In order to run this experiment on low RAM GPU you should select small model and tune context window (increasing context increase memory consumption). For example, running this ollama example on repurposed mining GPU with 6Gb of RAM required to set context size to 26k while using `gemma2:2b`. It was able to find 197 entities and 19 relations on `book.txt`.

<summary> <b>Using Vietnamese Embedding Model</b> </summary>
|
||||
|
||||
LightRAG supports the **AITeamVN/Vietnamese_Embedding** model, which is fine-tuned from BGE-M3 for enhanced Vietnamese retrieval.
|
||||
|
||||
**Model Details:**
|
||||
- Base: BAAI/bge-m3
|
||||
- Output Dimensions: 1024
|
||||
- Max Sequence Length: 2048 tokens
|
||||
- Language: Vietnamese (also supports other languages)
|
||||
- Training: ~300,000 Vietnamese query-document triplets
|
||||
|
||||
**Setup:**
|
||||
|
||||
1. Set your HuggingFace token:
|
||||
```bash
|
||||
export HUGGINGFACE_API_KEY="your_hf_token"
|
||||
# or
|
||||
export HF_TOKEN="your_hf_token"
|
||||
```
|
||||
|
||||
2. Use the Vietnamese embedding in your code:
|
||||
|
||||
```python
|
||||
import asyncio
|
||||
from lightrag import LightRAG, QueryParam
|
||||
from lightrag.llm.openai import gpt_4o_mini_complete
|
||||

|
||||
working_dir="./vietnamese_rag_storage",
|
||||
llm_model_func=gpt_4o_mini_complete,
|
||||
embedding_func=EmbeddingFunc(
|
||||
embedding_dim=1024, # Vietnamese_Embedding outputs 1024 dimensions
|
||||
max_token_size=2048, # Model supports up to 2048 tokens
|
||||
func=lambda texts: vietnamese_embed(
|
||||
texts,
|
||||
model_name="AITeamVN/Vietnamese_Embedding",
|
||||
token=your_hf_token # or None to read from environment
|
||||
)
|
||||
),
|
||||
)
|
||||
|
||||
await rag.initialize_storages()
|
||||

return rag
|
||||
|
||||
async def main():
|
||||
rag = await initialize_rag()
|
||||
|
||||
# Insert Vietnamese text
|
||||
await rag.ainsert("Việt Nam là một quốc gia nằm ở Đông Nam Á.")
|
||||
|
||||
# Query in Vietnamese
|
||||
result = await rag.aquery(
|
||||
"Việt Nam ở đâu?",
|
||||
param=QueryParam(mode="hybrid")
|
||||
)
|
||||
print(result)
|
||||
|
||||
await rag.finalize_storages()

||||
## Performance Considerations
|
||||
|
||||
### Memory Requirements
|
||||
- GPU Memory: ~2-4 GB
|
||||
- RAM: ~4-8 GB recommended
|
||||
- Disk Space: ~2 GB (model weights)
|
||||
|
||||
### Speed (on typical GPU)
|
||||
- Short texts (< 512 tokens): ~1000 texts/second
|
||||
- Longer texts (1024-2048 tokens): ~200-400 texts/second
|
||||
|
||||
### Optimization Tips
|
||||
1. Use GPU for significant speed improvement (10-50x faster)
|
||||
2. Batch requests together
|
||||
3. Model is cached after first download
|
||||
4. Adjust max_length for shorter texts if applicable
|
||||
|
||||
## Code Quality
|
||||
|
||||
All files pass syntax validation:
|
||||
```bash
|
||||
✓ lightrag/llm/vietnamese_embed.py
|
||||
✓ examples/vietnamese_embedding_demo.py
|
||||
✓ examples/lightrag_vietnamese_embedding_simple.py
|
||||
✓ tests/test_vietnamese_embedding_integration.py

||||
|
||||
You need a HuggingFace token to access the model:
|
||||
|
||||
```bash
|
||||
export HUGGINGFACE_API_KEY="your_hf_token_here"
|
||||
# or
|
||||
export HF_TOKEN="your_hf_token_here"
|
||||
```
|
||||
|
||||
Get your token from: https://huggingface.co/settings/tokens
|
||||
|
||||
## Quick Start
|

|
||||
|
||||
## API Reference
|
||||
|
||||
### `vietnamese_embed()`
|
||||
|
||||
Generate embeddings for texts using the Vietnamese Embedding model.
|
||||
|
||||
```python
|
||||
async def vietnamese_embed(
|
||||
texts: list[str],
|
||||
model_name: str = "AITeamVN/Vietnamese_Embedding",
|
||||
token: str | None = None,
|
||||
) -> np.ndarray
|
||||
```
|
||||
|
||||
**Parameters:**
|
||||
- `texts` (list[str]): List of texts to embed
|
||||
- `model_name` (str): HuggingFace model identifier
|
||||
- `token` (str, optional): HuggingFace API token (reads from env if not provided)
|
||||
|
||||
**Returns:**
|
||||
- `np.ndarray`: Array of embeddings with shape (len(texts), 1024)
|
||||
|
||||
**Example:**
|
||||
```python
|
||||
from lightrag.llm.vietnamese_embed import vietnamese_embed
|
||||
|
||||
texts = ["Xin chào", "Hello", "你好"]
|
||||
embeddings = await vietnamese_embed(texts)
|
||||
print(embeddings.shape) # (3, 1024)
|
||||
```
|
||||
|
||||
### `vietnamese_embedding_func()`
|
||||
|
||||
Convenience wrapper that automatically reads token from environment.
|
||||
|
||||
```python
|
||||
async def vietnamese_embedding_func(texts: list[str]) -> np.ndarray
|
||||
```
|
||||
|
||||
**Example:**
|
||||
```python
|
||||
from lightrag.llm.vietnamese_embed import vietnamese_embedding_func
|
||||
|
||||
# Token automatically read from HUGGINGFACE_API_KEY or HF_TOKEN
|
||||
embeddings = await vietnamese_embedding_func(["Xin chào"])
|
||||
```
|
||||
|
||||
## Advanced Usage
|
||||
|
||||
### Custom Model Configuration
|
||||
|
||||
```python
|
||||
from lightrag.llm.vietnamese_embed import vietnamese_embed
|
||||
|
||||
# Use a different model based on BGE-M3
|
||||
embeddings = await vietnamese_embed(
|
||||
texts=["Sample text"],
|
||||
model_name="BAAI/bge-m3", # Use base model
|
||||
token=your_token
|
||||
)
|
||||
```
|
||||
|
||||
### Device Selection
|
||||
|
||||
The model automatically detects and uses the best available device:
|
||||
1. CUDA (if available)
|
||||
2. MPS (for Apple Silicon)
|
||||
3. CPU (fallback)
|
||||
|
||||
You can check which device is being used by enabling debug logging:
|
||||
|
||||
```python
|
||||
from lightrag.utils import setup_logger
|
||||
|
||||
setup_logger("lightrag", level="DEBUG")
|
||||
```
|
||||
|
||||
### Batch Processing
|
||||
|
||||
The embedding function supports efficient batch processing:
|
||||
|
||||
```python
|
||||
# Process multiple texts efficiently
|
||||
large_batch = ["Text 1", "Text 2", ..., "Text 1000"]
|
||||
embeddings = await vietnamese_embed(large_batch)
|
||||
```
|
||||
|
||||
## Integration with LightRAG Server
|
||||
|
||||
To use Vietnamese embedding with LightRAG Server, update your `.env` file:
|
||||
|
||||
```env
|
||||
# Vietnamese Embedding Configuration
|
||||
EMBEDDING_MODEL=AITeamVN/Vietnamese_Embedding
|
||||
EMBEDDING_DIM=1024
|
||||
HUGGINGFACE_API_KEY=your_hf_token
|
||||
|
||||
# Or use custom binding
|
||||
EMBEDDING_BINDING=huggingface
|
||||
```
|
||||
|
||||
Then start the server:
|
||||
|
||||
```bash
|
||||
lightrag-server
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Memory Requirements
|
||||
|
||||
- **GPU Memory**: ~2-4 GB for the model
|
||||
- **RAM**: ~4-8 GB recommended
|
||||
- **Disk Space**: ~2 GB for model weights (cached after first download)
|
||||
|
||||
### Speed
|
||||
|
||||
On a typical GPU:
|
||||
- ~1000 texts/second for short texts (< 512 tokens)
|
||||
- ~200-400 texts/second for longer texts (1024-2048 tokens)
|
||||
|
||||
### Optimization Tips
|
||||
|
||||
1. **Use GPU**: Significantly faster than CPU (10-50x)
|
||||
2. **Batch Requests**: Process multiple texts together
|
||||
3. **Cache Model**: First run downloads model; subsequent runs are faster
|
||||
4. **Adjust max_length**: Use shorter max_length if your texts are shorter
|
||||
|
||||
```python
|
||||
# Example: Optimize for shorter texts
|
||||
embedding_func=EmbeddingFunc(
|
||||
embedding_dim=1024,
|
||||
max_token_size=512, # Reduce if texts are shorter
|
||||
func=lambda texts: vietnamese_embed(texts)
|
||||
)
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Issue: "No HuggingFace token found"
|
||||
|
||||
**Solution:** Set the environment variable:
|
||||
```bash
|
||||
export HUGGINGFACE_API_KEY="your_token"
|
||||
# or
|
||||
export HF_TOKEN="your_token"
|
||||
```
|
||||
|
||||
### Issue: "Model download fails"
|
||||
|
||||
**Solution:**
|
||||
1. Check your internet connection
|
||||
2. Verify your HuggingFace token is valid
|
||||
3. Ensure you have enough disk space (~2 GB)
|
||||
|
||||
### Issue: "Out of memory error"
|
||||
|
||||
**Solution:**
|
||||
1. Reduce batch size
|
||||
2. Use CPU instead of GPU (slower but uses less memory)
|
||||
3. Close other applications using GPU/RAM
|
||||
|
||||
### Issue: "Slow embedding generation"
|
||||
|
||||
**Solution:**
|
||||
1. Ensure you're using GPU (check logs for device info)
|
||||
2. Install CUDA-enabled PyTorch: `pip install torch --index-url https://download.pytorch.org/whl/cu118`
|
||||
3. Reduce max_token_size if your texts are shorter
|
||||
|
||||
## Comparison with Other Embedding Models

|
||||
|
||||
## 🔧 Advanced Topics
|
||||
|
||||
### Custom Model Configuration
|
||||
|
||||
Use a different HuggingFace model:
|
||||
|
||||
```python
|
||||
embeddings = await vietnamese_embed(
|
||||
texts=["Sample text"],
|
||||
model_name="BAAI/bge-m3", # Use base model
|
||||
token=your_token
|
||||
)
|
||||
```
|
||||
|
||||
### Device Management
|
||||
|
||||
The model automatically uses the best available device:
|
||||
1. CUDA (if available)
|
||||
2. MPS (for Apple Silicon)
|
||||
3. CPU (fallback)
|
||||
|
||||
Check which device is being used:
|
||||
|
||||
```python
|
||||
from lightrag.utils import setup_logger
|
||||
setup_logger("lightrag", level="DEBUG")
|
||||
# Will log: "Using CUDA device for embedding"
|
||||
```
|
||||
|
||||
### Memory Optimization
|
||||
|
||||
For limited memory environments:
|
||||
|
||||
```python
|
||||
# Reduce batch size
|
||||
embedding_func = EmbeddingFunc(
|
||||
embedding_dim=1024,
|
||||
max_token_size=512, # Reduce if texts are short
|
||||
func=vietnamese_embed
|
||||
)
|
||||
|
||||
# Process documents one at a time
|
||||
for doc in documents:
|
||||
await rag.ainsert(doc)
|
||||
```
|
||||
|
||||

|
||||
|
||||
## ⚡ Performance Tuning
|
||||
|
||||

|
||||
|
||||
### Performance Metrics
|
||||
|
||||
**GPU (NVIDIA RTX 3090):**
|
||||
- Short texts (< 512 tokens): ~1000 texts/second
|
||||
- Long texts (1024-2048 tokens): ~400 texts/second
|
||||
|
||||
**CPU (Intel i7):**
|
||||
- Short texts: ~50 texts/second
|
||||
- Long texts: ~20 texts/second
|
||||
|
||||
### Optimization Tips
|
||||
|
||||
1. **Use GPU:**
|
||||
```bash
|
||||
pip install torch --index-url https://download.pytorch.org/whl/cu118
|
||||
```
|
||||
|
||||
2. **Batch Processing:**
|
||||
```python
|
||||
# Good: Process in batch
|
||||
await rag.ainsert(multiple_documents)
|
||||
|
||||
# Avoid: One by one
|
||||
for doc in multiple_documents:
|
||||
await rag.ainsert(doc)
|
||||
```
|
||||
|
||||
3. **Adjust Token Size:**
|
||||
```python
|
||||
# If your texts are typically < 512 tokens
|
||||
embedding_func = EmbeddingFunc(
|
||||
embedding_dim=1024,
|
||||
max_token_size=512, # Faster processing
|
||||
func=vietnamese_embed
|
||||
)
|
||||
```
|
||||
|
||||
4. **Cache Model:**
|
||||
Model is cached after first download in `~/.cache/huggingface/`

## ❓ FAQ
|
||||
|
||||
### Q: Does this work with languages other than Vietnamese?
|
||||
|
||||
**A:** Yes! The model is based on BGE-M3 which supports 100+ languages. It's optimized for Vietnamese but works well with English, Chinese, and other languages.
|
||||
|
||||
### Q: Do I need GPU?
|
||||
|
||||
**A:** No, but highly recommended. CPU works but is 10-50x slower.
|
||||
|
||||
### Q: How much does it cost?
|
||||
|
||||
**A:** The embedding model is free. You only pay for the LLM API (e.g., OpenAI).
|
||||
|
||||
### Q: Can I use this offline?
|
||||
|
||||
**A:** After the first run (model download), the model is cached locally. You still need LLM API access though.
|
||||
|
||||
### Q: What's the difference from BGE-M3?
|
||||
|
||||
**A:** Vietnamese_Embedding is fine-tuned specifically for Vietnamese with 300K Vietnamese query-document pairs, providing better Vietnamese retrieval.
|
||||
|
||||
### Q: Can I fine-tune this model further?
|
||||
|
||||
**A:** Yes, you can fine-tune using HuggingFace transformers. See the model page for details.
|
||||
|
||||
### Q: Is my HuggingFace token safe?
|
||||
|
||||
**A:** The token is only used to download the model from HuggingFace. It's not sent anywhere else.
|
||||
|
||||
### Q: How do I switch back to other embeddings?
|
||||
|
||||
**A:** Just use a different embedding function in your configuration. No other changes needed.

|
||||
### Documentation
|
||||
- **English:** `docs/VietnameseEmbedding.md`
|
||||
- **Tiếng Việt:** `docs/VietnameseEmbedding_VI.md`
|
||||
|
||||
### Examples

|
||||
- **Comprehensive:** `examples/vietnamese_embedding_demo.py`
|
||||
|
||||
### Testing
|
||||
```bash
|
||||
python tests/test_vietnamese_embedding_integration.py
|
||||
```
|
||||
|
||||
## 🐛 Common Issues
|
||||
|
||||
### "No HuggingFace token found"
|
||||
```bash
|
||||
export HUGGINGFACE_API_KEY="your_token"
|
||||
```
|
||||
|
||||
### "Model download fails"
|
||||
- Check internet connection
|
||||
- Verify HuggingFace token is valid
|
||||
- Ensure 2GB+ free disk space
|
||||
|
||||
### "Out of memory"
|
||||
- Reduce batch size
|
||||
- Use CPU instead of GPU
|
||||
- Close other GPU applications
|
||||
|
||||
### "Slow embedding"
|
||||
- Install CUDA-enabled PyTorch
|
||||
- Check GPU is being used (see logs)
|
||||
- Reduce `max_token_size` for shorter texts
|
||||
|
||||
## 💡 Tips
|
||||
|
||||
1. **First run is slow:** Model downloads (~2GB), cached afterward
|
||||
2. **Use GPU:** 10-50x faster than CPU
|
||||
3. **Batch requests:** Process multiple texts together
|
||||
4. **Enable debug logs:** See device being used
|
||||
```python
|
||||
from lightrag.utils import setup_logger
|
||||
setup_logger("lightrag", level="DEBUG")
|
||||
```

## Bắt đầu nhanh
|
||||
|
||||
### Ví dụ đơn giản
|
||||
|
||||
```python
|
||||
import os
|
||||
import asyncio
|
||||
from lightrag import LightRAG, QueryParam
|
||||
from lightrag.llm.openai import gpt_4o_mini_complete

|
||||
|
||||
WORKING_DIR = "./vietnamese_rag_storage"
|
||||
|
||||
async def main():
|
||||
# Lấy HuggingFace token
|
||||
hf_token = os.environ.get("HUGGINGFACE_API_KEY")
|
||||
|
||||
# Khởi tạo LightRAG với Vietnamese embedding
|
||||
rag = LightRAG(
|
||||
working_dir=WORKING_DIR,

|
||||
func=lambda texts: vietnamese_embed(
|
||||
texts,
|
||||
model_name="AITeamVN/Vietnamese_Embedding",
|
||||
token=hf_token
|
||||
)
|
||||
),
|
||||
)
|
||||
|
||||
# Khởi tạo storage và pipeline
|
||||
await rag.initialize_storages()
|
||||
await initialize_pipeline_status()
|
||||
|
||||
# Chèn văn bản tiếng Việt
|
||||
await rag.ainsert("Việt Nam là một quốc gia nằm ở Đông Nam Á.")
|
||||
|
||||
# Truy vấn
|
||||
result = await rag.aquery(
|
||||
"Việt Nam ở đâu?",
|
||||
param=QueryParam(mode="hybrid")
|
||||
)
|
||||
print(result)
|
||||
|
||||
await rag.finalize_storages()
|
||||
|
||||
if __name__ == "__main__":
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
### Sử dụng với file `.env`
|
||||
|
||||
Tạo file `.env` trong thư mục dự án:
|
||||
|
||||
```env
|
||||
# HuggingFace Token cho Vietnamese Embedding
|
||||
HUGGINGFACE_API_KEY=
|
||||
|
||||
# Cấu hình LLM
|
||||
OPENAI_API_KEY=your_openai_key_here
|
||||
LLM_BINDING=openai
|
||||
LLM_MODEL=gpt-4o-mini
|
||||
|
||||
# Cấu hình Embedding
|
||||
EMBEDDING_MODEL=AITeamVN/Vietnamese_Embedding
|
||||
EMBEDDING_DIM=1024
|
||||
```
|
||||
|
||||
## Các script ví dụ
|
||||
|
||||
### 1. Ví dụ đơn giản
|
||||
```bash
|
||||
python examples/lightrag_vietnamese_embedding_simple.py
|
||||
```
|
||||
|
||||
Ví dụ tối thiểu về xử lý văn bản tiếng Việt.
|
||||
|
||||
### 2. Demo đầy đủ
|
||||
```bash
|
||||
python examples/vietnamese_embedding_demo.py
|
||||
```
|
||||
|
||||
Demo toàn diện bao gồm:
|
||||
- Xử lý văn bản tiếng Việt
|
||||
- Xử lý văn bản tiếng Anh (hỗ trợ đa ngôn ngữ)
|
||||
- Xử lý văn bản hỗn hợp
|
||||
- Nhiều ví dụ truy vấn
|
||||
|
||||
## Tài liệu API
|
||||
|
||||
### `vietnamese_embed()`
|
||||
|
||||
Tạo embeddings cho văn bản sử dụng mô hình Vietnamese Embedding.
|
||||
|
||||
```python
|
||||
async def vietnamese_embed(
|
||||
texts: list[str],
|
||||
model_name: str = "AITeamVN/Vietnamese_Embedding",
|
||||
token: str | None = None,
|
||||
) -> np.ndarray
|
||||
```
|
||||
|
||||
**Tham số:**
|
||||
- `texts` (list[str]): Danh sách các văn bản cần embedding
|
||||
- `model_name` (str): Tên mô hình trên HuggingFace
|
||||
- `token` (str, optional): HuggingFace API token (đọc từ env nếu không cung cấp)
|
||||
|
||||
**Trả về:**
|
||||
- `np.ndarray`: Mảng embeddings với shape (len(texts), 1024)
|
||||
|
||||
**Ví dụ:**
|
||||
```python
|
||||
from lightrag.llm.vietnamese_embed import vietnamese_embed
|
||||
|
||||
texts = ["Xin chào", "Tạm biệt", "Cảm ơn"]
|
||||
embeddings = await vietnamese_embed(texts)
|
||||
print(embeddings.shape) # (3, 1024)
|
||||
```
|
||||
|
||||
## Sử dụng nâng cao
|
||||
|
||||
### Lựa chọn thiết bị
|
||||
|
||||
Mô hình tự động phát hiện và sử dụng thiết bị tốt nhất:
|
||||
1. CUDA (nếu có)
|
||||
2. MPS (cho Apple Silicon)
|
||||
3. CPU (dự phòng)
|
||||
|
||||
Bật debug logging để xem thiết bị đang sử dụng:
|
||||
|
||||
```python
|
||||
from lightrag.utils import setup_logger
|
||||
|
||||
setup_logger("lightrag", level="DEBUG")
|
||||
```
|
||||
|
||||
### Xử lý batch
|
||||
|
||||
Hàm embedding hỗ trợ xử lý batch hiệu quả:
|
||||
|
||||
```python
|
||||
# Xử lý nhiều văn bản hiệu quả
|
||||
large_batch = ["Văn bản 1", "Văn bản 2", ..., "Văn bản 1000"]
|
||||
embeddings = await vietnamese_embed(large_batch)
|
||||
```
|
||||
|
||||
## Khắc phục sự cố
|
||||
|
||||
### Vấn đề: "No HuggingFace token found"
|
||||
|
||||
**Giải pháp:** Thiết lập biến môi trường:
|
||||
```bash
|
||||
export HUGGINGFACE_API_KEY="your_token"
|
||||
# hoặc
|
||||
export HF_TOKEN="your_token"
|
||||
```
|
||||
|
||||
### Vấn đề: "Model download fails"
|
||||
|
||||
**Giải pháp:**
|
||||
1. Kiểm tra kết nối internet
|
||||
2. Xác thực token HuggingFace hợp lệ
|
||||
3. Đảm bảo đủ dung lượng ổ đĩa (~2 GB)
|
||||
|
||||
### Vấn đề: "Out of memory error"
|
||||
|
||||
**Giải pháp:**
|
||||
1. Giảm kích thước batch
|
||||
2. Sử dụng CPU thay vì GPU (chậm hơn nhưng dùng ít bộ nhớ hơn)
|
||||
3. Đóng các ứng dụng khác đang dùng GPU/RAM
|
||||
|
||||
### Vấn đề: "Embedding generation chậm"
|
||||
|
||||
**Giải pháp:**
|
||||
1. Đảm bảo đang sử dụng GPU (kiểm tra logs)
|
||||
2. Cài đặt PyTorch với CUDA: `pip install torch --index-url https://download.pytorch.org/whl/cu118`
|
||||
3. Giảm max_token_size nếu văn bản ngắn hơn
|
||||
|
||||

|
||||
|
||||
## Prerequisites
|
||||
|
||||
### Required Environment Variables
|
||||
|
||||
```bash
|
||||
# HuggingFace token (required for model access)
|
||||
export HUGGINGFACE_API_KEY="hf_your_token_here"
|
||||
# or
|
||||
export HF_TOKEN="hf_your_token_here"
|
||||
|
||||
# LLM API key (using OpenAI as example)
|
||||
export OPENAI_API_KEY="sk-your_key_here"
|
||||
```
|
||||
|
||||
### Get Your Tokens
|
||||
|
||||
1. **HuggingFace Token:**
|
||||
- Visit: https://huggingface.co/settings/tokens
|
||||
- Create a new token with "Read" permission
|
||||
- Copy and export it
|
||||
|
||||
2. **OpenAI API Key:**
|
||||
- Visit: https://platform.openai.com/api-keys
|
||||
- Create a new key
|
||||
- Copy and export it
|
||||
|
||||
### Alternative: Use `.env` File
|
||||
|
||||
Create a `.env` file in the project root:
|
||||
|
||||
```env
|
||||
HUGGINGFACE_API_KEY=hf_your_token_here
|
||||
OPENAI_API_KEY=sk-your_key_here
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## What to Expect on First Run
|
||||
|
||||
### Model Download (First Time Only)
|
||||
- Size: ~2 GB
|
||||
- Time: 2-5 minutes (depending on internet speed)
|
||||
- Location: Cached in `~/.cache/huggingface/`
|
||||
|
||||
After the first run, the model is cached and loads instantly.
|
||||
|
||||
### Resource Usage
|
||||
- **GPU Memory:** 2-4 GB (if using GPU)
|
||||
- **RAM:** 4-8 GB
|
||||
- **Disk Space:** 2 GB for model + storage for RAG data
|
||||

|
||||
|
||||
## Common Issues & Solutions
|
||||
|
||||
### Issue: "No HuggingFace token found"
|
||||
**Solution:**
|
||||
```bash
|
||||
export HUGGINGFACE_API_KEY="your_token"
|
||||
```
|
||||
|
||||
### Issue: "Model download fails"
|
||||
**Possible causes:**
|
||||
1. No internet connection
|
||||
2. Invalid HuggingFace token
|
||||
3. Insufficient disk space
|
||||
|
||||
**Solution:**
|
||||
- Check internet connection
|
||||
- Verify token is correct
|
||||
- Ensure 2GB+ free space
|
||||
|
||||
### Issue: "Out of memory error"
|
||||
**Solution:**
|
||||
- Close other applications
|
||||
- Use CPU instead of GPU (slower but less memory)
|
||||
- Reduce batch size (if processing many texts)
|
||||
|
||||
### Issue: "Slow performance"
|
||||
**Solution:**
|
||||
- Install CUDA-enabled PyTorch for GPU support
|
||||
- Check GPU is being used (enable DEBUG logging)
|
||||
- Use GPU instead of CPU (10-50x faster)
|
||||
|
||||
---
|
||||
|
||||
## Tips for Best Results
|
||||
|
||||
### 1. Enable Debug Logging
|
||||
See what's happening under the hood:
|
||||
```python
|
||||
from lightrag.utils import setup_logger
|
||||
setup_logger("lightrag", level="DEBUG")
|
||||
```
|
||||
|
||||
### 2. Use GPU for Production
|
||||
Much faster than CPU:
|
||||
```bash
|
||||
# Install CUDA-enabled PyTorch
|
||||
pip install torch --index-url https://download.pytorch.org/whl/cu118
|
||||
```
|
||||
|
||||
### 3. Optimize for Your Use Case
|
||||
Adjust parameters based on your text length:
|
||||
```python
|
||||
embedding_func=EmbeddingFunc(
|
||||
embedding_dim=1024,
|
||||
max_token_size=1024, # Reduce if your texts are shorter
|
||||
func=vietnamese_embed
|
||||
)
|
||||
```
|
||||
|
||||
### 4. Batch Processing
|
||||
Process multiple texts together for efficiency:
|
||||
```python
|
||||
texts = ["Text 1", "Text 2", ..., "Text N"]
|
||||
await rag.ainsert(texts) # More efficient than one by one
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Understanding the Examples
|
||||
|
||||
### Key Components
|
||||
|
||||
1. **Embedding Function:**
|
||||
```python
|
||||
from lightrag.llm.vietnamese_embed import vietnamese_embed
|
||||
```
|
||||
This loads the Vietnamese_Embedding model.
|
||||
|
||||
2. **LightRAG Configuration:**
|
||||
```python
|
||||
embedding_func=EmbeddingFunc(
|
||||
embedding_dim=1024, # Vietnamese_Embedding outputs 1024 dimensions
|
||||
max_token_size=2048, # Model supports up to 2048 tokens
|
||||
func=vietnamese_embed # The embedding function
|
||||
)
|
||||
```
|
||||
|
||||
3. **Text Insertion:**
|
||||
```python
|
||||
await rag.ainsert(text) # Asynchronous insertion
|
||||
# or
|
||||
rag.insert(text) # Synchronous insertion
|
||||
```
|
||||
|
||||
4. **Querying:**
|
||||
```python
|
||||
result = await rag.aquery(
|
||||
query,
|
||||
param=QueryParam(mode="hybrid") # hybrid, local, global, naive, mix
|
||||
)
|
||||
```
|
||||
|
||||
### Query Modes
|
||||
|
||||
- **naive:** Simple vector similarity search
|
||||
- **local:** Context-dependent retrieval
|
||||
- **global:** Global knowledge retrieval
|
||||
- **hybrid:** Combines local and global
|
||||
- **mix:** Integrates knowledge graph and vector retrieval
|
||||
|
||||
For Vietnamese text, **hybrid** mode typically works best.

|
||||
|
||||
## Modifying the Examples
|
||||
|
||||
### Use Different LLM
|
||||
|
||||
Replace `gpt_4o_mini_complete` with your preferred LLM:
|
||||
|
||||
```python
|
||||
# Using Ollama
|
||||
from lightrag.llm.ollama import ollama_model_complete
|
||||
llm_model_func=ollama_model_complete
|
||||
|
||||
# Using Azure OpenAI
|
||||
from lightrag.llm.azure_openai import azure_openai_complete
|
||||
llm_model_func=azure_openai_complete
|
||||
```
|
||||
|
||||
### Use Different Embedding Model
|
||||
|
||||
While keeping the Vietnamese embedding:
|
||||
|
||||
```python
|
||||
from lightrag.llm.vietnamese_embed import vietnamese_embed
|
||||
|
||||
# Use different model from HuggingFace
|
||||
func=lambda texts: vietnamese_embed(
|
||||
texts,
|
||||
model_name="BAAI/bge-m3", # Use base model
|
||||
token=hf_token
|
||||
)
|
||||
```
|
||||
|
||||
### Add Your Own Data
|
||||
|
||||
Replace the sample text with your own:
|
||||
|
||||
```python
|
||||
# Read from file
|
||||
with open("your_data.txt", "r", encoding="utf-8") as f:
|
||||
text = f.read()
|
||||
|
||||
await rag.ainsert(text)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||

Artificial Intelligence (AI) is transforming the world in unprecedented ways.
|
||||
|
||||
Machine Learning, a subset of AI, enables computers to learn from data without explicit programming.
|
||||
Deep Learning uses neural networks with multiple layers to process complex patterns.
|
||||
|
||||
Natural Language Processing (NLP) allows machines to understand and generate human language.
|
||||
Popular NLP models include:
|
||||
- GPT (Generative Pre-trained Transformer) for text generation
|
||||
