tf.summary.text

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

Writes text Tensor values for later visualization and analysis in TensorBoard.
Writes go to the current default summary writer.  Like <a href="../../tf/summary/scalar"><code>tf.summary.scalar</code></a>
points, text points are each associated with a `step` and a `name`.
All the points with the same `name` constitute a time series of text values.

For Example:

```python
test_summary_writer = tf.summary.create_file_writer('test/logdir')
with test_summary_writer.as_default():
    tf.summary.text('first_text', 'hello world!', step=0)
    tf.summary.text('first_text', 'nice to meet you!', step=1)
```

The text summary can also contain Markdown, and TensorBoard will render the text
as such.

```python
with test_summary_writer.as_default():
    text_data = '''
          | *hello* | *there* |
          |---------|---------|
          | this    | is      |
          | a       | table   |
    '''
    text_data = '

Since text is Tensor valued, each text point may be a Tensor of string values.
rank-1 and rank-2 Tensors are rendered as tables in TensorBoard.  For higher ranked
Tensors, you'll see just a 2D slice of the data.  To avoid this, reshape the Tensor
to at most rank-2 prior to passing it to this function.

["Displaying text data in TensorBoard"](https://www.tensorflow.org/tensorboard/text_summaries).

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 UTF-8 string Tensor value.
  step: Explicit `int64`-castable monotonic step value for this summary. If
    omitted, this defaults to <a href="../../tf/summary/experimental/get_step"><code>tf.summary.experimental.get_step()</code></a>, 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 emitted because no default
  summary writer was available.

Raises:
  ValueError: if a default writer exists, but no step was provided and
    <a href="../../tf/summary/experimental/get_step"><code>tf.summary.experimental.get_step()</code></a> is None.
