Creating an H5 file for training? How?

[alwyz]

I'm pretty new to all of this, and have been having a hard time understanding how to create the kind of h5 file I want for my project. I have, what seems to me, to be a very simple project. I have black and white footage of a music concert, and color photos of that same concert. I want to train torch on the color photos. I've already colorized the footage with torch and your script, but I think the results could be better with color images of the actual subject matter. What do you advise?
