this CUDA API is supposed to be very slow. There is cuda host caching allocator that will creates a memory pool to avoid calling this API. Can you make sure you run the data loader multiple times to warm up the cache? It should stop showing up after a while

I have already used data cache to speed up. it is very common in my model.
What is the size of pin_memory ๏ผDuring the training process, I saw that there was still a large amount of remaining GPU memory.
