My pytorch code doesn't seem to work

Python Help

import torch
import torchvision
from torch.utils.data import Dataset, DataLoader
import numpy as np
import math


class WineDataset(Dataset):

    def __init__(self):
        # data load
        xy = np.loadtxt('wine.csv', delimiter=',', dtype=np.float32, skiprows=1)
        self.x = torch.from_numpy(xy[:, 1:])
        self.y = torch.from_numpy(xy[:, [0]])  # n_samples, 1
        self.n_samples = xy.shape[0]

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

    def __len__(self):
        return self.n_samples


dataset = WineDataset()
dataloader = DataLoader(dataset=dataset, batch_size=4, shuffle=True, num_workers=2)

dataiter = iter(dataloader)
data = dataiter.next()
features, labels = data
print(features, labels)

When I do this, this just gets the message that dataiter doesn’t have .next() what can I do to mediate this?

Have you tried next(dataiter)?

yes, thank you!
