tf.compat.v1.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.

Eager Compatibility

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