依据https://github.com/wzmsltw/BSN-boundary-sensitive-network说明，从百度云下载好了特征数据

得到如图几个文件

进入到文件目录，执行（ * 就是 *，不要像我一样把 *替换成01、…、05，执行了5次。。 ）

cat zip_csv_mean_100.z* > csv_mean_100.zip

然后会生成一个新的文件csv_mean_100.zip，接着执行（后来发现直接执行下面的命令即可。。和前面的cat命令似乎没关系，cat之后生成的csv_mean_100.zip似乎是有问题，导致无法解压）

7z x zip_csv_mean_100.zip

解压成功，得到文件夹csv_mean_100，其中包含19228个csv文件，将该文件夹放至./data/activitynet_feature_cuhk/即可

试错过程：

因为发现zip_csv_mean_100.zip可以直接点开（可能是在执行cat命令之后），并打开其中的csv文件。所以一定有方法将内容提取出来。尝试了各种解压方法，分别对两个zip文件解压，只有上面的命令成功。其余命令不知所“错”。

首先尝试

unzip csv_mean_100.zip

报错：

尝试：

unzip zip_csv_mean_100.zip

仍然报错：

尝试jar xvf csv_mean_100.zip 以及jar xvf zip_csv_mean_100.zip。报错：

xvf zip_csv_mean_100.zip

尝试7z x csv_mean_100.zip ，报错：
