[cloud-tensorflow-mnist]: Section 8 using tf.nn.softmax_cross_entropy_with_logits

[hgarrereyn]

For part 4/4 of section 8, the tutorial says to use:

cross_entropy = tf.nn.softmax_cross_entropy_with_logits(Ylogits, Y_)

However, when you use this function you must use named arguments (or it will not run):

cross_entropy = tf.nn.softmax_cross_entropy_with_logits(logits=Y, labels=Y_)

It's a technicality (and the error message you get is straightforward) but I think this might be a point of confusion for people as the line doesn't work out of the box.
