Getting Started

This section provides an installation and a quick starting guide.

Installation

To install the latest stable release of SCL, run the following command:

pip install sony-custom-layers

By default, no framework dependencies are installed. To install SCL including the latest tested dependencies (up to patch version) for TensorFlow:

pip install sony-custom-layers[tf]

To install SCL including the latest tested dependencies (up to patch version) for PyTorch/ONNX/OnnxRuntime:

pip install sony-custom-layers[torch]
