ran command for stage2:
python launch.py --config custom/threestudio-dreamcraft3D/configs/dreamcraft3d-geometry.yaml --train system.prompt_processor.prompt="a cartoon boy king in robotic knight armor" data.image_path="./load/images/rey_rgba.png" system.geometry_convert_from="./outputs/dreamcraft3d-coarse-n
eus/a_cartoon_boy_king_in_robotic_knight_armor@20240302-113207/ckpts/last.ckpt"

i get this error and dont understand why . any help resolving this ?

seems the issue was something in the threestudio extension version. i installed in its own env from this repo and it was able to get stage 2 to train.
