Waymo example: Render 3D does not work

[abastola0]

I followed the documentation for running the waymo example. The 2D rendering works with --render 2D but I'm getting errors in --render 3D with these lines:

python -m scenarionet.sim -d /path/to/exp_converted/ --render 3D

and python -m scenarionet.sim -d /path/to/exp_converted/ --render advanced

I'm getting this error:

I also tried the advanced version with Panda3D rendering but that also does not work. I tested the Pandas3D independently and it just works fine. The metadrive simulator also works fine.

Could you pull the latest MetaDrive and try again? I merged a PR for fixing this

[abastola0]

Yeah it works now. Thanks.

Hi Mr.Li:
I think this problem still exists under windows. My collegue pull the 4.2.3 Metadrive under Ubuntu and it worked. But I pull the 4.2.3 Metadrive under windows and failed. The error is " ValueError: too many values to unpack (expected 2)"

I recreated a new environment and installed everything from github. It works fine on my Windows machine.

Please make sure you install everything from github and pull the latest main.
