Docker Support (Early Stage)

docker pull wcwcw/smplerx_inference:v0.2
docker run  --gpus all -v <vid_input_folder>:/smplerx_inference/vid_input \

Inference

cd main
sh slurm_inference.sh {VIDEO_FILE} {FORMAT} {FPS} {PRETRAINED_CKPT} 

# For inferencing test_video.mp4 (24FPS) with smpler_x_h32
sh slurm_inference.sh test_video mp4 24 smpler_x_h32

2D Smplx Overlay

We provide a lightweight visualization script for mesh overlay based on pyrender.

cd main && python render.py \ --data_path {SMPLERX INFERENCE DIR} --seq {VIDEO NAME} \ --image_path {SMPLERX INFERENCE DIR}/{VIDEO NAME} \ --render_biggest_person False


## Training
```bash
cd main
sh slurm_train.sh {JOB_NAME} {NUM_GPU} {CONFIG_FILE}

# For training SMPLer-X-H32 with 16 GPUS
sh slurm_train.sh smpler_x_h32 16 config_smpler_x_h32.py

Testing

# To eval the model ../output/{TRAIN_OUTPUT_DIR}/model_dump/snapshot_{CKPT_ID}.pth.tar 
# with confing ../output/{TRAIN_OUTPUT_DIR}/code/config_base.py
cd main
sh slurm_test.sh {JOB_NAME} {NUM_GPU} {TRAIN_OUTPUT_DIR} {CKPT_ID}
