Question

这是我的代码

import tensorflow as tf
from tensorflow import keras
import numpy as np
import matplotlib.pyplot as plt

data = keras.datasets.fashion_mnist

(train_images, train_labels), (test_images, test_labels) = data.load_data()

这给了我一个很长的可怕错误：

我真的很陌生，所以真的迷路了...

这可能是因为您没有安装python证书，这在Mac上是很常见的错误。只要进入安装Python的任何位置，然后双击“ Install Certificates.command”文件，就可以解决该问题。

在此处检查此链接： Mac OSX python ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749)

为什么加载数据集“ .load_data（）”时python失败
