Args:
name: A name for the generated node. If display_name is not set, it will
also serve as the tag name in TensorBoard. (In that case, the tag
name will inherit tf name scopes.)
tensor: A tensor of any type and shape to serialize.
summary_description: A long description of the summary sequence. Markdown
is supported.
collections: Optional list of graph collections keys. The new summary op is
added to these collections. Defaults to `[GraphKeys.SUMMARIES]`.
summary_metadata: Optional SummaryMetadata proto (which describes which
plugins may use the summary value).
family: Optional; if provided, used as the prefix of the summary tag,
which controls the name used for display on TensorBoard when
display_name is not set.
display_name: A string used to name this data in TensorBoard. If this is
not set, then the node name will be used instead.
Returns:
A scalar `Tensor` of type `string`. The serialized `Summary` protocol
buffer.
