Hugging Face

Hugging Face Estimator

class sagemaker.huggingface.HuggingFace(py_version, entry_point, transformers_version=None, tensorflow_version=None, pytorch_version=None, source_dir=None, hyperparameters=None, image_uri=None, distribution=None, compiler_config=None, **kwargs)

Bases: sagemaker.estimator.Framework

Handle training of custom HuggingFace code.

This Estimator executes a HuggingFace script in a managed execution environment.

The managed HuggingFace environment is an Amazon-built Docker container that executes functions defined in the supplied entry_point Python script within a SageMaker Training Job.

Training is started by calling fit() on this Estimator.

Parameters
  • py_version (str) – Python version you want to use for executing your model training code. Defaults to None. Required unless image_uri is provided. If using PyTorch, the current supported version is py36. If using TensorFlow, the current supported version is py37.

  • entry_point (str) – Path (absolute or relative) to the Python source file which should be executed as the entry point to training. If source_dir is specified, then entry_point must point to a file located at the root of source_dir.

  • transformers_version (str) – Transformers version you want to use for executing your model training code. Defaults to None. Required unless image_uri is provided. The current supported version is 4.6.1.

  • tensorflow_version (str) – TensorFlow version you want to use for executing your model training code. Defaults to None. Required unless pytorch_version is provided. The current supported version is 2.4.1.

  • pytorch_version (str) – PyTorch version you want to use for executing your model training code. Defaults to None. Required unless tensorflow_version is provided. The current supported versions are 1.7.1 and 1.6.0.

  • source_dir (str) – Path (absolute, relative or an S3 URI) to a directory with any other training source code dependencies aside from the entry point file (default: None). If source_dir is an S3 URI, it must point to a tar.gz file. Structure within this directory are preserved when training on Amazon SageMaker.

  • hyperparameters (dict) – Hyperparameters that will be used for training (default: None). The hyperparameters are made accessible as a dict[str, str] to the training code on SageMaker. For convenience, this accepts other types for keys and values, but str() will be called to convert them before training.

  • image_uri (str) –

    If specified, the estimator will use this image for training and hosting, instead of selecting the appropriate SageMaker official image based on framework_version and py_version. It can be an ECR url or dockerhub image and tag. .. rubric:: Examples

    • 123412341234.dkr.ecr.us-west-2.amazonaws.com/my-custom-image:1.0

    • custom-image:latest

    If framework_version or py_version are None, then image_uri is required. If also None, then a ValueError will be raised.

  • distribution (dict) –

    A dictionary with information on how to run distributed training (default: None). Currently, the following are supported: distributed training with parameter servers, SageMaker Distributed (SMD) Data and Model Parallelism, and MPI. SMD Model Parallelism can only be used with MPI. To enable parameter server use the following setup:

    {
        "parameter_server": {
            "enabled": True
        }
    }
    

    To enable MPI:

    {
        "mpi": {
            "enabled": True
        }
    }
    

    To enable SMDistributed Data Parallel or Model Parallel:

    {
        "smdistributed": {
            "dataparallel": {
                "enabled": True
            },
            "modelparallel": {
                "enabled": True,
                "parameters": {}
            }
        }
    }

Hugging Face Training Compiler Configuration

class sagemaker.huggingface.TrainingCompilerConfig(enabled=True, debug=False)

Bases: object

The configuration class for accelerating SageMaker training jobs through compilation.

SageMaker Training Compiler speeds up training by optimizing the model execution graph.

This class initializes a TrainingCompilerConfig instance.

Pass the output of it to the compiler_config parameter of the HuggingFace class.

Parameters
  • enabled (bool) – Optional. Switch to enable SageMaker Training Compiler. The default is True.

  • debug (bool) – Optional. Whether to dump detailed logs for debugging. This comes with a potential performance slowdown. The default is False.

Example: The following example shows the basic compiler_config parameter configuration, enabling compilation with default parameter values.

from sagemaker.huggingface import TrainingCompilerConfig
compiler_config = TrainingCompilerConfig()
DEBUG_PATH = '/opt/ml/output/data/compiler/'
SUPPORTED_INSTANCE_CLASS_PREFIXES = ['p3', 'g4dn', 'p4']
HP_ENABLE_COMPILER = 'sagemaker_training_compiler_enabled'
HP_ENABLE_DEBUG = 'sagemaker_training_compiler_debug_mode'
disclaimers_and_warnings()

Disclaimers and warnings.

Logs disclaimers and warnings about the requested configuration of SageMaker Training Compiler.

classmethod validate(image_uri, instance_type, distribution)

Checks if SageMaker Training Compiler is configured correctly.

Parameters
  • image_uri (str) – A string of a Docker image URI that’s specified to HuggingFace. If SageMaker Training Compiler is enabled, the HuggingFace estimator automatically chooses the right image URI. You cannot specify and override the image URI.

  • instance_type (str) – A string of the training instance type that’s specified to HuggingFace. The validate classmethod raises error if an instance type not in the SUPPORTED_INSTANCE_CLASS_PREFIXES list or local is passed to the instance_type parameter.

Raises

ValueError – Raised if the requested configuration is not compatible with SageMaker Training Compiler.
