-  Args:
-    db_uri: For example "file:/tmp/foo.sqlite".
-    experiment_name: Defaults to YYYY-MM-DD in local time if None.
-      Empty string means the Run will not be associated with an
-      Experiment. Can't contain ASCII control characters or <>. Case
-      sensitive.
-    run_name: Defaults to HH:MM:SS in local time if None. Empty string
-      means a Tag will not be associated with any Run. Can't contain
-      ASCII control characters or <>. Case sensitive.
-    user_name: Defaults to system username if None. Empty means the
-      Experiment will not be associated with a User. Must be valid as
-      both a DNS label and Linux username.
-    name: Shared name for this SummaryWriter resource stored to default
-      `tf.Graph`.
