how to print accurate in this code?

[YuZheng23]

Thank you very much for the excellent work you do
I successfully ran your code, but I noticed that the output contains these three data:
training/train_loss_mean
training/train_loss_std
training/action_error
but not the accuracy data, what should I do if I want to print the accuracy of this code?
