Type error - size 1 arrays

Question

I have such a python code.

from shapely.geometry import Point, LineString
line = LineString([(lat1,lon1),(lat2,lon2)])
point = Point(lat3, lon3)
line.distance(point) < 1e-8

And here's the error.

TypeError: only size-1 arrays can be converted to Python scalars

What I have tried:

I guess this is raised when the function expects a single value but you pass an array instead. But I don't know how to figure out this problem. What can I do?

Solution 1

Don't pass it an array ... or change the LineString function to accept an array.

We have no idea what that code is meant to do, or what the LineString function does, or how it does it - so we really can't help with any accuracy!
