Sanfrancisco map exists a problem with SORA-SVL on Windows 10 version

[meng2180]

Hello， I have tested the SanFrancisco_correct map, but the issue happened when simulating it on Windows 10 version. Particularly, from the beginning of the simulation (or even after clicking Start), LGSVL on Windows only showed EV with gradient background, and without any objects such as buildings, roads.

-SVL OS：Windows 10

• Apollo OS: Ubuntu
• Version of SVL 2021.03

DreamView seems to be normal, but there still exists a problem with LGSVL, no matter whether I modify the time in LGSVL.

Hi @meng2180 , thanks for posting the issue!

I am not sure what is going on with your specific case and I am unable to diagnose this problem at this moment.
I have been using https://github.com/MingfeiCheng/AV-Fuzzer and I believe he is also using SanFrancisco_correct. I haven't run into problems running this implementation of AV-Fuzzer.

Thanks for your reply! I just used a simple code to run the SanFrancisco_correct map (OS：Windows 10), below is the code I run (I run the same code on Ubuntu and the lgsvl works fine) :

Hi @meng2180 .
Looks like you are using the right map id. Unfortunately, I am not sure about how to deal with this because I didn't run into this problem. I have been using Ubuntu but I don't know why it wouldn't work on Windows.
