Question on the num_feat for ENZYMES dataset

[lizaitang]

Dear Author, your code really helps a lot. I have a question that seems that node_feature in original dataset is 18, while in the mat you provided is 21, how do you transfer it?

Thanks for your attention to our paper and code bases. The extra 3 features are the one-hot coding of node type. As it can be seen on the table 4 in the paper (https://arxiv.org/pdf/2003.11702.pdf) there are 18 continuous features and 3 type of nodes. So we encode node type as a categorical features of the nodes. Hope this explanation works for you.

Thank you so much，so where should we add the one hot vector? right after the 18 features？
