UnboundLocalError: local variable 'outs' referenced before assignment

[thassan66]

I am trying to evaluate the images via 'inception.015-0.27.hdf5' model.
I set test_data_num = 15 in order to check its working or not. i am getting following error.
before that i tried on while dataset and its running since 2017-12-09 10:01:09 and the process is not completed. i am getting upset if after so many days i will get an exception so that i tried with small amount of images but it gaves error.
Please help to get rid of this.
