question about the data?

[MrCrazyCrab]

could you please tell me what the meaning of "pos, norm, batch = data.pos, data.norm, data.batch" is ? what 's the shape of pos,nor and batch? i can figure out the pos means the position, the norm is the normal data, what about batch?

It is the indexes of the points, which follows PYG, you may refer to the documentation of PYG. The shape of the batch is B*N, like [000...111...222...].
