Constructor: PlacesDatasetImporter(dataset_dir, shuffle, seed, max_samples)
Class for importing datasets written by download_places_dataset_split`.
| Parameters | |
| dataset | the dataset directory |
| shuffle | whether to randomly shuffle the order in which the samples are imported |
| seed | a random seed to use when shuffling |
| max | a maximum number of samples to load. By default, all samples are imported |

| Method | __len__ |
The total number of samples that will be imported. |
| Method | __next__ |
Returns information about the next sample in the dataset. |
| Method | setup |
Performs any necessary setup before importing the first sample in the dataset. |
| Property | has |
Whether this importer produces a dataset info dictionary. |
| Property | has |
Whether this importer produces fiftyone.core.metadata.ImageMetadata instances for each image. |
| Property | label |
The fiftyone.core.labels.Label class(es) returned by this importer. |

| Method | close |
Performs any necessary actions after the last sample has been imported. |
| Method | get |
Returns the dataset info for the dataset. |
| Method | _preprocess |
Internal utility that preprocesses the given list---which is presumed to be a list defining the samples that should be imported---by applying the values of the shuffle, seed, and max_samples parameters of the importer. |
Returns information about the next sample in the dataset.
| Returns | |
an(image_path, image_metadata, label)tuple, where |
|
| Raises | |
StopIteration | if there are no more samples to import |
Performs any necessary setup before importing the first sample in the dataset.
This method is called when the importer's context manager interface is
entered, DatasetImporter.__enter__.
The fiftyone.core.labels.Label class(es) returned by this
importer.
This can be any of the following:
- a
fiftyone.core.labels.Labelclass. In this case, the importer is guaranteed to return labels of this type - a list or tuple of
fiftyone.core.labels.Labelclasses. In this case, the importer can produce a single label field of any of these types - a dict mapping keys to
fiftyone.core.labels.Labelclasses. In this case, the importer will return label dictionaries with keys and value-types specified by this dictionary. Not all keys need be present in the imported labels - None. In this case, the importer makes no guarantees about the labels that it may return
