Are you training the network with different data at each epoch? #234

Hi, thank you for your work! I am implementing the network with custom data and I am struggling in the dataloading. I tried cutting squares but I ended up with different input sizes and forced to keep batch =1. I want to cut and save the input files as samples before the training - I have very huge point clouds and very sparse in some regions - so I was thinking on a strategy to have consistent, fixed size inputs.

Looking at the code here I was wandering if:

  1. At each epoch the picked index is different so the training data are inconsistent between epochs or are you avoiding this effect with a manual seed?
  2. How can you be sure that you are covering the whole point clouds in training phase?
