KeyError：“无法打开对象（对象'examples'不存在）”

Question

我想像emnsit一样创建HDF5ClientData实例时收到此错误。这是我的代码：

TestNIST = tff.simulation.hdf5_client_data.HDF5ClientData("mynist.hdf5")

而且我之前已经在mynist.hdf5中添加了一些数据。我不知道为什么会发生。

the instance of emnist

这是我的错误，例如：

KeyError                                  Traceback (most recent call last)
<ipython-input-169-00a78fdc8682> in <module>()
----> 1 TestNIST = tff.simulation.hdf5_client_data.HDF5ClientData("mynist.hdf5")

哦，我知道为什么会发生此错误。我再次阅读了hdf5_client_data.py的符号，发现了这一点：此类期望HDF5文件具有顶级组examples，该组包含其他子组，每个子组一个，由用户ID命名。我的高层未命名为“示例”。
