## **🤖 InternSVG Model**
|
| 21 |
|
| 22 |
+
The **InternSVG-8B** model is available at [Hugging Face](https://huggingface.co/InternSVG/InternSVG-8B). It is based on the InternVL3-8B model, incorporating SVG-specific tokens, and undergoes Supervised Fine-Tuning (SFT) under a two-stage training strategy using the massive SVG training samples from the SAgoge dataset.
|
| 23 |
+
|
| 24 |
+
### Deploy
|
| 25 |
+
|
| 26 |
+
We recommend using [LMDeploy](https://github.com/InternLM/lmdeploy) for deployment. An example of launching a proxy server with 8 parallel workers (one per GPU) is provided below:
|
| 27 |
+
|
| 28 |
+
```bash
|
| 29 |
+
#!/bin/bash
|
| 30 |
+
model_path="MODEL_PATH"
|
| 31 |
+
model_name="InternSVG"
|
| 32 |
+
|
| 33 |
+

|
| 34 |
+

|
| 37 |
+
for ((i = 0; i < worker_num; i++)); do
|
| 38 |
+

|

### Train
|
| 53 |
+
|
| 54 |
+
If you need to train your own model, please follow these steps:
|
| 55 |
+
|
| 56 |
+
1. **Prepare the Dataset:** Download the **SAgoge** dataset. After that, update the paths for the SAgoge-related subdatasets in `LLaMA-Factory/data/dataset_info.json` to match your local file paths.
|
| 57 |
+
2. **Download InternVL3-8B:** Download the InternVL3-8B from [link](https://huggingface.co/OpenGVLab/InternVL3-8B-hf).
|
| 58 |
+
3. **Add Special Tokens:** Before training, you must add SVG-specific tokens to the base model. Run the `utils/add_token.py` script, which adds these special tokens to the original model weights and initializes their embeddings based on subwords.
|
| 59 |
+
4. **Start Training:** We provide example configuration scripts for the two-stage training process. You can find them at:
|
| 60 |
+
- **Stage 1:** `LLaMA-Factory/examples/train_full/stage_1.yaml`
|
| 61 |
+
- **Stage 2:** `LLaMA-Factory/examples/train_full/stage_2.yaml`
|
| 62 |
+
|
| 63 |
+
Then use `llamafactory-cli train` to start training.
