• ADer is an open source visual Anomaly Detection toolbox based on PyTorch, which supports multiple popular AD datasets and approaches.
  
• We reproduce popular AD method under the Multi-class Unsupervised Anomaly Detection (MUAD) by default.
  
• We hope it can bring convenience to your research and application.

🛠️ Getting Started

Installation

• Clone this repo:

  git clone https://github.com/zhangzjn/ader.git && cd ader

• Prepare general experimental environment

  pip3 install timm==0.8.15dev0 mmselfsup pandas transformers openpyxl imgaug numba numpy tensorboard fvcore accimage Ninja
  pip3 install mmdet==2.25.3
  pip3 install --upgrade protobuf==3.20.1 scikit-image faiss-gpu
  pip3 install torch==2.1.2 torchvision==0.16.2 torchaudio==2.1.2 --index-url https://download.pytorch.org/whl/cu118
  (or) conda install pytorch==2.1.2 torchvision==0.16.2 torchaudio==2.1.2 pytorch-cuda=11.8 -c pytorch -c nvidia

Dataset Preparation

Please refer to Datasets Description for preparing visual AD datasets as needed.

• Real-IAD: A new large-scale challenging industrial AD dataset, containing 30 classes with totally 151,050 images; 2,000∼5,000 resolution; 0.01%6.75% defect proportions; 1:11:10 defect ratio.
• COCO-AD: Large-scale and general-purpose challenging AD-adapted dataset.
• MVTec AD: Most popular AD dataset.
• VisA: Popular AD dataset.
• Uni-Medical: Unified medical AD dataset.
• (Opt.) MVTec 3D-AD: Improved 3D version of MVTec AD.
• (Opt.) Cifar10 & Cifar100: For one-class-train, one-class-test, and unified settings.

Train (Multi-class Unsupervised AD setting by default, MUAD)

• Check data and model settings for the config file configs/METHOD/METHOD_CFG.py
• Train with single GPU example: CUDA_VISIBLE_DEVICES=0 python run.py -c configs/METHOD/METHOD_cfg.py -m train
• Train with multiple GPUs (DDP) in one node:
  • export nproc_per_node=8
  • export nnodes=1
  • export node_rank=0
  • export master_addr=YOUR_MACHINE_ADDRESS
  • export master_port=12315
  • python -m torch.distributed.launch --nproc_per_node=$nproc_per_node --nnodes=$nnodes --node_rank=$node_rank --master_addr=$master_addr --master_port=$master_port --use_env run.py -c configs/METHOD/METHOD_CFG.py -m train.
• Modify trainer.resume_dir to resume training.
• Single-class Unsupervised AD (SUAD, not recommend currently)
  1. one GPU-0 for training one grid class in mvtec dataset: CUDA_VISIBLE_DEVICES=0 python3 run.py -c configs/vitad/single_cls/vitad_mvtec_bs16.py -m train data.cls_names=grid trainer.checkpoint=runs/vitad/single_class/vitad_mvtec_bs16/grid
  2. one GPU-0 for training all classes serially in mvtec dataset: python3 runs_single_class.py -d mvtec -c configs/vitad/single_cls/vitad_mvtec_bs16.py -n 1 -m -1 -g 0
  3. $GPU_NUM GPUs for training all classes parallelly in mvtec dataset:: python3 runs_single_class.py -d mvtec -c configs/vitad/single_cls/vitad_mvtec_bs16.py -n $GPU_NUM -m 1
  4. results will be saved in default dir: runs/vitad/single_cls/vitad_mvtec_bs16

Test

• Modify trainer.resume_dir or model.kwargs['checkpoint_path']
• Test with single GPU example: CUDA_VISIBLE_DEVICES=0 python run.py -c configs/METHOD/METHOD_cfg.py -m test
• Test with multiple GPUs (DDP) in one node: python -m torch.distributed.launch --nproc_per_node=$nproc_per_node --nnodes=$nnodes --node_rank=$node_rank --master_addr=$master_addr --master_port=$master_port --use_env run.py -c configs/METHOD/METHOD_CFG.py -m test.

How to Build a Custom Approach

1. Add a model config cfg_model_MODEL_NAME to configs/__base__
2. Add configs to configs/MODEL_NAME/CFG.py for training and testing.
3. Add a model implementation file model/MODEL_NAME.py
4. Add a trainer implementation file trainer/MODEL_NAME_trainer.py
5. (Optional) Add specific files to data, loss, optim, etc.
