Hi,
I think the last fc layer may should not use an activation unit.
If the output of fc layer is all negative, after the ReLU unit, it would be all zero.
In this case, top_k_op = tf.nn.in_top_k(fc_out, label_holder, 1) will always return True.

I think you are right.
When I use this code to train , the result will be all the same sometimes.
You can just remove parameter of activation.
