('{MODEL_NAME}')1516# Tokenize sentences17encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')1819# Compute token embeddings20with torch.no_grad():21 model_output = model(**encoded_input)2223# Perform pooling. In this case, cls pooling.24sentence_embeddings = cls_pooling(model_output, encoded_input['attention_mask'])2526print("Sentence embeddings:")27print(sentence_embeddings)
