TypeError: endswith first arg must be str or a tuple of str, not list

[double-fire-0]

File"/mnt/lustre/share/spring/conda_envs/miniconda3/envs/s0.3.3/lib/python3.6/sitepackages/torchvision/datasets/folder.py", line 19, in has_file_allowed_extension return filename.lower().endswith(extensions) TypeError: endswith first arg must be str or a tuple of str, not list

I find this error and solve this error by doing this:
Change line 18 from video_loader.py
from
super(VideoFolder, self).__init__(root, loader, ['.mp4'], transform=transform, target_transform=target_transform)
to
super(VideoFolder, self).__init__(root, loader, '.mp4', transform=transform, target_transform=target_transform)

Then the error will not occur and it works well.
I think it may be a problem about the version of torchvision.
What is your version of torchvision?
For me it is '0.6.0+cu90'
