cuda-bindings 12.9.X Release notes#

Released on TBD

Highlights#

  • Automatic CUDA library path detection based on CUDA_HOME, eliminating the need to manually set LIBRARY_PATH environment variables for installation.

  • The Python overhead of calling functions in CUDA bindings in driver, runtime and nvrtc has been reduced by approximately 30%.

  • Updated the cuda.bindings.runtime module to statically link against the CUDA Runtime library from CUDA Toolkit 12.9.1.

  • cyruntime.getLocalRuntimeVersion now uses pathfinder to find the CUDA runtime.

  • Experimental free-threaded builds are available on PyPI. More details are available in our cuda.bindings Support Policy docs.

Known issues#

  • Updating from older versions (v12.6.2.post1 and below) via pip install -U cuda-python might not work. Please do a clean re-installation by uninstalling pip uninstall -y cuda-python followed by installing pip install cuda-python.
