Requirements

Installation

pip install -r requirements.txt
(Python version is the 3.7 and the GPU is the V100 with cuda 10.1, cudatoolkit 10.1)

Prepare Datasets

Download the UDA datasets Office-31, Office-Home, VisDA-2017, DomainNet

Then unzip them and rename them under the directory like follow: (Note that each dataset folder needs to make sure that it contains the txt file that contain the path and lable of the picture, which is already in data/the_dataset of this project. The 'Real World' domain directory name of the Office-Home should be renamed to 'Real_World' for dataset loading. Otherwise you may encounter "FileNotFoundError: [Errno 2] No such file or directory" )

│       └── *.txt 

Prepare DeiT-trained Models

For fair comparison in the pre-training data set, we use the DeiT parameter init our model based on ViT. You need to download the ImageNet pretrained transformer model : DeiT-Small, DeiT-Base and move them to the ./data/pretrainModel directory.

Training

We utilize 1 GPU for pre-training and 2 GPUs for UDA, each with 16G of memory.

Scripts.

Command input paradigm

bash scripts/[pretrain/uda]/[office31/officehome/visda/domainnet]/run_*.sh [deit_base/deit_small]

For example

DeiT-Base scripts

# Office-31     Source: Amazon   ->  Target: Dslr, Webcam
bash scripts/pretrain/office31/run_office_amazon.sh deit_base
bash scripts/uda/office31/run_office_amazon.sh deit_base

#Office-Home    Source: Art      ->  Target: Clipart, Product, Real_World
bash scripts/pretrain/officehome/run_officehome_Ar.sh deit_base
bash scripts/uda/officehome/run_officehome_Ar.sh deit_base

# VisDA-2017    Source: train    ->  Target: validation
bash scripts/pretrain/visda/run_visda.sh deit_base
bash scripts/uda/visda/run_visda.sh deit_base

# DomainNet     Source: Clipart  ->  Target: painting, quickdraw, real, sketch, infograph
bash scripts/pretrain/domainnet/run_domainnet_clp.sh deit_base
bash scripts/uda/domainnet/run_domainnet_clp.sh deit_base

DeiT-Small scripts Replace deit_base with deit_small to run DeiT-Small results. An example of training on office-31 is as follows:

# Office-31     Source: Amazon   ->  Target: Dslr, Webcam
bash scripts/pretrain/office31/run_office_amazon.sh deit_small
bash scripts/uda/office31/run_office_amazon.sh deit_small

Evaluation

# For example VisDA-2017
python test.py --config_file 'configs/uda.yml' MODEL.DEVICE_ID "('0')" TEST.WEIGHT "('../logs/uda/vit_base/visda/transformer_best_model.pth')" DATASETS.NAMES 'VisDA' DATASETS.NAMES2 'VisDA' OUTPUT_DIR '../logs/uda/vit_base/visda/' DATASETS.ROOT_TRAIN_DIR './data/visda/train/train_image_list.txt' DATASETS.ROOT_TRAIN_DIR2 './data/visda/train/train_image_list.txt' DATASETS.ROOT_TEST_DIR './data/visda/validation/valid_image_list.txt'
