Reload saved view

[brimoor]

Adds a @voxel51/utils/reload_saved_view operator that allows the user to trigger a reload() of a generated view (patches, frames, clips).

On fiftyone>=1.0.0, the operator inspects the last_modified_at times of the view and dataset's samples to attempt to provide guidance on whether the view is up-to-date.

Note that, in the example below, the App is not able to conclusively discern that patches is outdated after sample deletion as deletion does not increase any last_modified_at value. This would require further core SDK enhancement in fiftyone>1.0.0.

Example usage

import fiftyone as fo
import fiftyone.zoo as foz

dataset = foz.load_zoo_dataset("quickstart")

limit = dataset.limit(100)
patches = dataset.to_patches("ground_truth")

dataset.save_view("limit", limit)
dataset.save_view("patches", patches)

session = fo.launch_app(patches)

dataset.delete_samples(dataset[:50])

# Use reload_saved_view to reload 'patches' view in the App
