raise IndexError

Hello, thanks for your impressive work!
When I run your code to reproduce the work, I met the following errors:

I used aflw datasets as your example mentined, it seems some exapmles has no proposal rects??

It sometimes occurs because bugs are contained in codes of facial rectangles.

I used rectangle structure of OpenCV (x, y, w, h). However the image shapes of OpenCV are [h, w, c].
I think I made a mistake about width, height and image sizes.
The same can be said to #3.

The simplest solutions are to remove the cache and recompute it or to restart the training.
I would be glad if you give me a pull request about the bug.

@takiyu Hello，your code helps me a lot，Thanks for your contribution！But while I am running the code，it always tells me IndexError。After dection，I think there is no values in ssrects。I found that the filepath in aflw.sqlite doesn't correspond to the path in flickr/ file，does it influence my running？I hope you can give me some hints，Thank you very much。
