Merges all summaries collected in the default graph.

    key=tf.GraphKeys.SUMMARIES, scope=None, name=None


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


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.


  • RuntimeError: If called with eager execution enabled.

Eager Compatibility

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