How to install MoviePy on a remote SSH server without an A/V card?

I installed MoviePy with sudo pip install moviepy. However, I get the following error when importing it:

$ python

It appears that the errors have to do with my server not having an audio card. I am connected via SSH, and I have X11 forwarding enabled, but not audio.

Is there a way to run MoviePy without connecting it to an A/V card?

It may be due to the fact that importing moviepy.editor does a lot of things (like finding pygame and initializing pygame's sound module). In that case you can still use MoviePy by not using moviepy.editor, and instead importing directly the objects you need. Try this:

from moviepy.video.io import VideoFileClip
clip = VideoFileClip("some_video.mp4").subclip(0, 3)
clip.write_videofile("my_new_video.mp4")

Indeed, importing from moviepy.video.io makes the module import correctly. It works great; thanks for making this! 👍
