property num_per_epoch(self)

property __getitem__(self, i)

__len__(self)

_init_available_splits(self)

Initializing available splits dictionary depending on what kind of splits the dataset has.

abstract _validate_feature_structure(self)

Checking if the given dataset has a valid feature structure.

This method will raise a ValueError if the structure is invalid.

Args:

Returns:

abstract _format_dataset(self)

Converting the format of loaded dataset.

class blueoil.datasets.tfds.TFDSClassification(name, data_dir, image_size, download=False, local_rank=None, num_max_boxes=None, tfds_pre_processor=None, tfds_augmentor=None, *args, **kwargs)

Bases: blueoil.datasets.tfds.TFDSMixin, blueoil.datasets.base.Base

A dataset class for loading TensorFlow Datasets for classification. TensorFlow Datasets which have “label” and “image” features can be loaded by this class.

property classes(self)

Return the classes list in the data set.

property num_classes(self)

Return the number of classes in the data set.

_validate_feature_structure(self)

Checking if the given dataset has a valid feature structure.

This method will raise a ValueError if the structure is invalid.

Args:

Returns:

_format_dataset(self)

Converting the format of loaded dataset.

class blueoil.datasets.tfds.TFDSObjectDetection(name, data_dir, image_size, download=False, local_rank=None, num_max_boxes=None, tfds_pre_processor=None, tfds_augmentor=None, *args, **kwargs)

Bases: blueoil.datasets.tfds.TFDSMixin, blueoil.datasets.base.ObjectDetectionBase

A dataset class for loading TensorFlow Datasets for object detection. TensorFlow Datasets which have “objects” and “image” features can be loaded by this class.
