MarsSeed [1] filed a deletion request for cntk-cuda [2]: Discontinued Microsoft AI toolkit. Last release was in April 2019. [a] Package broken since Oct 2019, because it hardcodes Python 3.7 site- packages path, and Arch shipped Python 3.8 then. Last comment apart from mine was made in 2021 about the same problem. Not useful to keep this package. Active development hasn't continued after 2019: only 5 minor commits in 2020, then one commit in 2022 by a Microsoft bot. [b] Current owner @joaquinito2051 just adopted 100+ packages throughout the last 1.5-2 years, but he never touched almost any of them, or maybe made one or two very trivial changes somewhere. He has never responded to any of my comments ever. Safe to delete this unneeded and defunct package.
