Object detection reference training scripts

This folder contains reference training scripts for object detection. They serve as a log of how to train specific models, to provide baseline training and evaluation scripts to quickly bootstrap research.

To execute the example commands below you must install the following:

cython
pycocotools
matplotlib

You must modify the following flags:

--data-path=/path/to/coco/dataset

--nproc_per_node=<number_of_gpus_available>

Except otherwise noted, all models have been trained on 8x V100 GPUs.
