环境

Pytorch 1.10.1
Python 3.8
Cuda 11.1

2 安装PyTorchVideo

cd /home
git clone https://gitee.com/YFwinston/pytorchvideo.git
cd pytorchvideo
pip install -e .

apt update
apt install libgl1-mesa-glx -y

3 安装yolov5-slowfast-deepsort-PytorchVideo

3.1 下载yolov5-slowfast-deepsort-PytorchVideo

使用gitee（推荐）

cd /home
git clone https://gitee.com/YFwinston/yolov5-slowfast-deepsort-PytorchVideo.git

3.2 安装

cd /home/yolov5-slowfast-deepsort-PytorchVideo
pip install -r requirements2.txt

3.3 下载文件

[yolov5_file]
[slowfast_file]

我是将ckpt.t7放在了：/user-data/yolov5_file/
我是将SLOWFAST_8x8_R50_DETECTION.pyth放在了：/user-data/slowfast_file/
我是将yolov5l6.pt放在了：/user-data/yolov5_file/
我是将yolov5-master.zip放在了：/user-data/yolov5_file/

mkdir -p /home/yolov5-slowfast-deepsort-PytorchVideo/deep_sort/deep_sort/deep/checkpoint/
cp /user-data/yolov5_file/ckpt.t7 /home/yolov5-slowfast-deepsort-PytorchVideo/deep_sort/deep_sort/deep/checkpoint/ckpt.t7

mkdir -p /root/.cache/torch/hub/checkpoints/ 
cp /user-data/slowfast_file/SLOWFAST_8x8_R50_DETECTION.pyth /root/.cache/torch/hub/checkpoints/SLOWFAST_8x8_R50_DETECTION.pyth

cp /user-data/yolov5_file/yolov5l6.pt /home/yolov5-slowfast-deepsort-PytorchVideo/yolov5l6.pt

cp /user-data/yolov5_file/yolov5-master.zip /root/.cache/torch/hub/master.zip

3.4 测试

我将1.mp4存放在了/home/yolov5-slowfast-deepsort-PytorchVideo/demo/中

cd /home/yolov5-slowfast-deepsort-PytorchVideo
mkdir demo

cd /home/yolov5-slowfast-deepsort-PytorchVideo
python yolo_slowfast.py --input ./demo/1.mp4
