You can wrap your generator with a data.IterableDataset: class IterDataset (data.IterableDataset): def __init__ (self, generator): self.generator = generator def __iter__ (self): return self.generator () Naturally, you can then wrap this dataset with a data.DataLoader. Here is a minimal example showing its use: WebOne issue common in handling datasets is that the samples may not all be the same size. Most neural networks expect the images of a fixed size. Therefore, we will need to write some prepocessing code. Let’s create three transforms: Rescale: to scale the image; RandomCrop: to crop from image randomly. This is data augmentation. fishing shot conversion chart
