-# 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.
+# numpy: no pin -- numpy 1.x (the old workaround for a bug in pyannote.audio
+# 3.1.1, not 3.4.0) has NO Python 3.13 wheel at all, so it's not just
+# unneeded, it's uninstallable. Flag any numpy-related error if one appears.

+# huggingface_hub: pinned to 0.35.0 -- pyannote.audio 3.4.0's own internal
+# code (pipeline.py) still calls hf_hub_download(..., use_auth_token=...),
+# a parameter that huggingface_hub REMOVED entirely in its 1.0.0 release.
+# Left unpinned, pip resolves to the newest available (1.0.0+) and breaks
+# at pipeline load time with:
+#   TypeError: hf_hub_download() got an unexpected keyword argument 'use_auth_token'
+# 0.35.0 is the newest 0.x release (confirmed to still support the old
+# argument) and also satisfies this Space's own base-image floor pin of
+# huggingface-hub>=0.30 baked into an earlier build layer.
