 #
-# IMPORTANT: torch/torchaudio are now EXACT pins, not floors. An open ">="
-# let pip grab whatever is newest at build time, which on a fresh Python 3.13
-# build resolved to a torch/torchaudio pairing that doesn't expose
-# torchaudio.AudioMetaData the way pyannote.audio 3.4.0 expects -- causing
-# an ImportError at startup. Pinning to the exact version we've actually
-# verified working avoids that drift.
+# This Space builds from `FROM docker.io/library/python:3.13` (a Docker SDK
+# Space) -- confirmed from the build log. All versions below have been
+# verified to have real cp313 (Python 3.13) wheels available; nothing here
+# should trigger a "no matching distribution" error like the previous
+# attempt did.
 #
-# ALSO REQUIRED: set this Space to Python 3.10 or 3.11 in your README.md
-# YAML header, e.g.:
-#     python_version: "3.11"
-# Everything here has only been verified on 3.10/3.11. Python 3.13 is very
-# new and this whole stack (torch/torchaudio/pyannote.audio) hasn't been
-# confirmed compatible with it.
+# torch/torchaudio: pinned to 2.6.0, the EARLIEST version with a Python 3.13
+# wheel for torchaudio (torch alone had 3.13 support a bit earlier, at 2.5.1,
+# but torchaudio didn't catch up until 2.6.0, so both must move together).
+# This is also very close to the checkpoint's original training environment
+# (torch 2.7.1+cu118, per the "Model was trained with torch..." warning we
+# saw earlier) -- if 2.7.1 ever gets a 3.13 wheel and you want to move even
+# closer to that, it's worth revisiting, but 2.6.0 has been verified
+# installable today.
+#
+# numpy: the earlier `numpy<2.0` pin (a workaround for a bug in an older
+# pyannote.audio version, not 3.4.0) has been DROPPED -- numpy 1.x has no
+# Python 3.13 wheel at all, so it's not just unnecessary now, it's
+# uninstallable. If you hit any numpy-related error after this change,
+# flag it -- that would mean pyannote.audio 3.4.0 has its own numpy 2.x
+# issue we haven't seen yet, not a repeat of the old bug.
