Networks fail to download in notebook 01

[Froguin99]

Hi all,

Using a completely fresh clone of the repo and fresh install of the enviroment, I cannot pass the first script! Error occurs duing the "Networks" section of the data download/wrangle. I've included the terminal output below. These are the versions of python/key libs that are downloaded when starting from scratch:

Python implementation: CPython
Python version : 3.12.6
IPython version : 8.27.0

pandas : 2.2.2
osmnx : 1.9.4
networkx : 3.3
shapely : 2.0.6
fiona : 1.10.1
matplotlib: 3.8.4
numpy : 1.26.4
geopandas : 0.14.4

These seem to match which what I would expect given what's in the enviroment file, so not quite sure where the issue lies.

If there is anything else I can provide please let me know!

Full error output is as follows:

Should add that I haven't touched anything with the parameters or anything else etc. This is straight after cloning and setting up the enviroment. Working with the default Lyon and Paris cities.

Thx! Could you check if it was this issue? geopandas/geopandas#1887 (comment)
Please let me know in any case (whether this was the issue or not)

[Froguin99]

Took a deeper look and managed to get passed this issue. Not entirely sure why, but if you install using miniforge and mamba rather than with conda and the anaconda prompt, we don't get this issue.

I did try and solve the issue which arises from installing via conda but haven't got it sorted yet. It does seem related to this issue.

Given mamba works (and is open, opposed to conda!), it's probably not worth digging much deeper 👍

[mszell]

Without having looked into it yet, I agree that conda might be the problem. We will still need to update the readme, so this was still very useful, thx. Will keep it open until fixed.

If you run into other problems please create more github issues - so we can make this code run for as many people as possible.
