RuntimeError: The size of tensor a (50) must match the size of tensor b (10) at non-singleton dimension 1 #25

I change the frames from 50 to 10, and run the following command:
python main.py -y config/waymo-1006.yaml -p 'Remove all cars.Viewpoints ahead slowly and A chevrolet driving away from me fast.' -s demo

I got the following output:

This won‘t happen if I set frames as 50.
I think there's a hardcode remains, but I failed to find it.
Do you know how to generate a video with a different frame number? Many thanks!

Sorry, that shouldn't happen. We will check it immediately.

Very sorry for the late reply, we had a hard time rushing another DDL days before.

The reason for this problem is that we are not emptying the rendered image, and scene.current_images is read from the same folder. When you first render 50 frames and then switch to 10 frames, the output folder remains with 40 images rendered in the previous.

We fix this problem in these lines by cleaning the rendered folder. Sorry again for being late.

Cool, I successfully generated the video.Really appreciate your reply!
By the way, are you considering other alternative LLM models to be the agents，gpt4 api is a little bit expensive in such multi-agent collaborate system.

[yifanlu0227]

Great suggestion! We'll add it to the to-do list :)

@nevergone123 Hi, you can use many free LLM inference provided by NVIDIA.
