Sampler to sample contiguous data?

2

Do you want overlapping windows or unique ones?
If overlapping is OK, you could just use the shuffled indices and slice your data.
Otherwise you could use something like this:

class MyDataset(Dataset):
    def __init__(self, window=10):
        self.data = torch.arange(100).view(-1, 1).expand(-1, 10)
        self.window = window
        
    def __getitem__(self, index):
        index = index * self.window
        x = self.data[index:index+self.window]
        return x
    
    def __len__(self):
        return len(self.data) / self.window

dataset = MyDataset(window=10)
print(dataset[0])
