CVNets: A library for training computer vision networks

CVNets is a computer vision toolkit that allows researchers and engineers to train standard and novel mobile- and non-mobile computer vision models for variety of tasks, including object classification, object detection, semantic segmentation, and foundation models (e.g., CLIP).

What's new?

• July 2023: Version 0.4 of the CVNets library includes
  • Bytes Are All You Need: Transformers Operating Directly On File Bytes
  • RangeAugment: Efficient online augmentation with Range Learning
  • Training and evaluating foundation models (CLIP)
  • Mask R-CNN
  • EfficientNet, Swin Transformer, and ViT
  • Enhanced distillation support

Installation

We recommend to use Python 3.10+ and PyTorch (version >= v1.12.0)

Instructions below use Conda, if you don't have Conda installed, you can check out How to Install Conda.

# Clone the repo
git clone git@github.com:apple/ml-cvnets.git
cd ml-cvnets

# Create a virtual env. We use Conda
conda create -n cvnets python=3.10.8
conda activate cvnets

# install requirements and CVNets package
pip install -r requirements.txt -c constraints.txt
pip install --editable .
