Rendering after finetuning: index out of bounds

[cduguet]

I have finetuned using your indications for a blender lego scene:

CUDA_VISIBLE_DEVICES=0  python train_mvs_nerf_finetuning_pl.py  \
    --dataset_name blender --datadir /path/to/nerf_synthetic/lego \
    --expname lego-ft  --with_rgb_loss  --batch_size 1024  \
    --num_epochs 1 --imgScale_test 1.0 --white_bkgd  --pad 0 \
    --ckpt ./ckpts/mvsnerf-v0.tar --N_vis 1

Then using rendering on renderer-video.ipynb I get to the following error:

Found ckpts ['./runs_fine_tuning/lego-ft/ckpts/latest.tar']

     58             # neighboring views with position distance

IndexError: index 43 is out of bounds for axis 0 with size 16

Some more info while debugging:
