argopy.stores.s3store

class s3store(*args, **kwargs)

Argo s3 file system

Inherits from httpstore but rely on s3fs.S3FileSystem through the fsspec ‘s3’ protocol specification.

By default, this store will use AWS credentials available in the environment.

If you want to force an anonymous session, you should use the anon=True option.

In order to avoid a no credentials found error, you can use:

>>> from argopy.utils import has_aws_credentials
>>> fs = s3store(anon=not has_aws_credentials())
