In this tutorial, you will use LMI container from DLC to SageMaker and run inference with it.

Please make sure the following permission granted before running the notebook:

• SageMaker access

Step 1: Let's bump up SageMaker and import stuff

%pip install sagemaker --upgrade  --quiet

import sagemaker
from sagemaker.djl_inference.model import DJLModel

role = sagemaker.get_execution_role()  # execution role for the endpoint
session = sagemaker.session.Session()  # sagemaker session for interacting with different AWS APIs

Step 2: Start building SageMaker endpoint

In this step, we will build SageMaker endpoint from scratch

Getting the container image URI (optional)

Check out available images: Large Model Inference available DLC

# Choose a specific version of LMI image directly:
# image_uri = "763104351884.dkr.ecr.us-west-2.amazonaws.com/djl-inference:0.28.0-lmi10.0.0-cu124"

Create SageMaker model

Here we are using LMI PySDK to create the model.

Checkout more configuration options.

model_id = "codellama/CodeLlama-34b-hf" # model will be download form Huggingface hub

env = {
    "TENSOR_PARALLEL_DEGREE": "4",            # requires 4 GPUs, set to "max" to use all GPUs on the instance
    "OPTION_ROLLING_BATCH": "auto",           # optional, enabled by default
}

model = DJLModel(
    model_id=model_id,
    env=env,
    role=role)

Create SageMaker endpoint

You need to specify the instance to use and endpoint names

instance_type = "ml.g5.12xlarge"
endpoint_name = sagemaker.utils.name_from_base("lmi-model")

predictor = model.deploy(initial_instance_count=1,
             instance_type=instance_type,
             endpoint_name=endpoint_name,
             # container_startup_health_check_timeout=3600
            )

Step 3: Run inference

predictor.predict(
    {"inputs": "import socket\n\ndef ping_exponential_backoff(host: str):", "parameters": {"max_new_tokens":128, "do_sample":"true"}}
)

Clean up the environment

session.delete_endpoint(endpoint_name)
session.delete_endpoint_config(endpoint_name)
model.delete_model()
