Member Function Documentation

def caffe2.python.cached_reader.CachedReader.build_cache_step	(		self,
			overwrite = False
	)

Build a step for generating cache DB file.

    If self.db_path exists and not overwritting, build an empty step.
    Overwise, build a step as follows.
    Pipe original reader to the _DatasetWriter,
    so that dataset field blobs are populated.
    Then save these blobs into a file.

    Args:
overwrite: bool. If true, ignore the existing file
    and build a new one overwritting the existing one anyway.

    Returns:
build_cache_step: ExcutionStep.
    The step to be run for building a cache DB file.
