ConnectionResetError: [Errno 104] Connection reset by peer下载数据集的代码如下:
代码语言：javascript复制from sklearn.datasets import fetch_mldata
mnist = fetch_mldata('MNIST original')
mnist解决方案
下载mnist-original.mat并且保存到 ~/scikit_learn_data/mldata/(scikit data home dir)下面即可
查找scikit data home dir 的代码:
代码语言：javascript复制from sklearn.datasets.base import get_data_home
print (get_data_home())
