Moviepy is a good library for editing videos on python. But it seems like there are few bugs with the library. One of them is associated with the audioclip.subclip method:

Name of Error: “AttributeError: ‘NoneType’ object has no attribute ‘stdout'”

To fix the error:

Solution 1: Upgrade the moviepy library to version 1.0.3

  • Open terminal
  • Type pip install moviepy –upgrade

Solution2: Update the source code of AudioFileClip.py

  1. Make sure you have moviepy version 1.0.1
  2. go to the moviepy directory:
    cd /usr/local/lib/python3.7/dist-packages/moviepy/
  3. edit the AudioFileClip class at line 93
  4. comment these lines:
    # def __del__(self):
    # self.close()
