Sphericart is a library for the efficient calculation of the spherical harmonics and their derivatives in Cartesian coordinates.
This release brings a lot of improvements:
- the CPU version of the code is now written in C++ instead of C, the main API entry point is the `SphericalHarmonics<T>` class
- the code is integrated with PyTorch and TorchScript in the `sphericart-torch` package, allowing backward propagation of gradients
- the `sphericart-torch` package also includes a CUDA version, computing spherical harmonics on GPUs
- the `sphericart-torch` package allows to patch e3nn, using sphericart implementation to compute spherical harmonics in e3nn-based models
