Environment Setup
Basic Requirements
- GPU: You need an NVIDIA GPU like A100 or H100, or an AMD GPU.
- Memory: Your system should have at least 32GB of memory, more is better.
- Operating System: Use Linux, Ubuntu 20.04 or later is recommended.
- Python: Make sure you have Python 3.8 or later installed.
Code and Model Preparation
- Clone the Official Repository
First, clone the DeepSeek V3 repository:bashCopygit clone https://github.com/deepseek-ai/DeepSeek-V3.git cd DeepSeek-V3/inference pip install -r requirements.txt
- Download Model Weights
- Get the official model weights from HuggingFace.
- Put the weight files in the right directory.
Deployment Options
1. DeepSeek-Infer Demo Deployment
This method is great for fast testing and trying things out:
python convert.py --hf-ckpt-path /path/to/DeepSeek-V3 \ --save-path /path/to/DeepSeek-V3-Demo \ --n-experts 256 \ --model-parallel 16 torchrun --nnodes 2 --nproc-per-node 8 generate.py \ --node-rank $RANK \ --master-addr $ADDR \ --ckpt-path /path/to/DeepSeek-V3-Demo \ --config configs/config_671B.json \ --interactive \ --temperature 0.7 \ --max-new-tokens 200
2. SGLang Deployment (Recommended)
SGLang v0.4.1 is the best choice for several reasons:
- It supports MLA optimization.
- It supports FP8 (W8A8).
- It supports FP8 KV cache.
- It supports Torch Compile.
- It works with both NVIDIA and AMD GPUs.
3. LMDeploy Deployment (Recommended)
LMDeploy is top-notch for big deployments, offering:
- Offline pipeline processing.
- Online service deployment.
- PyTorch workflow integration.
- Optimized inference performance.
4. TRT-LLM Deployment (Recommended)
TensorRT-LLM is great because it includes:
- BF16 and INT4/INT8 weight support.
- Soon, it will support FP8.
- It boosts inference speed.
5. vLLM Deployment (Recommended)
vLLM v0.6.6 is a top pick, offering:
- FP8 and BF16 mode support.
- Works with NVIDIA and AMD GPUs.
- Pipeline parallelism capability.
- Multi-machine distributed deployment.
