Environments Settings

  • CUDA version >= 11.1

  • Pytorch version >= 1.8

  • Ubuntu 18.04

  • I trained the model using 4 Gpus (Rtx3090).


# create environment
$ conda create -n aiconnect python=3.9 -y
$ conda activate aiconnect

# install pytorch
$ conda install pytorch==1.8.0 torchvision==0.9.0 cudatoolkit=11.1 -c pytorch -c conda-forge

# install mmcv
$ pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.8.0/index.html

# install requirements
~/aiconnect_action$ bash install.sh

Data Preparation

# mp4를 제 폴더에 옮길 필요없이 server에 있는 mp4 folder path만 지정해주시면 됩니다.

# Extract train video frames
~/aiconnect_action$ python extract.py --dir={competition_train_mp4_folder_dir_path} --output-root=./data/train_raw_frame

# Extract test video frames
~/aiconnect_action$ python extract.py --dir={competition_test_mp4_folder_dir_path} --output-root=./data/test_raw_frame

# Generate train files for mmaction & mmdetection
~/aiconnect_action$ python preprocess.py

Inference & Post-processing & Generate final submission file

~/aiconnect_action$ bash inference.sh {number_of_gpu_to_use} # bash inference.sh 4

Training Script

  • I chose the best model1 & model2 & model3 models.
# train model1(classifier) & model2(classifier) & model3(detector)
~/aiconnect_action$ bash train.sh {number_of_gpu_to_use} # bash inference.sh 4

# or
cd mmaction2

# train model1
~/aiconnect_action/mmaction2$ bash tools/dist_train.sh configs/recognition/tsm/super_tsm_r50_modify.py 4 --work-dir data/results/model1 --validate --seed 0 --deterministic

# train model2
~/aiconnect_action/mmaction2$ bash tools/dist_train.sh configs/recognition/tsm/super_tsm_r50_modify_oversampling.py 4 --work-dir data/results/model2 --validate --seed 0 --deterministic

cd ..
cd mmdetection
# train model3
~/aiconnect_action/mmdetection$ bash tools/dist_train.sh configs/faster_rcnn/faster_rcnn_r50_fpn_1x_coco.py 4 --work-dir data/results/model3 --seed 0 --deterministic
