Does `Cheb_conv` is a sort of spectral conv?

[tomguluson92]

Hi gong! Thanks a lot for your re-implementation! But I have few question about it because I am a novice to GNN area, could you please walk me through things below?

• some papers say cheb_conv is a spectral variant of GNN model, but why the implementation of pytorch geometric's implementation inherit from MessagePassing?
• Since coMA dataset is too big for me, could you please provide very small dataset for me to train a very toy model as to have a better understand of your code?
• the minimum requirement of GPU?

Thanks a lot! Wish you all the best and stay healthy & strong! We can overcome COVID-19 !
