1、Kinetics-400数据集简介Kinetics-400是一个大型高质量的YouTube视频网站数据集，其中包含了各种各样的以人为中心的行为。 此数据集包含400个人类动作类，每个动作至少有400个视频剪辑。 每个剪辑持续约10秒，取自不同的YouTube视频。 这些动作以人为本，涵盖广泛的类别，包括演奏乐器的人与物体的交互、握手的人与人的交互等。

注：对于windows用户：由于需要cat和tar命令，请确保安装了git bash。 如果没有安装，可以下载到https://gitforwindows.org/安装。
文件下载过程
下载标签和原始部件文件。 标签存储标签信息，而原始部件存储视频被阻止的文件。
在git bash命令行中进入原始部件目录，然后执行以下操作：
cat compress.tar.gz.* compress.tar.gztarzxvfcompress.tar.gz包含名为compress的目录中的所有视频文件；
此版本的kinetics数据集是压缩版本，包含234619培训集and 19761验证集，目前未提供。 (test数据本身也没有网格真标签。 视频的大小为保证高度256像素，宽度遵循原始长宽比scale。
下载后，compress包含两个目录： train_256和val_256:
在这个目录中可以直接分开train和val两个部分。 此处的所有标记label/train _ 256.CSV label/val _ 256.CSV部分都是取自deepmind的原始标记label/kinetics-400_train
另外，在训练数据中，文件名的后缀带有时间信息。 例如，z2kMVJWpGxU_000038_000048.mp4。 小心！ 标记文件仅包含文件前缀(例如：z2kMVJWpGxU )。 请确定“标记前缀”是否与“文件名的前11位字符串”匹配。 这里所有的youtube_id都是11位。
