Exports the samples and optional label field(s) to the given annotation backend.

The backend parameter controls which annotation backend to use. Depending on the backend you use, you may want/need to provide extra keyword arguments to this function for the constructor of the backend’s AnnotationBackendConfig class.

The natively provided backends and their associated config classes are:

class fiftyone.utils.annotations.AnnotationResults(samples, config, id_map, backend=None)¶

Bases: fiftyone.core.annotation.AnnotationResults

Base class for storing the intermediate results of an annotation run that has been initiated and is waiting for its results to be merged back into the FiftyOne dataset.

The id_map dictionary must record the IDs of any existing labels that are being edited by the annotation run. Any new label fields do not need to have keys in this dictionary.

For image datasets, id_map should have the following format:

{
    "<label-field>": {
        "<sample-id>": "label-id" or ["label-id", ...],
        ...
    },
    ...
}

For video datasets, id_map should have the following format:

{
    "<label-field>": {
        "<sample-id>": {
            "<frame-id>": label-id" or ["label-id", ...],
            ...
        },
        ...
    },
    ...
}

When editing scalar fields, set the dictionary values corresponding to uploaded scalars to True (since scalars do not have IDs).

If a particular sample or frame was included in the annotation run but no labels/scalars were uploaded for editing, the corresponding entry in id_map can be either missing or have a value of None.

Note

This class is serialized for storage in the database by calling serialize().

Any public attributes of this class are included in the representation generated by serialize(), so they must be JSON serializable.

Parameters

samples – a fiftyone.core.collections.SampleCollection

attributes()¶

Returns a list of class attributes to be serialized.

This method is called internally by serialize() to determine the class attributes to serialize.

Subclasses can override this method, but, by default, all attributes in vars(self) are returned, minus private attributes, i.e., those starting with “_”. The order of the attributes in this list is preserved when serializing objects, so a common pattern is for subclasses to override this method if they want their JSON files to be organized in a particular way.

Returns: a list of class attributes to be serialized

classmethod builder()¶: Returns a ConfigBuilder instance for this class.
