{"id":4136,"library":"nvidia-cuda-cupti-cu11","title":"NVIDIA CUDA CUPTI Runtime (CUDA 11)","description":"This package provides the CUDA Profiling Tools Interface (CUPTI) runtime libraries specifically for CUDA 11.x. It's a low-level dependency, typically used by higher-level deep learning frameworks like PyTorch and TensorFlow to enable GPU acceleration and profiling capabilities. The current version is 11.8.87. Releases are tied to NVIDIA CUDA Toolkit updates.","status":"active","version":"11.8.87","language":"en","source_language":"en","source_url":"https://developer.nvidia.com/cuda-toolkit","tags":["nvidia","cuda","cupti","gpu","profiling","deep learning","pytorch","tensorflow","low-level"],"install":[{"cmd":"pip install nvidia-cuda-cupti-cu11","lang":"bash","label":"Install via pip"}],"dependencies":[],"imports":[],"quickstart":{"code":"import os\ntry:\n    import torch\n    if torch.cuda.is_available():\n        print(\"SUCCESS: CUDA is available via PyTorch!\")\n        print(f\"  CUDA device name: {torch.cuda.get_device_name(0)}\")\n        print(\"  This indicates underlying CUDA libraries (like CUPTI) are functional.\")\n    else:\n        print(\"FAILURE: CUDA is NOT available via PyTorch.\")\n        print(\"  Check NVIDIA drivers, CUDA Toolkit installation, and compatibility.\")\nexcept ImportError:\n    print(\"WARNING: PyTorch not installed.
