I’m running into an issue with shapely that is baffling me. Perhaps someone here can help out?
When running shapely directly from a python 3.8 interpreter, it works as expected: >>> import shapely >>> shapely.__version__ '1.8.0' >>> from shapely.geometry import Polygon >>> bounds = [-164.29635821669632, 54.64251856269729, -163.7631779798799, >>> 54.845450778742546] >>> print(Polygon.from_bounds(*bounds)) POLYGON ((-164.2963582166963 54.64251856269729, -164.2963582166963 54.84545077874255, -163.7631779798799 54.84545077874255, -163.7631779798799 54.64251856269729, -164.2963582166963 54.64251856269729)) However, if I put this exact same code into my Flask app (currently running under the Flask development environment) as part of handling a request, I get an empty polygon: >>> import shapely >>> print(shapely.__version__) >>> from shapely.geometry import Polygon >>> print(Polygon.from_bounds(*bounds)) Output: 1.8.0 POLYGON EMPTY In fact, *any* attempt to create a polygon gives the same result: >>> test = Polygon(((1, 1), (2, 1), (2, 2))) >>> print(test) POLYGON EMPTY What am I missing here? Why doesn’t it work as part of a Flask request call? --- Israel Brewster Software Engineer Alaska Volcano Observatory Geophysical Institute - UAF 2156 Koyukuk Drive Fairbanks AK 99775-7320 Work: 907-474-5172 cell: 907-328-9145 -- https://mail.python.org/mailman/listinfo/python-list
