How to remove the memory problem?

[Aliktk]

Hello, sir thanks for the repo. I have done image preprocessing. Now I want to train the network but as the memory dumped in preprocessing but still, I have been done it. In training, the system hanged and RAM memory is full, I have 64GB ram with 50GB+ paging (virtual ram).
Do you have any idea how to tackle this error?
@thtang Thanks for your concern
