Getting Started

Runtime requirements

  • CUDA Toolkit version 12.8

    • Only the NVRTC redistributable component is required from the CUDA Toolkit. CUDA Toolkit Documentation Installation Guide can be used for guidance.

    • Note that the NVRTC component in the Toolkit can be obtained via PYPI, Conda or Local Installer.

  • Python version >= 3.9

Installing from PyPI

$ pip install cupti-python

Setting for CUPTI C Library

  • CUPTI Python has a dependency on nvidia-cuda-cupti-cu12. It uses the CUPTI C library libcupti.so from nvidia-cuda-cupti-cu12.

  • However, if nvidia-cuda-cupti-cu12 is uninstalled, the LD_LIBRARY_PATH environment variable needs to be set to the directory in which libcupti.so is present. When the CUDA Toolkit is installed, libcupti.so is present under $CUDA_TOOLKIT_INSTALL_PATH/extras/CUPTI/lib64.

  • e.g. If the CUDA_TOOLKIT_INSTALL_PATH is /usr/local/cuda-12.8:

$ export LD_LIBRARY_PATH=/usr/local/cuda-12.8/extras/CUPTI/lib64
