Supported Machines and Environments

The current Gen3 2D DRP (later than w.2026.07) is supported on AlmaLinux 9 only.

The PFS 2D DRP pipeline is built upon the LSST pipeline, and requires that it be installed. These pipelines use Python 3.13 features; lower python versions (python ≥ 3.9) may be acceptable for using the datamodel package without the pipeline.

Support for additional systems may be added in the future.

Prerequisites

The LSST v30 prerequisites are listed in the official webpage. For AlmaLinux 9, patch and git are required:

sudo dnf install patch git
