Outputs a Summary protocol buffer containing a single scalar value.
tf.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.
