Outputs a Summary protocol buffer with a histogram.

Migrate to TF2

This API is not compatible with eager execution and tf.function. To migrate to TF2, please use tf.summary.histogram instead. Please check Migrating tf.summary usage to TF 2.0 for concrete steps for migration.

How to Map Arguments

TF1 Arg Name TF2 Arg Name Note
name name -
values data -
- step Explicit int64-castable monotonic step value. If omitted, this defaults to tf.summary.experimental.get_step()
- buckets Optional positive int specifying the histogram bucket number.
collections Not Supported -
family Removed Please use tf.name_scope instead to manage summary name prefix.
- description Optional long-form str description for the summary. Markdown is supported. Defaults to empty.


Adding a histogram summary makes it possible to visualize your data's distribution in TensorBoard. You can see a detailed explanation of the TensorBoard histogram dashboard here.

The generated Summary has one summary value containing a histogram for values.

This op reports an InvalidArgument error if any value is not finite.

name A name for the generated node. Will also serve as a series name in TensorBoard.
values A real numeric Tensor. Any shape. Values to use to build the histogram.
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.

A scalar Tensor of type string. The serialized Summary protocol buffer.
