安装教程
首先参考官方安装必须的包并下载项目文件：https://github.com/facebookresearch/SlowFast/blob/main/INSTALL.md
安装注意：
- 最好使用Linux系统，如果是windows系统，请注意Vsual Studio的版本和CUDA的版本要对应，否则有些东西无法编译。
- 教程的最后一步先不要管：
运行前的准备
1.下载权重文件 ‘SLOWFAST_32x2_R101_50_50.pkl’
在终端输入下面的命令下载：
wget https://dl.fbaipublicfiles.com/pyslowfast/model_zoo/ava/SLOWFAST_32x2_R101_50_50_v2.1.pkl
下载后放到 AVA 目录下：
2.在AVA目录下新建ava.json标注文件，如上图
ava.json内容如下：

3.更改配置文件
在目录中找到 SLOWFAST_32x2_R101_50_50.yaml 文件
更改的内容如下：
其中 INPUT_VIDEO 和 OUTPUT_FILE需要自己添加。
INPUT_VIDEO 是要输入进行检测的视频。OUTPUT_FILE是检测后保存的检测结果。
路径都推荐用绝对路径。
WEBCAM要改成-1，默认为0，读取本地摄像头。
运行
运行命令(配置文件请替换成自己的路径)：
python run_net.py --cfg /root/autodl-tmp/slowfast/demo/AVA/SLOWFAST_32x2_R101_50_50.yaml
运行成功（请忽略user warning）：
视频检测结果：
