Can't run classifier.py

[Sivaramakrishnan Nageswaran]

Hi,

   I installed openface on my GPU machine (having Ubuntu 16.04) as mentioned in the following link : https://cmusatyalab.github.io/openface/setup/#installing-open-face-using-conda-osx-and-gnulinux). After installation, when I run the following command : ./demos/classifier.py infer models/openface/celeb-classifier.nn4.small2.v1.pkl ./images/examples/carell.jpg, am getting the following error.

(openface) user1@user1-GPU3:~/facereco/openface$ ./demos/classifier.py infer models/openface/celeb-classifier.nn4.small2.v1.pkl ./images/examples/carell.jpg

Kindly let me know how I should proceed further.
