Hi, |
|
Hello, back here. Using sumo, matlab r2019b and osx big sur. I have this issue when running the traci4matlab example: @slavi-czech in my case, the java classpath file has txt extension. I tried to deactivate the osx firewall, with no chance. What to do? Any idea? |
Same problem happened to me. I am using MATLAB 2022 and sumo 1.11.0 on MacBook Pro M1 Pro. Any idea to solve this issue? Thanks! |
|
actually yes, it was also pretty easy: running matlab from terminal via sudo should solve the issue. |
Thank you for the update Davide. I have tried assigning "root" to my MATLAB license and running the matlab script from terminal using sudo. However the same error message pop up in my terminal window. Do you have the same issue? If so, could you please provide more details of solving it? Thanks! |
|
I used to have this issue but running "sudo open /Applications/MATLAB/R2019b.app" worked in my case. I don't have further suggestions, sorry :/ |
It works for me, Thanks! |
|
Hello, I have the same error on my Ubuntu machine. I checked my javaclasspath extension that is fine. Thank you |
I installed the traci4matlab and the traci_test.m run successful. But run the inter_palmas_actuated.m ,the sumo log displays follows:
Loading configuration... done.

how can i do for it?
And i also run my own od2trips.m , the m-files as follows:
clear
close all
clc
import traci.constants
scenarioPath = 'D:\Program Files\matlab\R2017b\toolbox\traci4matlab\traci4matlab\examples\od2trips\shengzhen.sumocfg ';
system(['sumo-gui -c ' '"' scenarioPath '"' ' --remote-port 8813--start&']);
traci.init();
the matlab log displays :
