IndexError: only integers, slices (`:`)

Hello,

Your code looks awesome! I'm trying to get it running on my machine, and I'm bumping into this error: not sure what I'm doing wrong?

On a Linux Ubuntu 16.04 machine, ran the build.sh script, appear to have prerequisites installed. Running python compute_flow.py -kitti -pcaflow image1.png image2.png output.flo as shown:
