# you might need to adjust $CUDAROOT in ./install.sh
# to match your cuda config. default /usr/local/cuda
./install.sh# activate the miniconda venv
. ./env.sh
# download trained model
# Model: HalfResNet34
# Trained with Loss: Large margin arc distance
# Trained on: VoxCeleb1 & 2
# Test EER on vox1-O: `1.20 %`
