Prerequisites

• Linux or macOS
• Python 3
• PyTorch 1.7.0

Setup

The code can be run with Python 3.6 and above.

Install the required packages:

pip install -r requirements.txt

Clone this repo:

cd ASTNet/ASTNet

Data preparation

We evaluate ASTNet on:

• UCSD Ped2
• CUHK Avenue
• ShanghaiTech Campus

A dataset is a directory with the following structure:

$ tree data
ped2/avenue
├── training
│   └── frames
│       ├── ${video_1}$
│       │   ├── 000.jpg

Evaluation

Please first download the pre-trained model

Dataset	Pretrained Model
UCSD Ped2	github / drive
CUHK Avenue	github / drive
ShanghaiTech	github / drive

To evaluate a pretrained ASTNet on a dataset, run:

 python test.py \
    --cfg <path/to/config/file> \
    --model-file </path/to/pre-trained/model>

For example, to evaluate ASTNet on Ped2:

python test.py \
    --cfg config/ped2_wresnet.yaml \
    --model-file pretrained.ped2.pth

Training from scratch

To train ASTNet on a dataset, run:

python train.py \
    --cfg <path/to/config/file>

For example, to train ASTNet on Ped2:

python train.py \
    --cfg config/ped2_wresnet.yaml

Notes:

• To change other options, see <config/config_file.yaml>.
