Point no longer accepts arrays of shape (1,)

[martinfleis]

Expected behavior and actual behavior.

Shapely 2.0 no longer accepts arrays of shape (1,) as a valid input in Point constructor, while shapely 1.8.5 does and does not emit any warning while doing that.

Steps to reproduce the problem.

shapely 2.0b1:

In [1]: import numpy
   ...: import shapely
   ...: from shapely.geometry import Point
   ...: shapely.__version__
Out[1]: '2.0b1'

In [2]: x, y = numpy.array([1]), numpy.array([1])
   ...: x, y
Out[2]: (array([1]), array([1]))

In [3]: Point(x, y)
---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
Input In [3], in <cell line: 1>()
----> 1 Point(x, y)

File ~/mambaforge/envs/geo_dev/lib/python3.10/site-packages/shapely/geometry/point.py:77, in Point.__new__(self, *args)
     74     geom = shapely.points(np.array(args))
     76 if not isinstance(geom, Point):
---> 77     raise ValueError("Invalid values passed to Point constructor")
     78 return geom

ValueError: Invalid values passed to Point constructor

The same works correctly with 1.8.5:

In [3]: Point(x, y)
Out[3]: <shapely.geometry.point.Point at 0x10679b730>

Operating system

macOS 13.0, Ubuntu

Good catch, thanks for the report. I think it is fine to allow that again.
