What Causes Slow Data Preprocessing In PyTorch For Large Datasets? Have you ever wondered why data preprocessing can slow down when working with large datasets in PyTorch? In this informative video, we'll explain the common causes of slow data loading and how to improve your data pipeline for faster training. We'll start by discussing how the default data loading process works and why it can become a bottleneck. You'll learn how increasing the number of worker processes can enable parallel data loading, ensuring your GPU stays busy. We’ll also cover how complex transformations and data augmentations on the fly can impact speed, and what strategies you can use to optimize these operations. Additionally, we'll explain the importance of data transfer between CPU and GPU, and how enabling pinned memory can significantly reduce transfer delays. The video also highlights how slow storage options and inefficient data formats can contribute to delays, along with tips for using faster drives and caching data. Finally, you'll discover how to set up your data pipeline to load data asynchronously during training, preventing GPU idleness and boosting overall efficiency. Whether you're training large models or working with big datasets, these tips will help you streamline your data preprocessing process for quicker, more effective training sessions.
