This pipeline generates an image based on a previous image input. Example: ```python >>> from PIL import Image >>> import requests >>> from transformers import pipeline >>> upscaler = pipeline("image-to-image", model="caidas/swin2SR-classical-sr-x2-64") >>> img = Image.open(requests.get("http://images.cocodataset.org/val2017/000000039769.jpg", stream=True).raw) >>> img = img.resize((64, 64)) >>> upscaled_img = upscaler(img) >>> img.size (64, 64) >>> upscaled_img.size (144, 144) ``` This image to image pipeline can currently be loaded from [`pipeline`] using the following task identifier: `"image-to-image"`.

Args: images (`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. timeout (`float`, *optional*, defaults to None): The maximum time in seconds to wait for fetching images from the web. If None, no timeout is used and the call may block forever. Return: An image (Image.Image) or a list of images (List["Image.Image"]) containing result(s). If the input is a single image, the return will be also a single image, if the input is a list of several images, it will return a list of transformed images. )r__call__)rr'rrs rr*zImageToImagePipeline.__call__Ws4w1&11rc*|jdi|}|S)Nr")model)r model_inputs model_outputss r_forwardzImageToImagePipeline._forwardss" 2\2 rct||}|j|gd}|jdk(r|j|j}|S)N)r pt)r'return_tensors)rimage_processor frameworkto torch_dtype)rimager inputss r preprocesszImageToImagePipeline.preprocesswsJ5'2%%eWT%J >>T !YYt//0F rcg}d|jvr |j}D]}|jjj j j ddj}tj|dd}|dzjjtj}|jtj|t!|dkDr|S|dS)Nreconstructionrr )source destinationgo@)keysr;datasqueezefloatcpuclamp_numpynpmoveaxisroundastypeuint8appendr fromarraylen)rr.r'outputsoutputs r postprocessz ImageToImagePipeline.postprocess~s }113 3#22G 3F[[((*002668??1EKKMF[[rBFun++-44RXX>F MM%//&1 2  3 Vqv7fQi7r)N)__name__ __module__ __qualname____doc__rr&rstrrr*r/r9rP __classcell__)rs@rrr's^:F E2CcM4 ;NNO2 }d=11 228 8rr)typingrrrErFutilsrrrr r baser r PILr image_utilsrmodels.auto.modeling_autor get_loggerrQloggerrr"rrr_so5(R   H %,FG`88`8H`8r
