Describe the bug

If you install following these steps here: https://mmaction2.readthedocs.io/en/latest/get_started/installation.html

You won't be able to run the demos, eg.:

(openmmlab) $ python demo/webcam_demo_spatiotemporal_det.py \
    --input-video 0 \
    --config configs/detection/slowonly/slowonly_kinetics400-pretrained-r101_8xb16-8x8x1-20e_ava21-rgb.py \
    --checkpoint https://download.openmmlab.com/mmaction/detection/ava/slowonly_omnisource_pretrained_r101_8x8x1_20e_ava_rgb/slowonly_omnisource_pretrained_r101_8x8x1_20e_ava_rgb_20201217-16378594.pth \
    --det-config demo/demo_configs/faster-rcnn_r50_fpn_2x_coco_infer.py \
    --det-checkpoint http://download.openmmlab.com/mmdetection/v2.0/faster_rcnn/faster_rcnn_r50_fpn_2x_coco/faster_rcnn_r50_fpn_2x_coco_bbox_mAP-0.384_20200504_210434-a5d8aa15.pth \
    --det-score-thr 0.9 \
    --action-score-thr 0.5 \
    --label-map tools/data/ava/label_map.txt \
    --predict-stepsize 40 \
    --output-fps 20 \
    --show

is this repo still alive? It seems like the last time a commit was actually merged in was 2 years ago. Interested in building / collaborating on this, but not if its moved to a new home.
