Start with custom_nodes/qwen3-tts-comfyui/qwen_tts/core/models/modeling_qwen3_tts.py at the Qwen3TTSTalkerModel initialization, where the reported AttributeError occurs. Trace how qwen_tts-comfyui/nodes.py loads the model, then run the qwen3 TTS workflow to reproduce it. Done means the model loads without the missing pad_token_id error and execution completes.
