CUDA Python is supported on all platforms that CUDA is supported. Specific dependencies are as follows:
- Driver: Linux (450.80.02 or later) Windows (456.38 or later)
- CUDA Toolkit 12.0 to 12.2
- Python 3.8 to 3.11
Only the NVRTC redistributable component is required from the CUDA Toolkit. CUDA Toolkit Documentation Installation Guides can be used for guidance. Note that the NVRTC component in the Toolkit can be obtained via PiPy, Conda or Local Installer.
CUDA Python follows NEP 29 for supported Python version guarantee.
Before dropping support, an issue will be raised to look for feedback.
Refer to documentation for installation options and requirements: Installation

CUDA Samples rewriten using CUDA Python are found in examples.
Custom extra included examples:
examples/extra/jit_program_test.py: Demonstrates the use of the API to compile and launch a kernel on the device. Includes device memory allocation / deallocation, transfers between host and device, creation and usage of streams, and context management.examples/extra/numba_emm_plugin.py: Implements a Numba External Memory Management plugin, showing that this CUDA Python Driver API can coexist with other wrappers of the driver API.
