CuPy-Xarray: Xarray on GPUs!

Overview

CuPy-Xarray is a Python library that leverages CuPy, a GPU array library, and Xarray, a library for multi-dimensional labeled array computations, to enable fast and efficient data processing on GPUs. By combining the capabilities of CuPy and Xarray, CuPy-Xarray provides a convenient interface for performing accelerated computations and analysis on large multidimensional datasets.

Installation

cupy-xarray will use an existing cupy installation, hence cupy needs to be installed manually! Please follow cupy's install instructions at https://docs.cupy.dev/en/stable/install.html.

CuPy-Xarray can be installed using pip or conda:

From Conda Forge:

conda install cupy-xarray -c conda-forge

From PyPI:

pip install cupy-xarray

The latest version from Github:

pip install git+https://github.com/xarray-contrib/cupy-xarray.git
