Outputs a Summary protocol buffer containing a single scalar value.

tf.compat.v1.summary.scalar(
    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:

• ValueError: If tensor has the wrong shape or type.
