Installation

Pre-compiled binaries

Pre-compiled binaries of the ARTS interface for macOS and Linux including the ARTS engine for performing RT simulations can be installed in a Miniforge3 environment from the rttools channel:

mamba install -c rttools pyarts

Warning

The pyarts package was created for use with Miniforge3. If you are using Anaconda, you will need to install it into a separate environment with the conda-forge channel:

conda create -n arts -c conda-forge -c rttools pyarts

But compatiblity issues remain, e.g. it has been reported that the package fails to install on Intel Macs with Anaconda. Therefore, we recommend to use Miniforge3.
