Error when creating transport network

[johanngrobe]

Describe the bug
I tried to create a transport network. For this I downloaded the latest osm.pbf of Germany from Geofabrik and clipped it to my target area with osmconvert. The GTFS file is obtained from https://gtfs.de/.

To Reproduce
Steps to reproduce the behavior:

import r5py

# Make the R5 transport network from these
transport_network = r5py.TransportNetwork(
    pbf_path,
    [gtfs_path],
)

Error message:

Traceback (most recent call last):
  File "c:\Users\johan\miniforge3\envs\r5py\Lib\site-packages\r5py\r5\transport_network.py", line 113, in __del__

The above exception was the direct cause of the following exception:

Expected behavior
I haven't used this r5py for a few months. Before this worked flawlessly and a transport network was created.

Environment:

• OS: Windows 11
• Python package source: mamba
• Versions of Python: 3.12
