tf.summary.scalar

Write a scalar summary.

tf.summary.scalar(
    name, data, step=None, description=None
)

Arguments
`name`	A name for this summary. The summary tag used for TensorBoard will be this name prefixed by any active name scopes.
`data`	A real numeric scalar value, convertible to a `float32` Tensor.
`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.
`description`	Optional long-form description for this summary, as a constant `str`. Markdown is supported. Defaults to empty.

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

Raises
`ValueError`	if a default writer exists, but no step was provided and `tf.summary.experimental.get_step()` is None.
