great work. but getting pure black and white videos after running python run_nerf.py --config configs/lego.txt

[lithostark]

Hi, thank you for sharing the code!
After setting up following the instructions as
"git clone https://github.com/yenchenlin/nerf-pytorch.git
cd nerf-pytorch
pip install -r requirements.txt
bash download_example_data.sh" and training the network by
"python run_nerf.py --config configs/lego.txt"
I've got some .mp4 files under logs/blender_paper_lego/
But all the _disp.mp4 videos show pure black, and all the _rgb.mp4 videos show pure white. Is there any steps missing?
I need some help here.

I encountered the same issue as you, but I followed the author's suggestion to download the pre-trained model and used the command
python run_nerf.py --config configs/lego.txt --render_only --ft_path path/to/your/model.tar
and obtained the expected results. I suspect this is related to the trained model.
Hope this helps you.
