Dataset not found. You can use download=True to download it

This error message usually occurs when you are trying to load a dataset in your code, but the dataset is not available in your local directory or it has not been downloaded yet. To fix this error, you can add the argument `download=True` when loading the dataset. This will automatically download the dataset if it is not available in your local directory. For example, if you are using the PyTorch library, you can download the CIFAR-10 dataset using the following code:

import torch
import torchvision.datasets as datasets

train_dataset = datasets.CIFAR10(root='./data', train=True, download=True)
test_dataset = datasets.CIFAR10(root='./data', train=False, download=True)

This code will download the CIFAR-10 dataset and store it in a `data` folder in your current working directory.
