Question about method read_data_to_ram

[Yiwen Chen]

Thanks for your great work!
I really don't understand what is the below method used for and I haven't found it on the Internet. Could you please help me? Why this can load data to ram? Is this different from directly using self.image? Thanks!

Hi, self.image and self._image are two different variables. self._image is the actual storage of the data, self.image is an on-demand property.
In this code, we first call the property to read the image, and store in to self._image variable, so it is in the memory.

You can simplify it to

self._image = self.image
