验证量化模型#

请注意，您需要将从 Hugging Face 下载的原始模型的 config.json 文件中的 "quantization_config.config_groups.group_0.targets" 的值从 ["Linear"] 修改为 ["MoE"]。

{
  "quantization_config": {
    "config_groups": {
      "group_0": {
        "targets": [
          "MoE"
        ]
      }
    }
  }
}

您的模型文件看起来是这样的

|-- configuration_deepseek.py
|-- configuration.json
|-- generation_config.json
|-- model-00001-of-000062.safetensors

在多 NPU 上进行在线推理#

运行以下脚本在 Multi-NPU 上启动 vLLM 服务器

对于 Atlas 800 A3 (64G*16) 节点，tensor-parallel-size 至少应为 16。

vllm serve Kimi-K2-Thinking \
--served-model-name kimi-k2-thinking \
--tensor-parallel-size 16 \
--enable_expert_parallel \
--trust-remote-code \
--no-enable-prefix-caching

服务器启动后，您可以使用输入提示查询模型。

curl https://:8000/v1/chat/completions -H "Content-Type: application/json" -d '{
  "model": "kimi-k2-thinking",
  "messages": [
    {"role": "user", "content": "Who are you?"}
  ],
  "temperature": 1.0
}'
