TensorBoard

Description

Enable visualizations for TensorBoard.

Usage

TensorBoard(
  log_dir = "logs",
  histogram_freq = 0,
  write_graph = TRUE,
  write_images = FALSE,
  update_freq = "epoch",
  profile_batch = 2,
  embeddings_freq = 0,
  embeddings_metadata = NULL
)

Arguments

log_dir

the path of the directory where to save the log files to be parsed by TensorBoard.

histogram_freq

frequency (in epochs) at which to compute activation and weight histograms for the layers of the model. If set to 0, histograms won't be computed. Validation data (or split) must be specified for histogram visualizations.

write_graph

whether to visualize the graph in TensorBoard. The log file can become quite large when write_graph is set to TRUE.

write_images

whether to write model weights to visualize as image in TensorBoard.

update_freq

''batch'‘ or '’epoch'‘ or integer. When using '’batch'', writes the losses and metrics to TensorBoard after each batch. The same applies for ''epoch'‘. If using an integer, let’s say '1000', the callback will write the metrics and losses to TensorBoard every 1000 samples. Note that writing too frequently to TensorBoard can slow down your training.

profile_batch

Profile the batch to sample compute characteristics. By default, it will profile the second batch. Set profile_batch=0 to disable profiling. Must run in TensorFlow eager mode.

embeddings_freq

frequency (in epochs) at which embedding layers will be visualized. If set to 0, embeddings won't be visualized.

embeddings_metadata

a dictionary which maps layer name to a file name in which metadata for this embedding layer is saved. See the [details]( https://www.tensorflow.org/how_tos/embedding_viz/#metadata_optional) about metadata files format. In case if the same metadata file is used for all embedding layers, string can be passed.

Details

TensorBoard is a visualization tool provided with TensorFlow. This callback logs events for TensorBoard, including: * Metrics summary plots * Training graph visualization * Activation histograms * Sampled profiling If you have installed TensorFlow with pip, you should be able to launch TensorBoard from the command line: “'sh tensorboard –logdir=path_to_your_logs “' You can find more information about TensorBoard [here](https://www.tensorflow.org/get_started/summaries_and_tensorboard).

Value

None

Raises

ValueError: If histogram_freq is set and no validation data is provided.
