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. On Sat, Jul 2, 2016 at 1:23 PM vinayakumarr notifications@github.com wrote:

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.
