Channel

class aws_cdk.aws_stepfunctions_tasks.Channel(*, channel_name, data_source, compression_type=None, content_type=None, input_mode=None, record_wrapper_type=None, shuffle_config=None)

Bases: object

__init__(*, channel_name, data_source, compression_type=None, content_type=None, input_mode=None, record_wrapper_type=None, shuffle_config=None)

Describes the training, validation or test dataset and the Amazon S3 location where it is stored.

Parameters

• channel_name (str) – Name of the channel.

• data_source (DataSource) – Location of the channel data.

• compression_type (Optional[CompressionType]) – Compression type if training data is compressed. Default: - None

• content_type (Optional[str]) – The MIME type of the data. Default: - None

• input_mode (Optional[InputMode]) – Input mode to use for the data channel in a training job. Default: - None

• record_wrapper_type (Optional[RecordWrapperType]) – Specify RecordIO as the value when input data is in raw format but the training algorithm requires the RecordIO format. In this case, Amazon SageMaker wraps each individual S3 object in a RecordIO record. If the input data is already in RecordIO format, you don’t need to set this attribute. Default: - None

• shuffle_config (Optional[ShuffleConfig]) – Shuffle config option for input data in a channel. Default: - None
