When training with methods such as tf.GradientTape(), use tf.summary to log the required information. You can see what other dashboards are available in TensorBoard by clicking on the "inactive" dropdown towards the top right. For example, the Keras TensorBoard callback lets you log images and embeddings as well. Distributions can be found in the Distributions dashboard.Īdditional TensorBoard dashboards are automatically enabled when you log other types of data. Histograms can be found in the Time Series or Histograms dashboards. This can be useful to visualize weights and biases and verify that they are changing in an expected way. Histograms and Distributions show the distribution of a Tensor over time.Graphs can be found in the Graphs dashboard. In this case, the Keras graph of layers is shown which can help you ensure it is built correctly. Scalars can be found in the Time Series or Scalars dashboards. You can use them to also track training speed, learning rate, and other scalar values. Scalars show how the loss and metrics change with every epoch.%tensorboard -logdir logs/fitĪ brief overview of the visualizations created in this example and the dashboards (tabs in top navigation bar) where they can be found: On the command line, run the same command without "%". In notebooks, use the %tensorboard line magic. ![]() The two interfaces are generally the same. Start TensorBoard through the command line or within a notebook experience. Tensorboard_callback = tf.(log_dir=log_dir, histogram_freq=1) Place the logs in a timestamped subdirectory to allow easy selection of different training runs. Additionally, enable histogram computation every epoch with histogram_freq=1 (this is off by default) When training with Keras's Model.fit(), adding the tf. callback ensures that logs are created and stored. (x_train, y_train),(x_test, y_test) = mnist.load_data() Using the MNIST dataset as the example, normalize the data and write a function that creates a simple Keras model for classifying the images into 10 classes. ![]() # Clear any logs from previous runs rm -rf. # Load the TensorBoard notebook extension The remaining guides in this website provide more details on specific capabilities, many of which are not included here. This quickstart will show how to quickly get started with TensorBoard. It enables tracking experiment metrics like loss and accuracy, visualizing the model graph, projecting embeddings to a lower dimensional space, and much more. TensorBoard is a tool for providing the measurements and visualizations needed during the machine learning workflow. In machine learning, to improve something you often need to be able to measure it.
