CoreNet is a deep neural network toolkit that allows researchers and engineers to train standard and novel small and large-scale models for variety of tasks, including foundation models (e.g., CLIP and LLM), object classification, object detection, and semantic segmentation.

You will need Git LFS (instructions below) to run tests and Jupyter notebooks (instructions) in this repository, and to contribute to it so we recommend that you install and activate it first.
On Linux we recommend to use Python 3.10+ and PyTorch (version >= v2.1.0), on macOS system Python 3.9+ should be sufficient.
Note that the optional dependencies listed below are required if you'd like to make contributions and/or run tests.
For Linux (substitute apt for your package manager):
sudo apt install git-lfs
git clone git@github.com:apple/corenet.git
cd corenet
git lfs install
git lfs pull
# The following venv command is optional, but recommended. Alternatively, you can create and activate a conda environment.
python3 -m venv venv && source venv/bin/activate
python3 -m pip install --editable .To install optional dependencies for audio and video processing:
sudo apt install libsox-dev ffmpegFor macOS, assuming you use Homebrew:
brew install git-lfs
git clone git@github.com:apple/corenet.git
cd corenet
cd \$(pwd -P) # See the note below.
git lfs install
git lfs pull
# The following venv command is optional, but recommended. Alternatively, you can create and activate a conda environment.
python3 -m venv venv && source venv/bin/activate
python3 -m pip install --editable .To install optional dependencies for audio and video processing:
brew install sox ffmpegNote that on macOS the file system is case insensitive, and case sensitivity
can cause issues with Git. You should access the repository on disk as if the
path were case sensitive, i.e. with the same capitalization as you see when you
list the directories ls. You can switch to such a path with the cd $(pwd -P)
command.
