title: Summaries within Tensorflow Estimator API - More clarity needed
body: <p>Could someone help me on  creating tensor board summaries for loss, accuracy using Estimator API. I created <code>tf.summary.scalar('loss',loss)</code> and <code>tf.summary.scalar('accuracy',accuracy)</code> in my model_func. However, I am seeing only the <code>global_step</code> summary in my tensor board. Could some body point me to a relevant example that explains summary writer and logging hooks well using estimator API</p>
