New Backend support clEsperanto now comes with support for CUDA 12 and Metal. While OpenCL remain the default backend, you can now install pyclesperanto with additional backend pip install pyclesperanto // only install opencl pip install pyclesperanto[cuda] // not available in MacOS pip install pyclesperanto[metal] // only available in MacOS pip install pyclesperanto[all] // install all possible configuration and you can select and choose you backend at the start of the import: import pyclesperanto as cle cle.list_avaiable_backend() >>> ['opencl', 'cuda'] cle.select_backend("cuda") DLPack support And now the Array object support DLPack which allows both way copy-free interoperability with other GPU library that uses same backend and support the same protocol (e.g. cupy, torch, ...) import pyclesperanto as cle import cupy as cp cle.select_backend("cuda") cp_array = cp.random.random((10,10), dtype=cp.float32) cle_array = cle.from_dlpack(cp_array) Full Changelog: https://github.com/clEsperanto/pyclesperanto/compare/0.21.4...0.22.0
