Simple moviepy script, getting error: unhashable type: 'list'

[JacobStephenson97]

i'm working on a little script to concat all clips in a folder with a small transition using moviepy, but I'm unable to run it as I'm getting the error unhashable type 'list'. I've been reading through many posts about this error and I understand that you're unable to hash a list, and casting to a tuple can fix the problem, i've tried multiple suggestions from other answers but can't fully understand why my code isn't fully working

from moviepy.editor import concatenate_videoclips
from moviepy.video.io.VideoFileClip import VideoFileClip  
import os
 

clips = []
    for filename in os.listdir('D:/Clip Project/ClipsTest'):
        if filename.endswith(".mp4"):
            clips.append(VideoFileClip('D:/Clip Project/ClipsTest/' + filename))
    clips = [clip.crossfadein(1) for clip in clips]
    video = concatenate_videoclips(clips, padding=-1, method='compose', )
    video.write_videofile('D:/Clip Project/ClipsTest/League-' + '.mp4', threads=4, fps=24)

This is the code I orginally ran into the problem with and am struggling to fix, any tips would be amazing!

Here is the full error:

    importer = sys.path_importer_cache[path_item]
TypeError: unhashable type: 'list'

Is it possible this is an issue with moviepy itself? I've looked into the documentation below but to no avail, as well as fiddled with the imports.

Hey, I’ll get a chance to investigate further today, but at a cursory glance it looks like a problem with your installation. The error occurs as soon as you import moviepy, so there is no problem with your code.

I've had a deeper look.

Would you mind adding print(fx.__path__) on line 12 of C:\Users\user\AppData\Local\Programs\Python\Python38\lib\site-packages\moviepy\video\fx\all\__init__.py and then importing moviepy.editor and report back what is printed?

On my system, it prints ['/Users/tomburrows/Python/moviepy-dev/moviepy/moviepy/video/fx'], and then in pgkutil.iter_modules:126, that variable is mapped onto get_importer which then uses '/Users/tomburrows/Python/moviepy-dev/moviepy/moviepy/video/fx' as an index in a dictionary.

Thanks a ton for looking into this! I added the print statement and it prints a similar path.

How strange! In that case, I’d recommend further debugging pkgutil.py, for instance, a print statement the line before the crash to see what path_item contains and try to find out how your path string turns into a list.

Note that the code that is currently failing is being likely to be replaced in v2.0. See #1105.

Closing due to a lack of response after debugging suggestions + information on v2.0 of MoviePy.
