Please note

If you are reporting an installation or module import issue, please note that
this project only accepts reports about problems with packages downloaded from
the Python Package Index. Conda users should take issues to one of the
following trackers:

• https://github.com/ContinuumIO/anaconda-issues/issues
• https://github.com/conda-forge/shapely-feedstock

Expected behavior and actual behavior.

The overlaps method should return a boolean, but instead raises a GeosException, even though both input geometries are valid. The full exception is listed below:

shapely.errors.GEOSException: TopologyException: side location conflict at -18.954926312734656 -132.64786633489828. This can occur if the input geometry is invalid.

Steps to reproduce the problem.

The script below (minimal.py) using the two WKB files (ShapeA, ShapeB) included in Minimal.zip reproduces the issue.

import shapely

with open("ShapeA", "rb") as file_a:
	shape_a = shapely.from_wkb(file_a.read())

with open("ShapeB", "rb") as file_b:
	shape_b = shapely.from_wkb(file_b.read())

assert shape_a.is_valid
assert shape_b.is_valid
shape_a.overlaps(shape_b)
