text: Title: The problem of style transfer
  Body: Hello, author. 
  I want to use my own dataset to perform some style transfer tasks, such as converting land scenes into an underwater style. However, I only want to transfer the style. But when I was running my own dataset, I found that besides the style being transferred, the scenery in the pictures also changes (perhaps because the scenery in the land photos is different from that at the bottom of the water). How can I keep the scenery in the pictures unchanged while making the environment look like it's underwater?
