卷积神经网络有报错

飘香一剑

from tensorflow.examples.tutorials.mnist import input_data
mnist = input_data.read_data_sets(".", one_hot=True)
输入这个就有报错，不知道什么意思？哪位大佬知道。

只是警告而已，没关系的。版本迭代read_data_sets这个函数以后就没了而已（比如你升级tf版本之后），现在还是能用的。

不行啊，满屏报错，后面还有

这些全部是报错

你把数据集下载下来放在当前目录就行了。别用代码下。

飘香一剑

试过了，但是我也不知道代码哪一段是下载数据的。是不是要把那一段删除，反正就是第二行开始报错的，不知道怎么改代码
