can confirm currently MXNet doesn't support both update global running mean/var and use running mean/var to calculate grads in one pass of Batchnorm, while Keras-MXNet can support it by passing mean/var as arguments to Batchnorm as a workaround adding the support would still have constraints, especially cudnn doesn't support it so it cannot run with the best performance; some other frameworks like caffe doesn't support this either it can be implemented by modifying batch_norm.cc/cu and add "use_shift_scale" option to control it ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
