Returns an instance of DetectionMetrics initialized for the LVIS dataset.

  • save_folder – path to the folder where to write model output files. Defaults to None, which means that the model output of test instances will not be stored.

  • filename_prefix – prefix common to all model outputs files. Ignored if save_folder is None. Defaults to “model_output”

  • iou_types – list of (or a single string) strings describing the iou types to use when computing metrics. Defaults to “bbox”. Valid values are “bbox” and “segm”.

  • summarize_to_stdout – if True, a summary of evaluation metrics will be printed to stdout (as a table) using the Lvis API. Defaults to True.

  • evaluator_factory – Defaults to LvisEvaluator constructor.

  • gt_api_def – Defaults to the list of supported datasets (LVIS is supported in Avalanche through class:LvisDataset).


A metric plugin that can compute metrics on the LVIS dataset.
