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).

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`. imagesNzECannot call the depth-estimation pipeline without an inputs argument!)pop ValueErrorrr#r"rrrr#Bs $ NcKs<i}|dur ||d<t|trd|vr|d|d<|iifS)Ntimeout) isinstancedict)rr( parametersrpreprocess_paramsrrr_sanitize_parametersls   z,DepthEstimationPipeline._sanitize_parameterscCsHt||}|j||jd}|jdkr||j}|jddd|d<|S)N)r%return_tensorspt target_size)rimage_processor frameworktodtypesize)rimager( model_inputsrrr preprocessts   z"DepthEstimationPipeline.preprocesscCs&|d}|jdi|}||d<|S)Nr1r)r&model)rr8r1 model_outputsrrr_forward|s z DepthEstimationPipeline._forwardcCs|j||dg}g}|D].}|d}||||}t|d d}| |d|dqt |dkrG|dS|S)Nr1predicted_depthuint8)r=depthr r) r2post_process_depth_estimationdetachcpunumpyminmaxr fromarrayastypeappendlen)rr;outputsformatted_outputsoutputr@rrr postprocesssz#DepthEstimationPipeline.postprocess)NNr!)__name__ __module__ __qualname____doc___load_processor_load_image_processor_load_feature_extractor_load_tokenizerrrrstrrr*r#listr-r9r<rN __classcell__rrrrrs, (0 * rN)typingrrrutilsrrrr r baser r PILr image_utilsrmodels.auto.modeling_autor get_loggerrOloggerrrrrrs
