- Print the active ComfyUI Python executable with install.py
- Remove misleading requirements.txt and package-specific repair advice
- Add regression coverage for installation guidance
Fix dependency checker false missing-package warnings
Technical details:
- Stop using eager module imports as the primary dependency probe
- Check module specs and installed distributions before fallback import
- Reduce false negatives for heavy packages like diffusers during background checks
Removed torchcodec from requirements.txt and install.py to eliminate the FFmpeg
system dependency that was causing Windows installation failures.
Implementation:
- Removed torchcodec>=0.2.0 from requirements.txt
- Removed torchcodec>=0.2.0 from install.py core_packages list
- Removed torchaudio 2.9+ migration warnings (no longer applicable)
- Added AudioProcessingUtils.safe_load_audio() utility for robust audio loading
- Updated all audio loading calls to use fallback-aware utility function
Audio Loading Changes:
- character_voices_node.py: Uses safe_load_audio() with fallback support
- tts_text_node.py: Uses safe_load_audio() for narrator and character voices (2x)
- tts_srt_node.py: Uses safe_load_audio() for narrator voice
- higgs_audio_tts_processor.py: Uses safe_load_audio() (2x)
- higgs_audio_srt_processor.py: Uses safe_load_audio() (2x)
- index_tts_processor.py: Uses safe_load_audio() (2x)
- f5tts_streaming_adapter.py: Uses safe_load_audio()
- higgs_audio_adapter.py: Uses safe_load_audio()
- subprocess.py: Uses safe_load_audio()
Compatibility:
- torchaudio.load() works fine with fallback backends (soundfile, scipy)
- No quality loss - only negligible audio loading speed difference (~milliseconds)
- All existing audio formats supported
- Better error handling with graceful fallbacks
Fix critical audio loading and model download dependencies
- Add missing torchcodec dependency required by torchaudio for audio file loading
- Fix torchcrepe import checking for packages installed with --no-deps
- Fix German (havok2) ChatterBox model download pointing to wrong subdirectory
- German model now correctly uses finetuned_by_h2 folder with complete model files
- Fixed engine initialization issue where adapter never called initialize_engine
- Fixed model configuration key mismatch (generation_repo vs generation_model)
- Fixed tokenizer download file name (model.pth vs pytorch_model.bin)
- Fixed tensor dimension issues for ComfyUI audio output format
- Added comprehensive multi-speaker mode system with three options:
* Custom Character Switching: Use [Alice], [Bob] with character voice files
* Native Multi-Speaker (System Context): Use [SPEAKER0], [SPEAKER1] with opt_second_narrator
* Native Multi-Speaker (Conversation): Same as above but conversation history mode
- Removed audio_priority widget, now follows standard TTS priority logic
- Fixed mode selection bug where config was read from wrong object
- Added proper audio format handling for Character Voices in native modes
- Fixed pause tag support in all modes including native multi-speaker
- Improved tooltips to clarify mode requirements and text formats
