Writes a summary using raw tf.compat.v1.Summary protocol buffers.

    tensor, step=None, name=None

Experimental: this exists to support the usage of V1-style manual summary writing (via the construction of a tf.compat.v1.Summary protocol buffer) with the V2 summary writing API.


  • tensor: the string Tensor holding one or more serialized Summary protobufs
  • step: Explicit int64-castable monotonic step value for this summary. If omitted, this defaults to tf.summary.experimental.get_step(), which must not be None.
  • name: Optional string name for this op.


True on success, or false if no summary was written because no default summary writer was available.
