您好，首先四维张量的第一维是数据组数，即是将所有的batch并在了一起；第二维是output_window也就是未来时间步长，您可以根据您的具体需要在./ibcity/traffic_state_executor.py中evaluate函数（268行）处添加处理数据的代码，也可以直接根据需要处理这个npz文件

谢谢回复，因为npz文件中不包含站点id和时间戳信息，因此输出的值是难以识别对应“时空”信息的，请问如何处理这个问题？此外对于上述提出的第一个问题，是否可以提供一些代码demo以供学习如何处理张量数据。谢谢你的帮助和解答

此外，输出npz文件中期望获得的是测试集预测值和真实值，这是包含全部batch size和时间步长吗？当前数据结构和期望获得数据格式关系是怎样的或者是如何转换的？希望得到您的解答
