hello~
when I'm running 06-modern-convnet with tensorflow 1.4, it presents an error. Could you please tell me how to solve it? My friends also have this prolbem.

I have read the source code of tf.train.ExponentialMovingAverage
there should have a line of code:
ema.apply([batch_mean, batch_var])
before calculating batch_mean and batch_var
and that works for me
