Training loss visualization

We use Wandb to visualize losses during training. You are welcome to roll your own visualization, just comment out the lines involving wandb.

Docker

To write to files in the mounted volume, make an "out" folder with permissions 777.

We need cuda10 to visualize. cuda11 to run on 3090 gtx cards.

Processing depth camera in sim

  1. Get raw, large pointcloud from pybullet cameras
  2. Voxel-based downsampling
  3. Uniform downsampling to 2048 (we can handle variable sized pointclouds, but this is done to ensure we stay within the computational limits)

Debugging issues

  • If get_bti_from_rotated fails increase max_frac_threshold, we might just not be finding enough points
