CUDA Python 11.7.1 Release notes#
Released on June 29, 2022
Highlights#
Fix error propagation in CUDA Runtime bindings
Resolves issue #22
Limitations#
Source builds#
CUDA Python no longer re-declares CUDA types, instead it uses the types from CUDA C headers. As such source builds now need to access to latest CTK headers. In particular: 1. “$CUDA_HOME/include” has latest CTK headers 2. CTK headers have all types defined
(2) Certain CUDA types are not declared on mobile platforms and may face a “has not been declared” error during source builds. A temporary workaround is to use the headers found in nvidia/headers/cuda. In particular CUDA Python needs the following headers and their dependencies: - cuda.h - cudaProfiler.h - driver_types.h - cuda_runtime.h - nvrtc.h
This a short-term limitation and will be relaxed in a future release.
