Witryna11 kwi 2024 · You can use functional transforms. Example of adding padding: from PIL import Image from torchvision import transforms pil_image = Image.open ("path/to/image.jpg") img_with_padding = transforms.functional.pad (pil_image, (10,10)) # Add 10px pad tensor_img = transforms.functional.to_tensor (img_with_padding) Witryna为了快速执行该示例，我们选取简单的MNIST数据，Paddle框架的 paddle.vision.datasets 包定义了MNIST数据的下载和读取。代码如下： import paddle. vision. transforms as T transform = T. Compose ( [ T. Transpose (), T. Normalize ( [ 127.5 ], [ 127.5 ])]) train_dataset = paddle. vision. datasets. MNIST ( mode="train", …
