I have installed soundfile and pysoundfile, but still error.

Download ffmpeg and add Path var

or edit the code

torchaudio.save("output1.wav", torch.from_numpy(wavs[0]), 24000, format='wav')

to

soundfile.write("output1.wav", wavs[0], 24000)

已解决！ OS: windows 11

在 Anaconda 环境中安装指定的 Python 包

创建并激活新的 Conda 环境 conda create -n myenv python=3.9 conda activate myenv

使用 conda 安装 ipython 和 tqdm conda install ipython tqdm

使用 pip 安装其余的包 pip install omegaconf==2.3.0 torch==2.1.0 einops vector_quantize_pytorch transformers==4.41.1 vocos

pip install soudfile

test.py

import soundfile import ChatTTS

chat = ChatTTS.Chat() chat.load_models(source='local', local_path='D:\zhanxy\ChatTTS\ChatTTS\model2\chatTTS') texts = ["由于连接方在一段时间后没有正确答复或连接的主机没有反应，连接尝试失败。",]

wavs = chat.infer(texts, use_decoder=True) soundfile.write("output1.wav", wavs[0][0], 24000)

重新 git pull

test.py 有点错误，改用 soundfile

[jianchang512]

2楼不是说了吗，不要使用 torchaudio ，删掉相关代码，使用 soundfile

pip install soundfile

换成soundfile会报这个错

[libukai]

soundfile.write("output1.wav", wavs[0], 24000)

代码需要修正

soundfile.write("output1.wav", wavs[0][0], 24000)

推荐一下我自己 fork 的版本，ChatTTS-Control

[Yinshuofeng]

感谢楼上 可以了!

2楼不是说了吗，不要使用 torchaudio ，删掉相关代码，使用 soundfile

pip install soundfile

我用你说的第一种方法运行没问题，就是需要安装 ffmpeg 软件

apt update
apt install ffmpeg -y
ffmpeg -version

[njhouse365]

还是soundflie可靠
