SYSU-HCP-at-ImageCLEF-VQA-Med-2021

Main requirements

• torch == 1.4.0
• torchvision == 0.5.0
• tensorboardX == 2.1
• Python 3

The environment can be created following this:

# First, create a virtual environment
conda create -n your_env_name python=3.6
conda activate your_env_name

# Second, install the required packages from requirements.txt
conda install pip
pip install -r requirements.txt

Models

The ResNeSt needs to be installed before using.

Datasets

The training set, validation set and test set can be downloaded from the Google Drive directly and should be put in the data folder.

Training

You can train the model from scratch. The command and corresponding parameters are as follows:

python train.py [-input_size <int>] [-batch_size <int>] [-backbone <model_name>] [-train_set <Med_LT_train or train>] [-gpu <int>] [-world_size <int>] [-port <int>] [--mixup] [--label_smooth] [--superloss] [-dryrun] [-resume_path <checkpoint.pth>] [-pretrain <checkpoint.pth>]

Evaluation

You can evaluate the trained model and save the results in a csv file.

python validation.py -model_path <checkpoint.pth> -csv_path <path_to_save_evaluation_results> [-input_size <int>] [-backbone <model>] [-gpu <int>]

Pretrained models for VQA-Med 2021

We provide the pretrained models for VQA-Med 2021 in Google Drive and Baidu Cloud (code:i1nn).

After downloading the models, you can get the result by the following command:

python inference_ensemble_once.py
