Question

尝试使用以下命令加载MNIST数据时出现错误：

from sklearn.datasets import fetch_mldata
mnist = fetch_mldata('MNIST original')
mnist

我尝试删除mldata文件夹

rm -r ~/scikit_learn_data/mldata/

并根据在互联网上找到的其他答案重试了它，但它仍然无法正常工作。互联网连接或慢速连接也没有问题。上面代码中使用的命令是正确的，因为它适用于其他命令。因此，正在寻找解决方案以解决我的问题。 [注意：我正在使用Ubuntu]

错误：

任何其他解决此问题的建议将不胜感激。谢谢。
