LDA splitter：ValueError: too many values to unpack (expected 2)

[zhangtian-3841]

您好！我按照官网文档添加mnist数据集后，在使用LDA进行数据划分时，出现以下错误。您可否帮我看看这个问题呢 load_mnist:

配置文件中关于data的部分： data: root: data/ type: mnist splits: [0.6,0.2,0.2] subsample: 0.05 transform: [['ToTensor'], ['Normalize', {'mean': [0.9637], 'std': [0.1592]}]] splitter: lda splitter_args: [{'alpha': 0.1}]

出现的错误：

The data format should be list of tuples, such as [(x, y), (x, y), (x, y), ...].
