Hello

I start to use ORS library in Python to generate some optimization in VRP problem. Rigth now I am doing it using the ORS´s API but I would like to do it locally. Is there a way that I can install both software (ORS and VROOM) locally in order to generate optimization locally?

Best regards,  
Orlando

Hey,

yes, both are open source 🙂  
Find the ors installation instructions [here](https://giscience.github.io/openrouteservice/installation/Installation-and-Usage.html) and the VROOM installation instructions [here](https://github.com/VROOM-Project/vroom/wiki/Building). Note that for vroom you might want to use [vroom-express](https://github.com/VROOM-Project/vroom-express) to use it with http queries.

Best regards

Hello jschnell

Great. Thank you!. My second doubt is if I install both locally, Am I will be able to run my code of optimization in Python as usual?

Best regard,  
Orlando

Hey,

as I don’t know what your “usual” way of running optimization from python is, I don’t know 😉  
Using vroom-express, you should be able to query your local installation as you do with the ORS API.

Best regards
