VPC images

To quickly pull an ACS AI container image within a VPC, replace the specified AI container image asset URI egslingjun-registry.cn-wulanchabu.cr.aliyuncs.com/egslingjun/{image:tag} with acs-registry-vpc.{region-id}.cr.aliyuncs.com/egslingjun/{image:tag}.

{region-id}: The region ID of an available region for ACS products. Examples: cn-beijing and cn-wulanchabu.
{image:tag}: The name and tag of the AI container image. Examples: inference-nv-pytorch:25.10-vllm0.11.0-pytorch2.8-cu128-20251028-serverless and training-nv-pytorch:25.10-serverless.

Note

These images are applicable to ACS products and Lingjun multi-tenant products. Do not use them in Lingjun single-tenant scenarios.

Driver requirements

CUDA 12.8: NVIDIA driver version >= 570
CUDA 13.0: NVIDIA driver version >= 580

Quick start

The following example shows how to pull the inference-nv-pytorch image using Docker and test the inference service with the Qwen2.5-7B-Instruct model.

Note

To use the inference-nv-pytorch image in ACS, you can select the image on the Artifacts page when you create a workload in the console, or specify the image reference in a YAML file. For more information, see the following topics about how to build a model inference service using ACS GPU computing power:

Pull the inference container image.

docker pull egslingjun-registry.cn-wulanchabu.cr.aliyuncs.com/egslingjun/inference-nv-pytorch:[tag]

Download the open source model from ModelScope.

pip install modelscope
cd /mnt
modelscope download --model Qwen/Qwen2.5-7B-Instruct --local_dir ./Qwen2.5-7B-Instruct

Run the following command to enter the container.

docker run -d -t --network=host --privileged --init --ipc=host \
--ulimit memlock=-1 --ulimit stack=67108864  \
-v /mnt/:/mnt/ \
egslingjun-registry.cn-wulanchabu.cr.aliyuncs.com/egslingjun/inference-nv-pytorch:[tag]

Run an inference test on the vLLM conversational inference feature.

Start the server-side service.

python3 -m vllm.entrypoints.openai.api_server \
--model /mnt/Qwen2.5-7B-Instruct \
--trust-remote-code --disable-custom-all-reduce \
--tensor-parallel-size 1

Run a test on the client.

curl http://localhost:8000/v1/chat/completions \
    -H "Content-Type: application/json" \
    -d '{
    "model": "/mnt/Qwen2.5-7B-Instruct",  
    "messages": [
    {"role": "system", "content": "You are a friendly AI assistant."},
    {"role": "user", "content": "Tell me about deep learning."}
    ]}'

For more information about how to use vLLM, see vLLM.

Known issues

The deepgpu-comfyui plugin, which accelerates video generation for the Wanx model, supports only the GN8IS, G49E, and G59 instance types.
SGLang 0.5.5.post3 fails to run the DeepSeek-R1 model on L20A/L20C instances and returns the error TypeError: Mismatched type on argument #17 when calling: `trtllm_fp8_block_scale_moe. For more information, see the related issue in the open source community.
