How can I confirm I'm using GPU/CUDA?

Hey, (hoping to alleviate some qa from the dev)

Pretty sure the script is calculating the flow right now, check the directory where your script is and you should see forward and backward files showing what frame its on right now. Takes soooo long to do the deepflow calculations.

I see, thanks, however is there a way to determine whether GPU or CPU is being used? I assume it will be slow either way :)

the cudnn flag should make it use the gpu cudnn library. However, you'll have to look at the script to see if it checks for the cudnn library before it starts the flow calculations.

I like to comment out the part after the flow and make sure those files are done. Then afterwards I'll play with the stylize part. I like to do that to make sure the first few images look ok and see what the run times and memory bounds are of the gpu part, not to mention path issues with cudnn and whatnot.

edit: the nice part btw is that once the deepflow calculations are done, you can reuse them again for different styles
