Importing gcsfs in datalab is giving an error

When I import gcsfs in datalab,

import gcsfs

I've this invalid syntax error which is related to the package fsspec. Is it something to do with versions

    exec(code_obj, self.user_global_ns, self.user_ns)

To expand on Claros answer, the underlying problem is the fsspec package, which gcsfs inherits from. fsspec's recent 0.8.0 version implemented f-strings, which is causing the error. To fix it, simply install the latest fsspec version that still supports Python 3.5, i.e.

!pip install fsspec==0.6.2

https://pypi.org/project/fsspec/0.6.2/

You may also have to downgrade gcsfs. I got it to work with

!pip install  --upgrade gcsfs==0.5.3

You're using Python 3.5, while f-strings is a feature implemented in Python 3.6. Either you find a compatible version of your package with Python 3.5, or you upgrade to Python 3.6+.
