    Depth estimation pipeline using any `AutoModelForDepthEstimation`. This pipeline predicts the depth of an image.

    Example:

    ```python
    >>> from transformers import pipeline

    >>> depth_estimator = pipeline(task="depth-estimation", model="LiheYoung/depth-anything-base-hf")
    >>> output = depth_estimator("http://images.cocodataset.org/val2017/000000039769.jpg")
    >>> # This is a tensor with the values being the depth expressed in meters for each pixel
    >>> output["predicted_depth"].shape
    torch.Size([1, 384, 384])
    ```

    Learn more about the basics of using a pipeline in the [pipeline tutorial](../pipeline_tutorial)


    This depth estimation pipeline can currently be loaded from [`pipeline`] using the following task identifier:
    `"depth-estimation"`.

    See the list of available models on [huggingface.co/models](https://huggingface.co/models?filter=depth-estimation).

        Predict the depth(s) of the image(s) passed as inputs.

        Args:
            inputs (`str`, `List[str]`, `PIL.Image` or `List[PIL.Image]`):
                The pipeline handles three types of images:

                - A string containing a http link pointing to an image
                - A string containing a local path to an image
                - An image loaded in PIL directly

                The pipeline accepts either a single image or a batch of images, which must then be passed as a string.
                Images in a batch must all be in the same format: all as http links, all as local paths, or all as PIL
                images.
            parameters (`Dict`, *optional*):
                A dictionary of argument names to parameter values, to control pipeline behaviour.
                The only parameter available right now is `timeout`, which is the length of time, in seconds,
                that the pipeline should wait before giving up on trying to download an image.
            timeout (`float`, *optional*, defaults to None):
                The maximum time in seconds to wait for fetching images from the web. If None, no timeout is set and
                the call may block forever.

        Return:
            A dictionary or a list of dictionaries containing result. If the input is a single image, will return a
            dictionary, if the input is a list of several images, will return a list of dictionaries corresponding to
            the images.

            The dictionaries contain the following keys:

            - **predicted_depth** (`torch.Tensor`) -- The predicted depth by the model as a `torch.Tensor`.
            - **depth** (`PIL.Image`) -- The predicted depth by the model as a `PIL.Image`.
