migration to numpy 2 #194
Description
Hello,
I am currently using Pandana for its efficient implementation of Contraction Hierarchies for fast routing computations. However, I am experiencing compatibility issues when trying to run it in a Python 3.12 environment with NumPy 2.1.3.
I attempted to compile Pandana from source, and the compilation seemed successful. However, when I try to instantiate a network and run the example script, I encounter the following error:
Building network from file: 'D:\\Users\\AL\\repos\\pandana\\tests\\osm_sample.h5'
Traceback (most recent call last):
File "D:\Users\AL\repos\pandana\examples\simple_example.py", line 41, in <module>
net = pdna.Network(nodes.x, nodes.y, edges["from"], edges.to,

warnings.warn(UnclosedFileWarning(msg))
Is there any plan to update Pandana for compatibility with NumPy 2.x? I would appreciate any guidance on resolving this issue or suggestions for alternative libraries that could meet my fast routing needs.
Thank you for your assistance!
