Windows path issue

[BarfingLemurs]

This is working great on windows with novel view synthesis, but there is an small path issue with 3d reconstruction:

Loading model from ../zero123/105000.ckpt

LatentDiffusion: Running in eps-prediction mode
DiffusionWrapper has 859.53 M params.
Keeping EMAs of 688.

@basilevh could you please look into this? I'm not familiar with directories on Windows.

The apostrophes (') look a bit out of place, could you retry without? Actually, I think Windows only accepts the double quotation mark " for paths (whereas Linux probably accepts both), so these two commands should both work (I think):

python run_zero123.py \
    --scene pikachu \
    --index 0 \
    --n_steps 10000 \
    --lr 0.05 \
    --sd.scale 100.0 \
    --emptiness_weight 0 \
    --depth_smooth_weight 10000. \
    --near_view_weight 10000. \
    --train_view True \
    --prefix experiments/exp_wild \
    --vox.blend_bg_texture False \
    --nerf_path data/nerf_wild

or

python run_zero123.py \
    --scene pikachu \
    --index 0 \
    --n_steps 10000 \
    --lr 0.05 \
    --sd.scale 100.0 \
    --emptiness_weight 0 \
    --depth_smooth_weight 10000. \
    --near_view_weight 10000. \
    --train_view True \
    --prefix "experiments/exp_wild" \
    --vox.blend_bg_texture False \
    --nerf_path "data/nerf_wild"

Hope this helps!

Edit: I've updated the readme to reflect this too.

python run_zero123.py --scene pikachu --index 0 --n_steps 10000 --lr 0.05 --sd.scale 100.0 --emptiness_weight 0 --depth_smooth_weight 10000. --near_view_weight 10000. --train_view True --prefix experiments/exp_wild --vox.blend_bg_texture False --nerf_path data/nerf_wild

Thank you, I used the first option and it works.
