A bug is found in "data.py"

There is a bug line 79 in data.py. When one region (upper level geography) have correspondence to only one geographical unit (lower level geography), "self.geo["region_to_geo"].loc[region_id, geo_name].copy().tolist()" does return a value of not "list" type but "long" type. Hence, I would suggest you to use the following code to get rid of this bug.

geoids = self.geo["region_to_geo"].loc[region_id, geo_name].copy().tolist()
if isinstance(geoids, list):
    return (geoids)
else:
    return ([geoids])
