modifying install.sh for only cpu #14

Open cangozpi opened 2 years ago

cangozpi commented 2 years ago

Hi, I am using a laptop with only cpu available. I believe I have to modify the *.sh files as was specified in the repository's README. Problem is that I don't know how to modify it, and the way to do it was not specified. I would really appreaciate your help to get this FlowNet implementation to work on my cpu only device. Thanks a lot for your time.

Error upon running install.sh:

I think you have to use GPU for it since some operations are GPU-specific.
