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

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
