ultralytics.models.fastsam.val.FastSAMValidator

FastSAMValidator(
    dataloader=None, save_dir=None, pbar=None, args=None, _callbacks=None
)

Bases: SegmentationValidator

Custom validation class for fast SAM (Segment Anything Model) segmentation in Ultralytics YOLO framework.

Extends the SegmentationValidator class, customizing the validation process specifically for fast SAM. This class sets the task to 'segment' and uses the SegmentMetrics for evaluation. Additionally, plotting features are disabled to avoid errors during validation.

Attributes:

Name	Type	Description
`dataloader`		The data loader object used for validation.
`save_dir`	`str`	The directory where validation results will be saved.
`pbar`	`str`	A progress bar object.
`args`	`str`	Additional arguments for customization.
`_callbacks`	`str`	List of callback functions to be invoked during validation.

Parameters:

Name	Type	Description	Default
`dataloader`	`DataLoader`	Dataloader to be used for validation.	`None`
`save_dir`	`Path`	Directory to save results.	`None`
`pbar`	`tqdm`	Progress bar for displaying progress.	`None`
`args`	`SimpleNamespace`	Configuration for the validator.	`None`
`_callbacks`	`dict`	Dictionary to store various callback functions.	`None`

Notes

Plots for ConfusionMatrix and other related metrics are disabled in this class to avoid errors.
