Hi, I am sorry to bother you! I have a question about temporal dataset.

In EnglandCovidDatasetLoader , X shape is (num_nodes, time_window * feature). Is that right?
I think X shape is: (num_nodes, time_window, feature) instead of (num_nodes, time_window * feature) (although feature = 1).

Each time_step should has it own graph, but in source code, it doesn't. In every time window, data share first time step graph.

Hi, I am trying to interface for the first time with this library and create a suitable dataset myself. From the JSON of the dataset, I am assuming that the graph structure is always the same and the features change at each time period. Even though the description says, "The graph indicates how many people moved from one region to the other each day", the regions in England are always the same every day; what changes is the number of people from/to.
