在Pytorch中,一般通过DataLoader来完成数据的批量导入,而如果想将数据载入DataLoader,则需要继承Dataset类并实现自己的数据集。 数据集的实现和关键代码的注释如下:class MRIDataset(Dataset): def __init__(self, url, transform=None): self.imgs = glob.glob(os.path.join(url, 'img/*.jpg')) ...

这里我们使用monai.data.Dataset加载之前定义的训练和验证字典,并对输入数据应用相应的转换。dataloader用于将数据集加载到内存中。我们将为训练和验证以及每个视图定义一个数据集和数据加载器。 为了方便演示,我们使用通过使用torch.utils.data.Subset,在指定的索引处创建一个子集,只是用部分数据训练加快演示速度。 代码...
