When I was training data, I changed the value of evaluate_every to 100, and the original value was 500. However, there are the following errors. Can you help me solve this problem again? Thank you very much for your help.

UnboundLocalError: local variable 'indices' referenced before assignment
This problem can be solved by adding a new code “** global indices**” in front of the code of the “indices = rng.randint(0,self.n_examples,size=(N,))” sentence.
