Getting 'GS' key error when reading a csv from GCS using gcsfc

Hi I upgraded gcsfs and now I get the following error:

My code is pretty simple:

data = dd.read_csv(file_path, parse_dates=[date_column])\
        .compute()
    return data```

It used to work but all of a sudden it stopped working.
file_path = gs://mybuck/res.csv

```File "main.py", line 51, in run
    data = load_parse_file(file_path=args.input_file)
  File "/FbProphet/prophet_gcp/utils.py", line 15, in load_parse_file
    data = dd.read_csv(file_path, parse_dates=[date_column])\
  File "/work/miniconda/lib/python3.7/site-packages/dask/dataframe/io/csv.py", line 578, in read
    **kwargs
  File "/work/miniconda/lib/python3.7/site-packages/dask/dataframe/io/csv.py", line 405, in read_pandas
    **(storage_options or {})
  File "/work/miniconda/lib/python3.7/site-packages/dask/bytes/core.py", line 93, in read_bytes
    fs, fs_token, paths = get_fs_token_paths(urlpath, mode="rb", storage_options=kwargs)
  File "/work/miniconda/lib/python3.7/site-packages/dask/bytes/core.py", line 425, in get_fs_token_paths
    fs, fs_token = get_fs(protocol, options)
  File "/work/miniconda/lib/python3.7/site-packages/dask/bytes/core.py", line 571, in get_fs
    cls = _filesystems[protocol]
KeyError: 'gs'

Start with the reported dask.dataframe.read_csv call and the traceback through dask/bytes/core.py, especially get_fs_token_paths and get_fs. Reproduce the gs:// read with the upgraded gcsfs setup and compare filesystem registration behavior; done means the CSV loads without KeyError: 'gs'.
