2. 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

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）：
