I create a simple dataset that has two CUDA tensors, one of shape (1000, 5) and the other (1000,) but when I load them using a DataLoader only the first one is returned as CUDA tensor. I think this may have something to do with the default collate_fn of the DataLoader. Any fixes ?
import torch
from torch.utils.data import Dataset, DataLoader
import numpy as np

x = torch.cuda.FloatTensor(np.random.randn(1000, 5))
y = torch.cuda.LongTensor(np.random.randint(0,10, size=(1000, )))

class data(Dataset):
    def __init__(self, inputs, targets):
        self.x = inputs
        self.y = targets

    def __len__(self):
        return self.x.size()[0]

    def __getitem__(self, idx):
         return (self.x[idx], self.y[idx])

d = data(x, y)
dl = DataLoader(d, batch_size=5)

for item in dl:
    print(item)
    break

Output
