After following all the steps and running this line !python eval.py --img1=./images/first.png --img2=./images/second.png --flow=./out.flow --display_flow=True

I got this error:

Same here. What I found is that the sess returns an array of NaNs flow = sess.run(out, feed_dict={tens1: inp1, tens2: inp2})[0, :h, :w, :]

But the problem only occurs in the part where you'd use it the first time, which happens to be col0 = tmp[k0] / 255.0 as k0 and k1 should get their values from there
