From 9137bf698a1e824928e10805c6d1f5f34638d656 Mon Sep 17 00:00:00 2001 From: Bryan Van Deusen Date: Thu, 21 May 2026 22:18:56 -0400 Subject: [PATCH] fix(docker): drop voice deps from runtime image to unblock 3.14 build MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CI broke on the build job: kokoro's resolver walks back to a version that pins numpy<2, which has no cp314 wheel; pip falls back to compiling numpy from source; python:3.14-slim has no compiler; build fails. Removing the voice deps install (torch + faster-whisper + kokoro + soundfile + spacy) from the runtime image: - unblocks the 3.14 build immediately - shrinks the image by ~2 GB (torch alone) - aligns with the explicit operator preference (voice/TTS doesn't pay off in their workflow; conversational chat will get smaller/faster with the new no-tools chat model on GPU, so transcription matters even less) Voice paths in code are already lazily guarded — TYPE_CHECKING-only imports plus try/except inside load_stt_model. With VOICE_ENABLED=false (default), the app starts cleanly with no voice deps installed. With voice enabled, the import error is caught and logged; the feature degrades gracefully rather than crashing. To re-enable voice in a future build, `pyproject.toml` already has the `voice` extra ready: install it with `pip install .[voice]` plus the torch index pin, and download spacy en_core_web_sm. Dockerfile comment documents the path.
