Remedy Self-supervised Learning on Lightweight Models with Distilled Contrastive Learning

Pytorch Implementation for DisCo: Remedy Self-supervised Learning on Lightweight Models with Distilled Contrastive Learning

Requirements

  • Python3
  • Pytorch 1.6+
  • Detectron2
  • 8 GPUs are preferred
  • ImageNet, Cifar10/100, VOC, COCO

Run

Before running, we firstly move all data into share memory

cp /path/to/ImageNet /dev/shm

BI Analysis

code for BI is put on data

Checkpoints

TO BE Releasese...

Architecture Self-supervised Methods Model Checkpoints
ResNet152 MoCo-V2 Model
ResNet101 MoCo-V2 Model
ResNet50 MoCo-V2 Model

For teacher models such as ResNet-50*2 etc, we use their official implementation, which can be downloaded from their github pages.

Recommendation Operations

If memory of your machine is big enough to hold the whole datasets, I strongly encourage you to put that into memory, which can dramatically save IO time and speed up the programe.

cp /path/to/dataset /dev/shm

Thanks

Code heavily depends on MoCo-V2, Detectron2.
