Warning : DSMR Not found

[tersite1]

I build satnerf model with all dependencies cleared(I think) and ran the following commands:

python3 create_satnerf_dsm.py Sat-NeRF /home/lutetia/satnerf/pretrained_models/JAX_068 out_dsm_path/JAX_068 28 /home/lutetia/satnerf/pretrained_models/JAX_068 /home/lutetia/satngp/data/dataset/root_dir/crops_rpcs_ba_v2/JAX_068 /home/lutetia/satngp/data/dataset/DFC2019/Track3-RGB-crops/JAX_068 /home/lutetia/satngp/data/dataset/DFC2019/Track3-Truth

But the script says dsmr error, Altitude MAE: + NaN

is there anyone know the reason for this and solved before??
