how to correct this

i am using tensorflow version 0.8 and in linux

This seems like you have trainable variables without gradients. Can you
show your variables (print tf.all_variables) and probably gradients in
optimize_loss? Also you should try updating to 0.9 - there has been a lot
of issues addressed there.

There has been a lot of bug fixes since 0.8. Please try latest version. Please submit an issue to TensorFlow repo in the future instead.
