about cached memory when running the code

[longyangqi]

Hi,
I have a question about the code.
When I train the model on KittiDataset, I find that the program puts a lot of data to the cached memory until the memory is full.
when i use "top" command in Terminal, I see that: (I use the exp=exp_guided_enc_dec)

Have you ever encountered this situation? Did you notice that? (Although it might not affect training? )
Many thanks!
