gramce opened a new issue #9491: is_train in model.backward will change the bias parameter?
URL: https://github.com/apache/incubator-mxnet/issues/9491
 
 
   I ran the example adversary_generation.
   Print the parameter bias before and after the  model.backward([out_grad]) and find that the value changes.
   If run model.backward([out_grad], is_train=0), the value doesn't change any more.
   is_train in model.backward will change the bias parameter?
