使用 Google Cloud API python 示例异步记录代码给我属性错误

Question

https://github.com/GoogleCloudPlatform/python-docs-samples/blob/master/speech/cloud-client/transcribe_async.py

我正在使用 Google Speech API 中的示例 python 代码将长（大于 1 分钟）的音频文件从语音转换为文本。我如何运行 PyCharm 中的代码，以便它使用我创建的 API 密钥（用于向我的帐户收费）将我的音频文件（波形格式）转换为文本，而无需 'NoneType' 错误？

我直接在代码中添加了音频文件的路径（第73行）。我还在 'path' 前面添加了“--”以使其处理 LOC（第 73 行）。我得到的错误如下：

**C:\Users\Dave\AppData\Local\Programs\Python\Python37\python.exe C:/Users/Dave/Desktop/mizu/gcapi.py
Traceback (most recent call last):
  File "C:/Users/Dave/Desktop/mizu/gcapi.py", line 75, in <module>
    if args.path.startswith('gs://'):
AttributeError: 'NoneType' object has no attribute 'startswith'
Process finished with exit code1**

if __name__ == '__main__':
    parser = argparse.ArgumentParser(
        description=__doc__,
        formatter_class=argparse.RawDescriptionHelpFormatter)
    parser.add_argument(

    if args.path.startswith('gs://'):
        transcribe_gcs(args.path)
    else:
        transcribe_file(args.path)

我希望它输出一个文件，其中包含正在转录的音频文件中的文本，并在此过程中向我的帐户收费。

https://docs.python.org/3/library/argparse.html

使用 parser.add_argument('--path', help='C:/Users/Dave/Desktop/mizu/output.wav') 您刚刚定义了您的脚本在从命令行调用后可以接受参数 --path，并且该文本只是在有人使用 [=14 启动您的脚本时显示的帮助文本=] 参数。

因此，如果 if __name__ == '__main__' 所在的脚本名称为 myscript.py，您实际上必须像这样启动脚本：

python myscript.py --path C:/Users/Dave/Desktop/mizu/output.wav

但是，在这种情况下，该例程没有任何意义，您的解决方案是摆脱那些额外的代码。只做：

if __name__ == '__main__':
    transcribe_file('C:/Users/Dave/Desktop/mizu/output.wav')
