How to evaluate your model on another dynamic graph dataset?

[Uchman21]

I have a simple dataset of temporal graphs and would like to train it for link prediction. So far going through your code, everything seems confusing and highly tailored for only the social evolution dataset and not so clear to tailor for others. Can you provide a simple data loader for other normal graph datasets?

PS: A large amount of console printouts makes running the code confusing

Hi,
Thanks for reporting this. I hope to have time in the future to fix this issue, but not sure when. So PRs are welcome.

On high level, the code should work with any data loader that returns (u, v, time_delta_uv, k, time_bar, time_cur) for each event:
https://github.com/uoguelph-mlrg/LDG/blob/master/data_loader.py#L193

where
u,v - are indices of nodes between which the event occured
time_delta_uv - is the difference between current time and previous time for nodes u and v
time_bar - are time stamps of last events for all nodes
time_cur - is current time

There can be other parts in the code where I expect the Social dataset, but only in a few places.

Hi,
I added the base data loader class and example_data_loader showing which attributes and functions should be implemented for other datasets. Plus, added another dataset, Github.
The code is still not very clean, but hope it can be useful.

Thanks! I'm just looking through your codes,
I just wonder, is there any dependencies of the version?

So, I hope, in README.md, it's good to provide the dependency and its version :)

Perhaps, it requires a set of pytorch, scikit-learn, pandas, matplotlib, etc.
