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. That is especially true if you want to go beyond watching your learning curve and want to see additional information like performance charts, or prediction visualizations after every epoch.In machine learning, to improve something you often need to be able to measure it. Monitoring ML experiments with dedicated tools gives you the comfort of knowing what is going on with your training runs. Especially if you don’t have access to the machine (computational cluster at University, VPN at work, Cloud server you’re using somewhere, or when you’re on a bus :)). Sometimes you can’t even access the model training environment.Īnd that’s where tools come in handy! You can use them to flexibly monitor your ML experiments and look at model training information whenever you need to. When you look at logs you don’t see the change over time immediately (think learning curve vs losses on epoch 10), You cannot look at your console logs all the time, Monitoring machine learning experiment runs is an important and healthy practice but it can be a challenge. There are a ton of JupyterLab extensions that you may want to use.Įxtension Manager (little puzzle icon in the command palette) lets you install and disable extensions directly from JupyterLab. If you would like to see how to create your own extension read this guide. Technically JupyterLab extension is a JavaScript package that can add all sorts of interactive features to the JupyterLab interface. JupyterLab extension is simply a plug-and-play add-on that makes more of the things you need possible. “JupyterLab is designed as an extensible environment”. In this article, we’ll talk about JupyterLab extensions that can make your machine learning workflows better. One of the great things about Jupyter ecosystem is that if there is something you are missing, there is either an open-source extension for that or you can create it yourself. JupyterLab, a flagship project from Jupyter, is one of the most popular and impactful open-source projects in Data Science.
