Works with binary target data. Accepts float predictions from a model output. As input to ``forward`` and ``update`` the metric accepts the following input: - ``preds`` (:class:`~torch.Tensor`): A float tensor of shape ``(N, ...)`` - ``target`` (:class:`~torch.Tensor`): A long or bool tensor of shape ``(N, ...)`` - ``indexes`` (:class:`~torch.Tensor`): A long tensor of shape ``(N, ...)`` which indicate to which query a prediction belongs As output to ``forward`` and ``compute`` the metric returns the following output: - ``p@k`` (:class:`~torch.Tensor`): A single-value tensor with the precision (at ``top_k``) of the predictions ``preds`` w.r.t. the labels ``target`` All ``indexes``, ``preds`` and ``target`` must have the same dimension and will be flatten at the beginning, so that for example, a tensor of shape ``(N, M)`` is treated as ``(N * M, )``. Predictions will be first grouped by ``indexes`` and then will be computed as the mean of the metric over each query. Args: empty_target_action: Specify what to do with queries that do not have at least a positive ``target``. Choose from: - ``'neg'``: those queries count as ``0.0`` (default) - ``'pos'``: those queries count as ``1.0`` - ``'skip'``: skip those queries; if all queries are skipped, ``0.0`` is returned - ``'error'``: raise a ``ValueError`` ignore_index: Ignore predictions where the target is equal to this number. top_k: Consider only the top k elements for each query (default: ``None``, which considers them all) adaptive_k: Adjust ``top_k`` to ``min(k, number of documents)`` for each query kwargs: Additional keyword arguments, see :ref:`Metric kwargs` for more info. Raises: ValueError: If ``empty_target_action`` is not one of ``error``, ``skip``, ``neg`` or ``pos``. ValueError: If ``ignore_index`` is not `None` or an integer. ValueError: If ``top_k`` is not ``None`` or not an integer greater than 0. ValueError: If ``adaptive_k`` is not boolean. Example: >>> from torch import tensor >>> from torchmetrics.retrieval import RetrievalPrecision >>> indexes = tensor([0, 0, 0, 1, 1, 1, 1]) >>> preds = tensor([0.2, 0.3, 0.5, 0.1, 0.3, 0.5, 0.2]) >>> target = tensor([False, False, True, False, True, False, True]) >>> p2 = RetrievalPrecision(top_k=2) >>> p2(preds, target, indexes=indexes) tensor(0.5000) Fis_differentiableThigher_is_betterfull_state_updategplot_lower_boundg?plot_upper_boundnegN)empty_target_action ignore_indextop_k adaptive_kkwargsreturnc s\tjf||d||dur:t|tr2|dks:tdt|tsLtd||_||_dS)N)rrrz,`top_k` has to be a positive integer or Nonez `adaptive_k` has to be a boolean)super__init__ isinstanceint ValueErrorboolrr)selfrrrrr __class__i/var/www/html/stable-diffusion-webui/venv/lib/python3.9/site-packages/torchmetrics/retrieval/precision.pyrZs zRetrievalPrecision.__init__)predstargetrcCst|||j|jdS)N)rr)rrr)r r%r&r#r#r$_metricoszRetrievalPrecision._metric)valaxrcCs |||S)acPlot a single or multiple values from the metric.
