EMNIST 数据集 使用与原始 MNIST 数据集相同的二进制格式.因此，您可以从任何使用原始 MNIST 数据集的教程中获取输入管道代码，并将其指向您从下载 EMNIST 数据集获得的文件集，以在该数据集上进行训练.

The EMNIST dataset uses the same binary format as the original MNIST dataset. Therefore you can take the input pipeline code from any tutorial that uses the original MNIST dataset, and point it at the set of files you get from downloading the EMNIST dataset to train on that dataset.
