From c4317a7d7e02d4b23b694bbe3ac7e9f33c4b2adb Mon Sep 17 00:00:00 2001 From: Klaus Zimmermann Date: Thu, 29 Oct 2026 14:12:48 +0100 Subject: [PATCH 1/2] Add pathfinder support for cupti64_2026.1.2.dll (CTK 13.2.2) nvidia-cuda-cupti 13.2.86 (CUDA 13.2.2) ships cupti64_2026.1.2.dll on Windows, which the cupti descriptor does not list, so load_nvidia_dynamic_lib("cupti") fails on a machine that only has the 13.2 wheels installed. Found via the PyTorch cu132 Windows nightly, which loads the CUDA wheel libraries through cuda-pathfinder at import time (pytorch/pytorch#202206).
