Inference on batch of images

Hi, thank you for your work!

I'm wondering if it's possible to inference this python module https://github.com/deepinsight/insightface/tree/master/python-package for a batch of images? In order to use it fast for several images. And also the question is if it is using gpu/cuda on inference and if it's not -- is it possible to use it's advantage to improve the inference in terms of speed?
