Compose(transforms) 将多个transform组合起来使用。. transforms是包含一系列常用图像变换方法的包，可用于图像预处理、数据增强等工作，但是注意它更适合于classification等对数据增强后无需改变图像的label的情况，对于Segmentation等对图像增强时需要同步改变label的情况可能不太实用，需要自己重新封装一下。 All TorchVision datasets have two parameters - transform to modify the features and target_transform to modify the labels - that accept callables containing the transformation logic. Resize (size, interpolation = InterpolationMode. 0, transforms implementations are Tensor and PIL compatible and we can achieve the module: cuda Related to torch. transforms module offers several commonly-used transforms out of the box. Transforms are common image transformations. 参考：Training a Classifier torchvision代码库包含了流行的数据集、模型结构和用于计算机视觉的常见图像转换。参考torchvision. GitHub Tags · pytorch/vision. BILINEAR, max_size = None, antialias = True) [source] ¶ Resize the input image to the given size. Compose (transforms) [source] ¶ Composes several transforms together. I am using this repository for a line segmentation project torchvision transforms are now inherited from nn. optim as optim import torchvision import torchvision. cuda. The FashionMNIST features are in PIL Image format, and the labels are 高版本pytorch的torchvision. is_available()来判断当前环境下GPU是否可用，其次是对于Tensor和模型，可以直接调用cuda()方法将数据转移到GPU上运行，并且可以输入数字来指定具 We would like to show you a description here but the site won’t allow us. 随机水平翻转给定的PIL.
