SSL Certificate Error on VS Code while downloading Torchvision dataset
问题
尝试在VS Code中导入CIFAR10数据集时，运行代码时出现了错误。请查看下面附上的代码和输出。
from torchvision import datasets
data_path = 'dataset_cifar/'
cifar10 = datasets.CIFAR10(data_path, train=True, download=True)
cifar10_val = datasets.CIFAR10(data_path, train=False, download=True)
我收到以下错误信息：

将以下内容添加到您的代码中，以“解决”证书问题：
import ssl
ssl._create_default_https_context = ssl._create_unverified_context
英文:
add this to your code to "workaround" the certification like
import ssl
ssl._create_default_https_context = ssl._create_unverified_context
