Requirements

• Python 3
• CUDA
• numpy
• tqdm
• PyTorch (1.2)
• torchvision
  Recommend: the environment can be established by running

conda env create -f environment.yaml

Data preparation

1. Download the [i3d features]([link: https://pan.baidu.com/s/1Cn1BDw6EnjlMbBINkbxHSQ password: u4k6])(https://drive.google.com/file/d/193jToyF8F5rv1SCgRiy_zbW230OrVkuT/view?usp=sharing) and change the "dataset_path" to you/path/data

the dataset.tar file can be unzip by using tar -xvf dataset.tar

Visual Feature Extraction

if you want to extract Visual Feature like this project, you can clone this project([https://github.com/wanboyang/anomaly_feature])

Training

python main.py

The models and testing results will be created on ./ckpt and ./results respectively
