CVNets

CVNets is a Python toolkit for training mobile and non-mobile computer-vision networks, including models for image classification, object detection, semantic segmentation and foundation-model workflows such as CLIP. It uses the PyTorch ecosystem and provides model lists, training and evaluation examples, and guidance for converting PyTorch models to CoreML.

Understand the project

Practical overview

When it fits

Use CVNets when your work involves training or evaluating computer-vision networks in a Python and PyTorch workflow and you want repository examples spanning several tasks and model families.

Who it is for

  • Researchers developing or comparing computer-vision models.
  • Engineers who need a Python toolkit for training classification, detection or segmentation networks.
  • Developers exploring mobile vision models or CLIP workflows.

Documented uses

  • Train image-classification models, including listed CNN and transformer families.
  • Train object detectors such as SSD or Mask R-CNN.
  • Train semantic-segmentation models such as DeepLabv3 or PSPNet.
  • Explore augmentation and distillation techniques in model-training workflows.
  • Use the provided guidance to explore conversion of PyTorch models to CoreML.
Before you choose

Requirements & limits

  • The project recommends Python 3.10+ and PyTorch 1.12+.
  • The documented installation uses Conda and installs the repository package in editable mode.
  • The repository separates general instructions, model examples, and the model zoo, so users can consult task-specific starting points.
  • CoreML conversion is described as a separate example path for PyTorch models.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install CVNets in a Conda environment

Prepare the documented Python environment and install the CVNets package.

Before you start

  • Python 3.10 or newer
  • PyTorch 1.12 or newer
  • Conda

Steps

  1. Clone the CVNets repository and change into its directory.

  2. Create and activate a Conda environment using Python 3.10.8.

  3. Install requirements with the repository's requirements.txt and constraints.txt files.

  4. Install the package in editable mode.

Expected outcome

CVNets is installed in the activated Conda environment; the repository's getting-started instructions and examples are the next stage for training or evaluation.

Guide limitations

  • The installation instructions recommend Python 3.10+ and PyTorch 1.12+.
  • This setup sequence does not itself run a training or evaluation job.
