The pooling/aggregation section is not consistent with the paper

[Ziyang Zhang]

Hi, thanks for your work. I found, probably, a mistake on your codes.

The pooling section in gcn.py is not consistent with the Equation 4 in the 3DSSG paper. What you did is accumulating the own features based on the degree of that certain node. I demonstrated it on colab: https://colab.research.google.com/drive/1vBmdTxMfL3wKdm2mckjPZcZZVdfXTQjL?usp=sharing

And here is the official aggregation codes from Wald's cohort work (I don't know whether it is consistent with the paper either)
