Description

Qwen/Qwen3-TTS-12Hz-1.7B-Base throws a segmentation fault when running the example provided by Qwen on Hugging Face

https://huggingface.co/Qwen/Qwen3-TTS-12Hz-1.7B-CustomVoice

Reproduction

import torch import soundfile as sf from qwen_tts import Qwen3TTSModel

model = Qwen3TTSModel.from_pretrained( "Qwen/Qwen3-TTS-12Hz-1.7B-Base", device_map="cuda:0", dtype=torch.bfloat16, attn_implementation="flash_attention_2", )

ref_audio = "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen3-TTS-Repo/clone.wav" ref_text = "Okay. Yeah. I resent you. I love you. I respect you. But you know what? You blew it! And thanks to you."

wavs, sr = model.generate_voice_clone( text="I am solving the equation: x = [-b ± √(b²-4ac)] / 2a? Nobody can — it's a disaster (◍•͈⌔•͈◍), very sad!", language="English", ref_audio=ref_audio, ref_text=ref_text, ) sf.write("output_voice_clone.wav", wavs[0], sr)
