Get Started

Environment

  • Ubuntu 16.04 / 18.04
  • Pytorch 1.3.1
  • CUDA 10
  • conda > 4.6.2

Using Anaconda to install all dependences.

conda env create -f environment.yml

Train

CUDA_VISIBLE_DEVICES=<gpus> python train.py --options <config>

Predict

CUDA_VISIBLE_DEVICES=<gpus> python predictor.py --options <config>

Evaluation [WIP]

Custom guide

  • custom scheduler for training/inference loop, add code in scheduler and inherit base class.
  • custom model in models/zoo
  • custom config options in utils/config
  • custom dataset in datasets/data

External

  • Chamfer Distance
