Pytorch memory pinning

WebFeb 16, 2024 · The purpose of this post is to show how to use multi-threading to parallelize data processing with data transfer from pageable to page-locked memory. I was motivated to examine this issue while looking at the effect of the pin_memory flag in PyTorch’s dataloader. Let me provide some background information first. Web"CUDA out of memory" 错误提示意味着你的显存不足以运行模型训练。可能的解决方法包括： 1. 减小批次大小 - 将数据集分成更小的一部分，以便能够适应显存。你可以逐渐递增批次大小，直到你达到内存限制。 2. 减小模型大小 - 减小模型的大小可能会降低内存需求。
