Ggis - qaequilibraE: python error when Network Preparation

[Ruoyun Chen]

Hi I've been using Qgis on Mac M1 pro and I want to use Aequilibrae to prepare for the traffic network, which work perfectly well before when I use my old MAC. 

However I have this error (attached below). Could you please suggest me what to do? I have been checking gcc --version and it shows:

Apple clang version 13.1.6 (clang-1316.0.21.2.5)

Then I do: 

brew install gcc@12

But it does not help. Can you please suggest what should I do to make use of the Network Preparation function of qaequilibrae?

Thanks for your time!

Hi Ruoyun,

AequilibraE does not currently support the M1 chip, as none of the developers working on it has an M1 chip and we don't have the budget to implement testing and CI for it.

Hopefully there will be someone interested in funding that work (and ongoing expense for CI outside Github) soon or GitHub will make the feature available for free.

For now, your best bet is to clone AequilibraE and build it locally.

Cheers,

Pedro

Clone and build isn't an obvious set of steps unfortunately:

This is the shortest version for compiling that i'd recommend (taken
from the github ci scripts)

python -m pip install virtualenv
python -m virtualenv venv
. venv/bin/activate
python -m pip install --upgrade pip setuptools wheel twine
python -m pip install -r requirements.txt
python -m pip install -r requirements_additional.txt
python setup.py sdist bdist_wheel

Hi Kai Tang,

                 Unfortunately I won't be able to analyze your code, as that takes a substantial amount of time, especially when it is custom code that in a non-standard way of using AequilibraE.

I would recommend you create a small example that is easy to replicate, as that makes it possible to our volunteer developers to look into it.

Cheers,

Pedro

Hi Pedro,

    I update the source code from link , which lacks several compiled files，I find them in the  V0.9.3   packages（ipf_core.cp37-win_amd64.pyd，AoN.cp37-win_amd64.pyd).

   But I found there is still some problems with the select-link results. In the nanshan project，I choose the 211839 link to do select-link analysis：

the select-result ：

the code project is below

Regards,

Kai Tang
