-  summary: 'RAPIDS Suite - Open GPU Data Science'
-  description: |
-    Meta-package for the RAPIDS suite of software libraries. RAPIDS gives you the freedom to execute end-to-end data science
-    and analytics pipelines entirely on GPUs. It relies on NVIDIA® CUDA® primitives for low-level compute optimization,
-    but exposes that GPU parallelism and high-bandwidth memory speed through user-friendly Python interfaces.
