下载数据集时出现此错误:ValueError:对已关闭文件的I/O操作 [英] This error while downloading datasets: ValueError: I/O operation on closed file

问题描述

我已经开始与Theano和Keras进行深度学习.但是，对于任何程序，我都必须加载数据集，而我却无法加载任何数据集.

I have started with deep learning with Theano and Keras. However, for any program, I will have to load the dataset, and i'm not able to load any dataset.

即使我运行这两行:-

from keras.datasets import cifar10
(X_train, y_train), (X_test, y_test) = cifar10.load_data()

我什至用最小的数据集尝试了上述方法.完全一样的错误.

I even tried the above with minst dataset. Exact same error.

我试图一个一个地运行命令，第一次导入进展顺利.在第二个命令中，它运行并开始下载python. 但是，几秒钟后，它破裂了.

I tried to run the commands one by one, the first import goes well. In the second command, it runs and python begins downloading. However, after a few seconds, it breaks.

这是确切的错误:-

我不知道为什么会这样.似乎文件data_utils.py

I do not know why this is happening. Seems like something is wrong in the file data_utils.py

我该怎么办?

推荐答案

我尝试了您的确切代码，并且在我的计算机上可以正常工作.失败可能是由于多种原因造成的，例如互联网连接不稳定或主文件夹中的可用空间不足.

I tried your exact code and it works fine on my computer. The failure could be due to several reasons, like a unstable internet connection or not enough free space in your home folder.

您可以做的是下载文件使用下载管理器手动将其放入〜/.keras/datasets中，并将其重命名为cifar-10-batches-py.tar.gz并再次运行代码，它应该提取文件并从那里继续进行处理.

What you can do is to download the file manually using a download manager, put it in ~/.keras/datasets and rename it to cifar-10-batches-py.tar.gz and run the code again, it should pick up the file and continue processing from there.
