the tensorboard summary is slow

[liyuanhangsc]

in my gpu server, remove the summary tensor make training 10x times faster. Please consider add a switch to close tensorboard summary.

I'm pretty sure the culprit is

char-rnn-tensorflow/model.py

Lines 85 to 86 in 401ebfd

	tf.summary.histogram('logits', self.logits)
	tf.summary.histogram('loss', loss)

(Histogram summaries involve transferring a lot of data from the GPU to the CPU.)

You might try commenting them out. The graph and train_loss summaries are usually more useful, anyways.

How can I see the accuracy rate in tensorboard?
