  • Thread-topic: Error Message: Could not connect to TraCI server

Hello Anna-Lena,


TraCI uses the TCP/IP protocol. Can you check if the Firewall of the Linux server is blockin TraCi?

Betreff: [sumo-user] Error Message: Could not connect to TraCI server
 

Dear all,

 

I created a Sumo simulation with some Python code to evaluate an ego vehicle in several scenarios. The code can be executed without any errors on my local PCs (Windows). When running on a high-performance server (Linux), I get this error message at random:

 

 

However, there are also runs in which the code succeeds (with the same scenarios and the same seed).

 

What does this error mean and why does it occur randomly? How can I fix it?

 

 

I would very much appreciate any clarifications.

 

 

Thanks and best regards,

 

Anna-Lena
