ViTDet

Description

This is an implementation of ViTDet based on MMDetection, MMCV, and MMEngine.

Usage

Training commands

Follow original setting, this project is trained with total batch size of 64 (16 GPU with 4 images per GPU).

In MMDetection's root directory, run the following command to train the model:

GPUS=${GPUS} ./tools/slurm_train.sh ${PARTITION} ${JOB_NAME} ${CONFIG_FILE} ${WORK_DIR}

Below is an example of using 16 GPUs to train VitDet on a Slurm partition named dev, and set the work-dir to some shared file systems.

GPUS=16 ./tools/slurm_train.sh dev vitdet_mask_b projects/ViTDet/configs/vitdet_mask-rcnn_vit-b-mae_lsj-100e.py /nfs/xxxx/vitdet_mask-rcnn_vit-b-mae_lsj-100e

Testing commands

In MMDetection's root directory, run the following command to test the model:

python tools/test.py projects/ViTDet/configs/vitdet_mask-rcnn_vit-b-mae_lsj-100e.py ${CHECKPOINT_PATH}

Results

Based on mmdetection, this project almost aligns the test and train accuracy of the ViTDet.

Note:

  1. The mask AP is lower than official repo slightly
  2. other model vision will release code and weights in the future
