Metax GPU Installation for running ERNIE 4.5 Series Models

The following installation methods are available when your environment meets these requirements: - Python >= 3.10 - Linux X86_64

Before starting, prepare a machine equipped with Enflame S60 accelerator cards. Requirements:

Chip Type Driver Version KMD Version
MetaX C550 3.0.0.1 2.14.6 
docker login --username=cr_temp_user --password=eyJpbnN0YW5jZUlkIjoiY3JpLXpxYTIzejI2YTU5M3R3M2QiLCJ0aW1lIjoiMTc1NTUxODEwODAwMCIsInR5cGUiOiJzdWIiLCJ1c2VySWQiOiIyMDcwOTQwMTA1NjYzNDE3OTIifQ:8226ca50ce5476c42062e24d3c465545de1c1780 cr.metax-tech.com && docker pull cr.metax-tech.com/public-library/maca-native:3.0.0.4-ubuntu20.04-amd64

2. paddlepaddle and custom device installation

1）pip install paddlepaddle==3.0.0.dev20250729 -i https://www.paddlepaddle.org.cn/packages/nightly/cpu/
2）pip install paddle-metax-gpu==3.0.0.dev20250807 -i https://www.paddlepaddle.org.cn/packages/nightly/maca/

3. Build Wheel from Source

Then clone the source code and build:

git clone https://github.com/PaddlePaddle/FastDeploy
cd FastDeploy
bash build.sh

The built packages will be in the FastDeploy/dist directory.

4. Environment Verification

After installation, verify the environment with this Python code:

import paddle
from paddle.jit.marker import unified
# Verify GPU availability
paddle.utils.run_check()
# Verify FastDeploy custom operators compilation
from fastdeploy.model_executor.ops.gpu import beam_search_softmax

If the above code executes successfully, the environment is ready.

5. Demo

from fastdeploy import LLM, SamplingParams

prompts = [ "Hello. My name is", ]

sampling_params = SamplingParams(top_p=0.95, max_tokens=32, temperature=0.6)

llm = LLM(model="/root/model/ERNIE-4.5-21B-A3B-Paddle", tensor_parallel_size=1, max_model_len=256, engine_worker_queue_port=9135, quantization='wint8', static_decode_blocks=0, gpu_memory_utilization=0.9)

outputs = llm.generate(prompts, sampling_params)

print(f"Generated {len(outputs)} outputs") print("=" * 50 + "\n")

for output in outputs: prompt = output.prompt generated_text = output.outputs.text print(prompt) print(generated_text) print("-" * 50)
