cuda-pathfinder 1.4.3 Release notes#

Released on Mar 16, 2026

Highlights#

  • Fix CTK canary probing when it is reached from plain Python scripts that do not use an if __name__ == "__main__" guard. The canary now runs in a fully isolated Python subprocess without re-entering the caller’s script during child-process startup. (PR #1768)

  • Make the canary subprocess resolve cuda.pathfinder from the same import root as the parent process. This avoids mixed source-tree versus wheel imports in wheel-based test environments and keeps the probe behavior consistent across source and installed-package workflows. (PR #1768)
