Preparation

1. Prepare datasets folder

├── datasets
│   ├── public_test
│   └── vehicle_models
└── MCS2022.CarVerification
    ├── <all_sources>
    ├── checkpoints
    ├── database
    └── logs

2. Install requirements.txt (tested for python3.6):

pip install -r requirements.txt

Train

cd MCS2022.CarVerification
python train.py

Generate database

Change PRETRAIN variable inside generate_database.py

cd MCS2022.CarVerification
python generate_database.py

Inference

Use scripts/ckpt_to_model.py to convert checkpoints to model weights.

Change filenames inside make_submit.py

cd MCS2022.CarVerification
python make_submit.py
