oh, that’s a helpful bit of information.  I was doing a couple things wrong with my dataloader and one of them seems to be that I was trying to focus attention on placing the data onto the GPU while inside the dataloader.  I was also generating all the images within the dataloader as well.  So, I’m restructuring to generate a custom dataset where the images will be constructed, and my understanding now is that the dataloader will pull from the custom dataset, allowing another batch of image data to be built while the network is processing what the dataloader has just provided.
