    name, tensor, collections=None, family=None
)

The generated Summary has a Tensor.proto containing the input Tensor.

Args
name	A name for the generated node. Will also serve as the series name in TensorBoard.
tensor	A real numeric Tensor containing a single value.
collections	Optional list of graph collections keys. The new summary op is added to these collections. Defaults to [GraphKeys.SUMMARIES].
family	Optional; if provided, used as the prefix of the summary tag name, which controls the tab name used for display on Tensorboard.

Returns
A scalar Tensor of type string. Which contains a Summary protobuf.

Raises
