When I run python main.py -y config/3dgs-waymo-1137.yaml -p "Add a Benz G in front of me, driving away fast.". I meet this error.

start rendering in parallel, process number is 1.
This may take a few minutes. To speed up the foreground rendering, you can lower the `frames` number or render not-wide images.
If you find the results are incomplete or missing, that may due to OOM. You can reduce the multi_process_num in config yaml.
You can also check the log file for debugging with `save_cache` enabled in the yaml.

Then I check 1137_demo_2024_12_04_18_49_56/rendering_log/0.txt:

How can I deal with this error.Thank you very much.

[obk0515]

I solved this error.
The correct path is data/blender_assets/assets/Benz_G.blend
So we need to modify it in the config/***.yaml.
