[Doubt] .npz files

[mas-oliveira]

Hello, hope you're well.

First of all thank you for making your work available for the community.

I was trying to create my dataset to try your pytorch implementation. I'm having some issues generating something similar to your file adj.npz.
I was able to generate NPZs from my dataset using this repo: DCRNN Repository. But I can just have test.npz, train.npz and val.npz, and none of them looks to have some structure similar to yours.

Which way should I generate my .npz file? Do you have any idea about what I'm doing wrong?

Thanks a lot once again.
