Environments
This repo is tested on following environment:
- Ubuntu 20.04
- Python >= 3.7
- PyTorch == 1.10.1
- Cuda V11.3.109
Install
-
Follow
LAFAN1dataset's installation guide. You need to install git lfs first before cloning the dataset repo. -
Run LAFAN1's
evaluate.pyto unzip and validate it. (Installnumpyfirst if you don't have it)$ pip install numpy $ python ubisoft-laforge-animation-dataset/evaluate.py
With this, you will have unpacked LAFAN dataset under
ubisoft-laforge-animation-datasetfolder. -
Install appropriate
pytorchversion depending on your device(CPU/GPU), then install packages listed inrequirements.txt. .
