直接写: mnist.load_data("F:mnist.npz") AI代码助手复制代码 即可~ 补充:解决Keras下,imdb.load_data(num_words=10000)无法下载数据集的问题 当我们按照deeplearning with python书里面的代码教程来时,往往会出现数据集下载失败的问题, 例如运行下面一段代码 (train_data, train_labels), (test_data, test_l...
(1)自己下载cifar-10-python.tar.gz,然后将文件放到对应路径(～./keras/datasets/); (2)将文件夹名称cifar-10-python.tar.gz改为cifar-10-batches-py.tar.gz。 这两步操作综合,在所下载文件cifar-10-python.tar.gz的根目录下,使用如下命令: cpcifar-10-python.tar.gz ～./keras/datasets/cifar-10-batch...
