The UCF101 dataset contains 101 action categories, such as Basketball shooting, playing guitar, and Surfing. We can download the dataset from http://crcv.ucf.edu/data/UCF101.php.

On the website, you need to download the UCF101 dataset in the file named UCF101.rar, and the train/test splits for action recognition in the file named UCF101TrainTestSplits-RecognitionTask.zip. You need to extract the dataset before moving to the next section, where we will perform a pre-processing technique on videos before training.
