### vllm推理方法
#### server 多机
1. 加入环境变量
> 请注意：
> 每个节点上的环境变量都写到.sh文件中，保存后各个计算节点分别source `.sh` 文件
>
> VLLM_HOST_IP：节点本地通信口ip，尽量选择IB网卡的IP，**避免出现rccl超时问题**
>
> NCCL_SOCKET_IFNAME和GLOO_SOCKET_IFNAME：节点本地通信网口ip对应的名称
>
> 通信口和ip查询方法：ifconfig
>
> IB口状态查询：ibstat !!!一定要active激活状态才可用，各个节点要保持统一
<div align=center>
<img src="./doc/ip_bw.png"/>
</div>
```bash
export ALLREDUCE_STREAM_WITH_COMPUTE=1
export VLLM_HOST_IP=x.x.x.x # 对应计算节点的IP，建议选择IB口SOCKET_IFNAME对应IP地址
export NCCL_SOCKET_IFNAME=ibxxxx
export GLOO_SOCKET_IFNAME=ibxxxx
export NCCL_IB_HCA=mlx5_0:1 # 环境中的IB网卡名字

#BW集群需要额外设置的环境变量：
export NCCL_NET_GDR_LEVEL=7
export NCCL_SDMA_COPY_ENABLE=0
export VLLM_RPC_TIMEOUT=1800000
``` ```
2. 进行模型划分 2. 启动RAY集群
> x.x.x.x 对应第一步 Master节点的 VLLM_HOST_IP
```bash ```bash
python convert.py --hf-ckpt-path /path/to/DeepSeek-V3.2-Exp-bf16 --save-path /path/to/DeepSeek-V3.2-Demo --n-experts 256 --model-parallel 32 # head节点执行

# worker节点执行
ray start --address='x.x.x.x:6379' --num-gpus=8 --num-cpus=32
``` ```
> 注意：需要将/path/to/DeepSeek-V3.2-Exp中的json文件复制到/path/to/DeepSeek-V3.2-Demo中。
3. 启动推理 3. 启动vllm server
> intel cpu 需要加参数：`--enforce-eager`

# DeepSeek V3.2
First convert huggingface model weights to the the format required by our inference demo. Set `MP` to match your available GPU count:
```bash
cd inference
export EXPERTS=256
python convert.py --hf-ckpt-path ${HF_CKPT_PATH} --save-path ${SAVE_PATH} --n-experts ${EXPERTS} --model-parallel ${MP}
```
Launch the interactive chat interface and start exploring DeepSeek's capabilities:
```bash
export CONFIG=config_671B_v3.2.json
torchrun --nproc-per-node ${MP} generate.py --ckpt-path ${SAVE_PATH} --config ${CONFIG} --interactive
```
