The documentation for PyFilesystem's s3fs (S3 filesystem) says that it is only supported in python 2 because boto only supports python 2.
https://pyfilesystem.readthedocs.io/en/latest/s3fs.html
However Boto3 is released and stable:
I just wanted to verify that the documentation is still accurate on this point. I'm unable to import fs.s3fs
in my python 3 environment.
The S3 filesystem does support boto3, there's an old version of the docs lurking around that can throw you off. Also a separate pip install is necessary for this filesystem.
Documented in a separate repo here:
https://github.com/PyFilesystem/s3fs
pip install fs-s3fs
from fs_s3fs import S3FS
s3fs = S3FS('mybucket')
