CuPy : A NumPy-compatible array library accelerated by CUDA

Website | Docs | Install Guide | Tutorial | Examples | API Reference | Forum

CuPy is an implementation of NumPy-compatible multi-dimensional array on CUDA. CuPy consists of the core multi-dimensional array class, cupy.ndarray, and many functions on it.

Installation

Wheels (precompiled binary packages) are available for Linux and Windows. Choose the right package for your CUDA Toolkit version.

See the Installation Guide if you are using Conda/Anaconda or to build from source.

Run on Docker

Use NVIDIA Container Toolkit to run CuPy image with GPU.

$ docker run --gpus all -it cupy/cupy
