This is the development branch of DiffSharp 1.0.

NOTE: This branch is undergoing development. It has incomplete code, functionality, and design that are likely to change without notice; when using TorchSharp backend, only x64 platform is currently supported out of the box, see [DEVGUIDE.md] for more details.

DiffSharp is a tensor library with support for differentiable programming. It is designed for use in machine learning, probabilistic programming, optimization and other domains.

Key features

• Nested and mixed-mode differentiation
• Common optimizers, model elements, differentiable probability distributions
• F# for robust functional programming
• PyTorch familiar naming and idioms, efficient LibTorch CUDA/C++ tensors with GPU support
• Linux, macOS, Windows supported
• Use interactive notebooks in Jupyter and Visual Studio Code
• 100% open source
