## Usage
### Direct Usage (Sentence Transformers)
First install the Sentence Transformers library:
```bash
pip install -U sentence-transformers
```
Then you can load this model and run inference.
```python
from sentence_transformers import SentenceTransformer
# Download from the 🤗 Hub
model = SentenceTransformer("calvin2258000/test2")
# Run inference
sentences = [
'Appendix A:Key terms ..... 11Appendix B:Standards referred to ..... 12# Approved Document P:Electrical safety Dwellings## Summary0.1 This approved document gives guidance on how to comply with Part P of the Building Regulations.It contains the following sections:Section 1:Technical requirements for electrical work in dwellingsSection 2:The types of building and electrical installation within the scope of Part P, and the types of electrical work that are notifiableSection 3:The different procedures that may be followed to show that electrical work complies with Part PAppendix A:Key terms',
'What guidance does Approved Document P provide for complying with Part P of the Building Regulations regarding electrical work in dwellings?',
"What conditions classify a district heat network as 'under construction' based on the building regulations defined on 15 June 2022?",
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]
# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
