By default, freeing memory in CUDA is expensive because it does a GPU sync. Because of this, PyTorch avoids freeing and mallocing memory through CUDA, and tries to manage it itself. When blocks are freed, the allocator just keeps them in their own cache. The allocator can then use the free blocks in the cache when something else is allocated. But if these blocks are fragmented and there isn’t a large enough cache block and all GPU memory is already allocated, PyTorch has to free all the allocator cached blocks then allocate from CUDA, which is a slow process. This is what our program is getting blocked by. This situation might look familiar if you’ve taken an operating systems class.，更多细节参见新收录的资料

下文中，“2025年春节”、“2026年春节”既指代上述两个时间段。需要说明的是，由于农历、休假安排等原因，2026年春节的公休时间较2025年更长，例如春节假期2025年放假八天、2026年放假九天，春节时间也错开了半个月有余。春节所在时间、休假长短等都会对零售消费产生影响，数据仅供参考，不构成投资建议。。关于这个话题，新收录的资料提供了深入分析
