title: What is difference between tf.truncated_normal and tf.random_normal?
body: <p><code>tf.random_normal(shape, mean=0.0, stddev=1.0, dtype=tf.float32, seed=None, name=None)</code> outputs random values from a normal distribution.</p>
  
  <p><code>tf.truncated_normal(shape, mean=0.0, stddev=1.0, dtype=tf.float32, seed=None, name=None)</code> outputs random values from a truncated normal distribution.</p>
  
  <p>I tried googling 'truncated normal distribution'. But didn't understand much.</p>
