The dataset viewer is not available because its heuristics could not detect any supported data files. You can try uploading some data files, or configuring the data files location manually.

NFR sample training data
Sample data pack for NFR (Neural Face Rigging),
SIGGRAPH 2023. It covers the ICT_single_coarse dataset (40 identities) and is
meant to get the training pipeline running without downloading the full ~800GB
set used in the paper.
What is in here
Only the files that cannot be regenerated are shipped (3.0GB):
data/ICT_single_coarse/{train,val,test}/*_processed_matrix.pkl # 40 x 75MB, deformation gradients
data/ICT_single_coarse/*_neutral.obj # 40 neutral meshes
data/ICT_single_coarse/iden_exp_weights_single.npz # identity / expression coefficients
data/ICT_single_coarse/ICT_single_exp_weights.npy # per-expression weights
data/ICT_single_coarse/gradients_std.npy
data/ICT_live_100/gradients_std.npy # referenced by std_file
data/MF_all_v5/img_stat.pkl # referenced by img_file
Each _processed_matrix.pkl holds 266 expressions of one identity: verts
(266, 3694, 3) and gradients (266, 7007, 9).
Usage
Download and unpack at the repository root:
from huggingface_hub import snapshot_download
snapshot_download(repo_id="HKU-CGVU/NFR-sample-data", repo_type="dataset",
local_dir=".", allow_patterns="data/*")
allow_patterns="data/*" keeps this dataset card from landing on top of the
repository's own readme.md on case-insensitive filesystems (macOS, Windows).
Then regenerate the derived tensors (renders, DiffusionNet gradients and spectral decompositions):
python dataset_preprocess.py \
--data_dir ./data/ICT_single_coarse \
--save_data_dir ./data/ICT_single_coarse \
-pi -pg -pd --num_threads 8
This adds about 32GB and takes roughly 30 minutes. Then train:
python FWH_run.py -c config/train_single.yaml
Training this configuration needs about 24GB of RAM and a single GPU. See the Training section of the repository readme for details.
