# Introduce
## Installation 🔥
- We recommend `python 3.9` or higher, `torch 2.0.0` or higher, `transformers 4.31.0` or higher.
- Currently, you can only download from the source, however, in the future, we will upload it to PyPI. RagE can be installed from source with the following commands:
```
git clone https://github.com/anti-aii/RagE.git
cd RagE
pip install -e .
```
## Quick start 🥮
- [1. Initialize the model](#initialize_model)
- [2. Load model from Huggingface Hub](#download_hf)
- [3. List of pretrained models](#list_pretrained)
We have detailed instructions for using our models for inference. See [notebook](notebook)
### 1. Initialize the model
<a name= 'initialize_model'></a>
Let's initalize the SentenceEmbedding model
```python
>>> import torch
>>> from pyvi import ViTokenizer
>>> from rage import SentenceEmbedding
>>> device= torch.device('cuda' if torch.cuda.is_available() else 'cpu')
>>> model= SentenceEmbedding(model_name= "vinai/phobert-base-v2", torch_dtype= torch.float32, aggregation_hidden_states= False, strategy_pooling= "dense_first")
>>> model.to(device)
SentenceEmbeddingConfig(model_base: {'model_type_base': 'RobertaModel', 'model_name': 'vinai/phobert-base-v2', 'type_backbone': 'mlm', 'required_grad_base_model': True, 'aggregation_hidden_states': False, 'concat_embeddings': False, 'dropout': 0.1, 'quantization_config': None}, pooling: {'strategy_pooling': 'dense_first'})
```
Then, we can show the number of parameters in the model.
```python
>>> model.summary_params()
trainable params: 135588864 || all params: 135588864 || trainable%: 100.0
>>> model.summary()
+---------------------------+-------------+------------------+
| Layer (type) | Params | Trainable params |
+---------------------------+-------------+------------------+
| model (RobertaModel) | 134,998,272 | 134998272 |
| pooling (PoolingStrategy) | 590,592 | 590592 |
| drp1 (Dropout) | 0 | 0 |
+---------------------------+-------------+------------------+
```
Now we can use the SentenceEmbedding model to encode the input words. The output of the model will be a matrix in the shape of (batch, dim). Additionally, we can load weights that we have previously trained and saved.
``` python
>>> model.load("best_sup_general_embedding_phobert2.pt", key= False)
>>> sentences= ["Tôi đang đi học", "Bạn tên là gì?",]
>>> sentences= list(map(lambda x: ViTokenizer.tokenize(x), sentences))
>>> model.encode(sentences, batch_size= 1, normalize_embedding= "l2", return_tensors= "np", verbose= 1)
2/2 [==============================] - 0s 43ms/Sample
array([[ 0.00281098, -0.00829096, -0.01582766, ..., 0.00878178,
0.01830498, -0.00459659],
[ 0.00249859, -0.03076724, 0.00033016, ..., 0.01299141,
-0.00984358, -0.00703243]], dtype=float32)
```
### 2. Load model from Huggingface Hub
<a name= 'download_hf'> </a>
First, download a pretrained model.
```python
>>> model= SentenceEmbedding.from_pretrained('anti-ai/VieSemantic-base')
```
Then, we encode the input sentences and compare their similarity.
```python
>>> sentences = ["Nó rất thú_vị", "Nó không thú_vị ."]
>>> output= model.encode(sentences, batch_size= 1, return_tensors= 'pt')
>>> torch.cosine_similarity(output[0].view(1, -1), output[1].view(1, -1)).cpu().tolist()
2/2 [==============================] - 0s 40ms/Sample
[0.5605039596557617]
```
### 3. List of pretrained models
<a name= 'list_pretrained'></a>
This list will be updated with our prominent models. Our models will primarily aim to support Vietnamese language.
