安装MeloTTS报错解决方法

0. 研究背景

在国内环境中安装MeloTTS往往会报错，因为有些资料需要从国外网站中下载。

1. huggingface无法访问问题

首先需要解决国内无法访问huggingface的问题，可以配置使用国内镜像来解决。

export HF_ENDPOINT=https://hf-mirror.com

2. nltk无法下载问题

参考文档

3. unidic无法下载问题

在执行python -m unidic download 时会报错，由于网络原因。

解决方式：

1. 从 https://cotonoha-dic.s3-ap-northeast-1.amazonaws.com/unidic-3.1.0.zip 中下载
2. 把下载后的文件上传到服务器中的 /root/miniconda3/envs/tts/lib/python3.9/site-packages/unidic，并把 unidic-3.1.0.zip 重命名为 unidic.zip
3. 修改 download.py，找到 93 行，也就是在 download_version() 函数中，注释掉除了 download_and_clean() 之外的内容
4. 修改 download_and_clean() 中的参数，你可以随意设置
5. 修改 download.py 中的 62 行，注释 download_process()
6. 执行 python -m unidic download

参考文件

给这个压缩包赋值执行权限

chmod +x unidic.zip

4. 下载模型

在melo/download_utils.py中可以找到对应的下载地址

DOWNLOAD_CKPT_URLS = {

5. 阻止联网下载文件

默认会从网上下载模型和配置文件，需要修改melo/download_utils.py源码，阻止联网下载文件。

def load_or_download_config(locale, use_hf=True, config_path=None):
    if config_path is None:
        language = locale.split('-')[0].upper()
        if use_hf:
            assert language in LANG_TO_HF_REPO_ID
            config_path = hf_hub_download(repo_id=LANG_TO_HF_REPO_ID[language], filename="config.json")
        #else:
        #    assert language in DOWNLOAD_CONFIG_URLS
        #    config_path = cached_path(DOWNLOAD_CONFIG_URLS[language])
    return utils.get_hparams_from_file(config_path)

def load_or_download_model(locale, device, use_hf=True, ckpt_path=None):
    if ckpt_path is None:
        language = locale.split('-')[0].upper()
        if use_hf:
            assert language in LANG_TO_HF_REPO_ID
            ckpt_path = hf_hub_download(repo_id=LANG_TO_HF_REPO_ID[language], filename="checkpoint.pth")
        #else:
        #    assert language in DOWNLOAD_CKPT_URLS
        #    ckpt_path = cached_path(DOWNLOAD_CKPT_URLS[language])
    return torch.load(ckpt_path, map_location=device)

修改app.py

'EN': TTS(language='EN', device=device, use_hf=False, config_path='/root/autodl-tmp/tts/model/English/config.json', ckpt_path='/root/autodl-tmp/tts/model/English/checkpoint.pth')

6. 解决AttributeError: module ‘botocore.exceptions’ has no attribute 'HTTPClientError’报错问题

botocore>=1.34.98
cached_path>=1.6.2
boto3>=1.35.81

参考文档

7. 解决nltk_data报错问题

报错信息：

  Resource averaged_perceptron_tagger_eng not found.
  Please use the NLTK Downloader to obtain the resource:

  >>> import nltk
  >>> nltk.download('averaged_perceptron_tagger_eng')
  
  For more information see: https://www.nltk.org/data.html

解决方法：

git clone https://github.com/nltk/nltk_data.git

找到nltk_data/packages/taggers/averaged_perceptron_tagger_eng.zip复制到/root/nltk_data/taggers解压。

8. 报错cmudict解决方法

将上面下载的nltk_data解压出来的cmudict目录放置到/root/nltk_data路径下。
