运行我的代码时，我收到此错误消息“ RuntimeError：DataLoader worker (pid(s) 48817, 48818) 意外退出” 我完全不确定从哪里开始解决此问题。任何指导都将不胜感激。下面发布了代码和回溯

batch_size = 128
image_size = (64,64)
stats = (0.5, 0.5, 0.5), (0.5, 0.5, 0.5)

transform_ds = transforms.Compose([transforms.Resize(image_size),
#                                    transforms.RandomCrop(32, padding=2),
#                                    transforms.RandomHorizontalFlip(),
                                   transforms.ToTensor(),
                                   transforms.Normalize(*stats)
                                   ])

train_ds = facesDataset(csv_file = 'imagesdataset.csv', root_dir = 'images', 
                      transform = transform_ds)

train_dl = DataLoader(train_ds, batch_size, shuffle=True, num_workers=3, pin_memory=True)
print(len(train_ds))

def denorm(img_tensors):
    return img_tensors * stats[1][0] + stats[0][0]

def show_images(img, nmax=64):
    fig, ax = plt.subplots(figsize=(8, 8))
    ax.set_xticks([]); ax.set_yticks([])
    ax.imshow(make_grid(denorm(img.detach()[:nmax]), nrow=8).permute(1, 2, 0))
