Performance

DatasetHandler leverages multiprocessing to significantly enhance performance by utilizing multiple CPU cores. This parallel processing capability ensures faster execution of time-consuming tasks, making the tool efficient for handling large datasets.

Key Areas Utilizing Multiprocessing:

• Downloading Files: The download_multiprocess function employs multiple processes to download files concurrently, reducing the time required to fetch large datasets from the internet.
• Unarchiving Files: The unarchive_multiprocess function unpacks multiple archive files simultaneously, speeding up the extraction process of downloaded data.
• Extracting Images from Videos: The extract_multiprocess function processes multiple video files in parallel to extract frames, which is especially useful for large collections of video data.

By parallelizing these tasks, DatasetHandler ensures that data preparation steps are performed efficiently, saving valuable time and computational resources.
