# vLLM Inference Scripts |
|
|
|
|
|
Ready-to-run scripts for GPU-accelerated inference using [vLLM](https://github.com/vllm-project/vllm). |
|
|
|
|
|
## 📋 Available Scripts |
|
|
|
|
|
### classify-dataset.py |
|
|
|
|
|
Batch text classification using BERT-style models with vLLM's optimized inference engine. |
|
|
|
|
|
**Features:** |
|
|
- 🚀 High-throughput batch processing |
|
|
- 🏷️ Automatic label mapping from model config |
|
|
- 📊 Confidence scores for predictions |
|
|
- 🤗 Direct integration with Hugging Face Hub |
|
|
|
|
|
**Usage:** |
|
|
```bash |
|
|
# Local execution (requires GPU) |
|
|
uv run classify-dataset.py \ |
|
|
davanstrien/ModernBERT-base-is-new-arxiv-dataset \ |
|
|
username/input-dataset \ |
|
|
username/output-dataset \ |
|
|
--inference-column text \ |
|
|
--batch-size 10000 |
|
|
``` |
|
|
|
|
|
**HF Jobs execution:** |
|
|
```bash |
|
|
hfjobs run \ |
|
|
--flavor l4x1 \ |
|
|
--secret HF_TOKEN=$(python -c "from huggingface_hub import HfFolder; print(HfFolder.get_token())") \ |
|
|
vllm/vllm-openai:latest \ |
|
|
/bin/bash -c ' |
|
|
uv run https://huggingface.co/datasets/uv-scripts/vllm/resolve/main/classify-dataset.py \ |
|
|
davanstrien/ModernBERT-base-is-new-arxiv-dataset \ |
|
|
username/input-dataset \ |
|
|
username/output-dataset \ |
|
|
--inference-column text \ |
|
|
--batch-size 100000 |
|
|
' \ |
|
|
--project vllm-classify \ |
|
|
--name my-classification-job |
|
|
``` |
|
|
|
|
|
## 🎯 Requirements |
|
|
|
|
|
All scripts in this collection require: |
|
|
- **NVIDIA GPU** with CUDA support |
|
|
- **Python 3.10+** |
|
|
- **UV package manager** (auto-installed via script) |
|
|
|
|
|
## 🚀 Performance Tips |
|
|
|
|
|
### GPU Selection |
|
|
- **L4 GPU** (`--flavor l4x1`): Best value for classification tasks |
|
|
- **A10 GPU** (`--flavor a10`): Higher memory for larger models |
|
|
- Adjust batch size based on GPU memory |
|
|
|
|
|
### Batch Sizes |
|
|
- **Local GPUs**: Start with 10,000 and adjust based on memory |
|
|
- **HF Jobs**: Can use larger batches (50,000-100,000) with cloud GPUs |
|

## 📚 About vLLM |
|
|
|
|
|
vLLM is a high-throughput inference engine optimized for: |
|
|
- Fast model serving with PagedAttention |
|
|
- Efficient batch processing |
|
|
- Support for various model architectures |
|
|
- Seamless integration with Hugging Face models |
|
|
|
|
|
## 🔧 Technical Details |
|
|
|
|
|
### Dependencies |
|
|
Scripts use vLLM's nightly builds and FlashInfer for optimal performance: |
|
|
```python |
|
|
# [[tool.uv.index]] |
|
|
# url = "https://flashinfer.ai/whl/cu126/torch2.6" |
|
|
# |
|
|
# [[tool.uv.index]] |
|
|
# url = "https://wheels.vllm.ai/nightly" |
|
|
``` |
|
|
|
|
|
### Docker Image |
|
|
For HF Jobs, we use the official vLLM Docker image: `vllm/vllm-openai:latest` |
|
|
|
|
|
This image includes: |
|
|
- Pre-installed CUDA libraries |
|
|
- vLLM and all dependencies |
|
|
- UV package manager |
|
|
- Optimized for GPU inference |
|
|
