Memory size isn't big enough

[LLUVV]

Hey ,

first I want to thank you for providing this extraordinary framework , it helps a lot.

The thing I want to ask is about insufficient memory. I'm working on a dataset involve 400 graphs each with 128 nodes. I use a 16G memory PC to run it and got killed because of insufficient memory. I check the code and found out that the process of constructing .npz of adjency matrix would use so much memory. I'm wondering were you encountered same problems and how did you solve it? I've google the question, and tkipf have responded similar question and suggested to solve it with mini batch training, want to know that have you tried it or not and how can it be executed with your code.

I'd be glad to hear from you soon. Thanks a lot!
