2. Download required Python packages:

The following packages are suitable for NVIDIA GeForce RTX A6000.

pip install torch==1.10.0+cu111 torchvision==0.11.0+cu111 torchaudio==0.10.0 -f https://download.pytorch.org/whl/torch_stable.html
pip install -r requirements.txt
pip install hub

If you want to use the docker environment, please download the docker image through the command below

docker pull sgkang0305/vlcounter

3. Download CLIP weight and Byte pair encoding (BPE) file

Please download the CLIP pretrained weight and locate the file under the "pretrain" folder.

Please download the BPE file and locate the file under the "tools/dataset" folder.

Run the Code

Train

You can train the model using the following command. Make sure to check the options on the train.sh file.

bash scripts/train.sh FSC {gpu_id} {exp_number}

Evaluation

You can test the performance of trained ckpt with the following command. Make sure to check the options in the test.sh file. Especially '--ckpt_used' to specify the specific weight file.

bash scripts/test.sh FSC {gpu_id} {exp_number}

We provide a pre-trained ckpt of our full model, which has similar quantitative result as presented in the paper.

FSC val MAE	FSC val RMSE	FSC test MAE	FSC test RMSE
18.06	65.13	17.05	106.16

CARPK MAE	CARPK RMSE	PUCPR+ MAE	PUCPR+ RMSE
6.46	8.68	48.94	69.08
