CVNets: A library for training computer vision networks

This repository contains the source code for training computer vision models. Specifically, it contains the source code of the MobileViT paper for the following tasks:

• Image classification on the ImageNet dataset
• Object detection using SSD
• Semantic segmentation using Deeplabv3

Note: Any image classification backbone can be used with object detection and semantic segmentation models

Training can be done with two samplers:

• Standard distributed sampler
• Mulit-scale distributed sampler

We recommend to use multi-scale sampler as it improves generalization capability and leads to better performance. See MobileViT for details.

Installation

CVNets can be installed in the local python environment using the below command:

    git clone git@github.com:apple/ml-cvnets.git
    cd ml-cvnets
    pip install -r requirements.txt
    pip install --editable .

We recommend to use Python 3.6+ and PyTorch (version >= v1.8.0) with conda environment. For setting-up python environment with conda, see here.

Getting Started

• General instructions for training and evaluation different models are given here.
• Examples for a training and evaluating a specific model are provided in the examples folder. Right now, we support following models.
  • MobileViT
  • MobileNetv2
  • ResNet
• For converting PyTorch models to CoreML, see README-pytorch-to-coreml.md.
