[Documentation](https://docs.e3nn.org) | [Code](https://github.com/e3nn/e3nn) | [CHANGELOG](https://github.com/e3nn/e3nn/blob/main/.github/CHANGELOG.md) | [Colab](https://colab.research.google.com/drive/1Gps7mMOmzLe3Rt_b012xsz4UyuexTKAf?usp=sharing)

The aim of this library is to help the development of [E(3)](https://en.wikipedia.org/wiki/Euclidean_group) equivariant neural networks. It contains fundamental mathematical operations such as [tensor products](https://docs.e3nn.org/en/stable/api/o3/o3_tp.html) and [spherical harmonics](https://docs.e3nn.org/en/stable/api/o3/o3_sh.html).


## Installation

Important: install pytorch and only then run the command

` pip install --upgrade pip pip install --upgrade e3nn `

For details and optional dependencies, see [INSTALL.md](https://github.com/e3nn/e3nn/blob/main/INSTALL.md)

### Breaking changes e3nn is under development. It is recommanded to install using pip. The main branch is considered as unstable. The second version number is incremented every time a breaking change is made to the code. ` 0.(increment when backwards incompatible release).(increment for backwards compatible release) `
