why is network architecture different from original?

Hi Shaoshaui,

Regarding the network architecture in your pytorch implementation. I noticed that in the SA and FP modules, the mlp / conv2d channel input and output dimensions differ from the dimensions used in the 'official' PointNet++ code by Charles Qi. Additionally, per SA layer, there are two SharedMLP's instead of one, as in Charles' code.

What are the reasons for the differences?

Thank you! Tam
