Return type

cls

register_run(samples, key, overwrite=True)¶

Registers a run of this method under the given key on the given collection.

Parameters

overwrite (True) – whether to overwrite an existing run with the same key

classmethod save_run_results(samples, key, run_results, overwrite=True, cache=True)¶

Saves the run results on the collection.

Parameters

samples – a fiftyone.core.collections.SampleCollection
key – a run key
run_results – a RunResults, or None
overwrite (True) – whether to overwrite an existing result with the same key

The run may be invalid if, for example, a run of a different type has already been run under the same key and thus overwriting it would cause ambiguity on how to cleanup the results.

Parameters

samples – a fiftyone.core.collections.SampleCollection
key – a run key
overwrite (True) – whether to allow overwriting an existing run of the same type

Raises

ValueError – if the run is invalid

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.

samples – a fiftyone.core.collections.SampleCollection
config – an AnnotationBackendConfig
id_map – a dictionary recording the existing label IDs, in the format described above

Parameters: fields – a dictionary of pre-parsed fields
Raises: ConfigError – if some values are truth and some are not

write_json(path, pretty_print=False, **kwargs)¶

Serializes the object and writes it to disk.

Parameters

path – the output path
pretty_print – whether to render the JSON in human readable format with newlines and indentations. By default, this is False
**kwargs – optional keyword arguments for self.serialize()

fiftyone.utils.annotations.draw_labeled_images(samples, output_dir, rel_dir=None, label_fields=None, config=None, **kwargs)¶

Renders annotated versions of the images in the collection with the specified label data overlaid to the given directory.

The filenames of the sample images are maintained, unless a name conflict would occur in output_dir, in which case an index of the form "-%d" % count is appended to the base filename.

The images are written in format fo.config.default_image_ext.

Parameters

samples – a fiftyone.core.collections.SampleCollection
output_dir – the directory to write the annotated images
rel_dir (None) – an optional relative directory to strip from each input filepath to generate a unique identifier that is joined with output_dir to generate an output path for each annotated image. This argument allows for populating nested subdirectories in output_dir that match the shape of the input paths. The path is converted to an absolute path (if necessary) via fiftyone.core.utils.normalize_path()
label_fields (None) – a label field or list of label fields to render. If omitted, all compatiable fields are rendered
config (None) – an optional DrawConfig configuring how to draw the labels
**kwargs – optional keyword arguments specifying parameters of the default DrawConfig to override

Returns

the list of paths to the labeled images

fiftyone.utils.annotations.draw_labeled_image(sample, outpath, label_fields=None, config=None, **kwargs)¶

Renders an annotated version of the sample’s image with the specified label data overlaid to disk.

Parameters

sample – a fiftyone.core.sample.Sample
outpath – the path to write the annotated image
label_fields (None) – a label field or list of label fields to render. If omitted, all compatiable fields are rendered
config (None) – an optional DrawConfig configuring how to draw the labels
**kwargs – optional keyword arguments specifying parameters of the default DrawConfig to override

fiftyone.utils.annotations.draw_labeled_videos(samples, output_dir, rel_dir=None, label_fields=None, config=None, **kwargs)¶

Renders annotated versions of the videos in the collection with the specified label data overlaid to the given directory.

The filenames of the videos are maintained, unless a name conflict would occur in output_dir, in which case an index of the form "-%d" % count is appended to the base filename.

The videos are written in format fo.config.default_video_ext.

Parameters

samples – a fiftyone.core.collections.SampleCollection
output_dir – the directory to write the annotated videos
rel_dir (None) – an optional relative directory to strip from each input filepath to generate a unique identifier that is joined with output_dir to generate an output path for each annotated video. This argument allows for populating nested subdirectories in output_dir that match the shape of the input paths. The path is converted to an absolute path (if necessary) via fiftyone.core.utils.normalize_path()
label_fields (None) – a label field or list of label fields to render. If omitted, all compatiable fields are rendered
config (None) – an optional DrawConfig configuring how to draw the labels
**kwargs – optional keyword arguments specifying parameters of the default DrawConfig to override

Returns

the list of paths to the labeled videos

fiftyone.utils.annotations.draw_labeled_video(sample, outpath, support=None, label_fields=None, config=None, **kwargs)¶

Renders an annotated version of the sample’s video with the specified label data overlaid to disk.

Parameters

sample – a fiftyone.core.sample.Sample
outpath – the path to write the annotated image
support (None) – an optional [first, last] range of frames to render
label_fields (None) – a label field or list of label fields to render. If omitted, all compatiable fields are rendered
config (None) – an optional DrawConfig configuring how to draw the labels
**kwargs – optional keyword arguments specifying parameters of the default DrawConfig to override
