**Training DataLoader is Generating error by 'Tensor' object has no attribute 'deepcopy'

just encountered the same error as you, in the beginning I thought that I made a mistake but after running the colab file, I found that the error was not my fault;
If i find a solution, I will mention it here.
So far, found this: https://www.kaggle.com/questions-and-answers/391038
and that the problem occurs in the augmentable library: C:\Users\username\anaconda3\envs\torch\Lib\site-packages\imgaug\augmentables\utils.py (line 19)

Here is what i did to fix the error:

class FMNISTDataset(Dataset):
    def __init__(self, x, y, aug=None):
        self.x = x
        self.y = y
        self.aug = aug

    def __getitem__(self, ix):
        x, y = self.x[ix], self.y[ix]
        if self.aug:
            x = self.aug.augment_image(x.numpy())
        x = torch.tensor(x).unsqueeze(0).float() / 255.0
        y = torch.tensor(y).long()
        return x, y

    def __len__(self):
        return len(self.x)

Hi @andysingal

Can you post the whole code?
I tried your fix but still doesn't work, where is the collate_fn()? it was supposed to be inside the FMNISTDataset class, right?
I'd appreciate if you could help me.

I hope the issue is resolved... Thanks @Camaltra
