Subject: [PATCH] Dockerfile: build tiny-cuda-nn with --no-build-isolation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

pip's isolated build environment pulls the latest setuptools, which no
longer ships pkg_resources (removed in recent setuptools), failing
tcnn's setup.py. The image already pins setuptools<70, which provides
pkg_resources — disable build isolation so it is actually used.
