tf.summary.merge_all(
    key=tf.GraphKeys.SUMMARIES, scope=None, name=None
)

Args
`key`	`GraphKey` used to collect the summaries. Defaults to `GraphKeys.SUMMARIES`.
`scope`	Optional scope used to filter the summary ops, using `re.match`

Returns
If no summaries were collected, returns None. Otherwise returns a scalar `Tensor` of type `string` containing the serialized `Summary` protocol buffer resulting from the merging.

Raises
`RuntimeError`	If called with eager execution enabled.

Not compatible with eager execution. To write TensorBoard summaries under eager execution, use tf.contrib.summary instead.
