示例

运行ERNIE-4.5-300B-A47B-Paddle

启动服务

基于 WINT4 精度和 32K 上下文部署 ERNIE-4.5-300B-A47B-Paddle 模型到 4 卡 P800 服务器

export XPU_VISIBLE_DEVICES="0,1,2,3" # 设置使用的 XPU 卡
python -m fastdeploy.entrypoints.openai.api_server \
    --model PaddlePaddle/ERNIE-4.5-300B-A47B-Paddle \
    --port 8188 \
    --tensor-parallel-size 4 \
    --max-model-len 32768 \
    --max-num-seqs 64 \
    --quantization "wint4" \
    --gpu-memory-utilization 0.9

注意： 使用 P800 在 4 块 XPU 上进行部署时，由于受到卡间互联拓扑等硬件限制，仅支持以下两种配置方式： export XPU_VISIBLE_DEVICES="0,1,2,3" or export XPU_VISIBLE_DEVICES="4,5,6,7"

更多参数可以参考参数说明。

全部支持的模型可以在上方的 支持的模型 章节找到。

请求服务

您可以基于 OpenAI 协议，通过 curl 和 python 两种方式请求服务。

curl -X POST "http://0.0.0.0:8188/v1/chat/completions" \
-H "Content-Type: application/json" \
-d '{
  "messages": [
    {"role": "user", "content": "Where is the capital of China?"}
  ]
}'

import openai
host = "0.0.0.0"
port = "8188"
client = openai.Client(base_url=f"http://{host}:{port}/v1", api_key="null")

response = client.completions.create(
    model="null",
    prompt="Where is the capital of China?",
    stream=True,
)
for chunk in response:
    print(chunk.choices[0].text, end='')
print('\n')

response = client.chat.completions.create(
    model="null",
    messages=[
        {"role": "user", "content": "Where is the capital of China?"},
    ],
    stream=True,
)
for chunk in response:
    if chunk.choices[0].delta:
        print(chunk.choices[0].delta.content, end='')
print('\n')

OpenAI 协议的更多说明可参考文档 OpenAI Chat Completion API，以及与 OpenAI 协议的区别可以参考兼容 OpenAI 协议的服务化部署。
