Most of the progress made in software projects comes from incrementalism. The ability to quickly see the outcome of an execution and iterate has been one of the main reasons for the success of Jupyter, especially in scientific exploratory workflows.

Jupyter users like to experiment in the notebook, and to use the notebook as an interactive communication tool.

However, for more classical software development tasks such as the refactoring of a large codebase, they often switch to general-purpose IDEs. The Jupyter project has made strides in the past few years towards filling that gap, notably with the JupyterLab project, which enables a richer UI including a file browser, text editors, consoles, notebooks, and a rich layout system.

However, a missing piece which has remained one of the main reasons for users to switch to a different tool is a visual debugger. This feature has long been requested by users, especially those accustomed to general-purpose development environments. Today, after several months of development, we are glad to announce the first public release of the Jupyter visual debugger! This is just the first release, but we can already set breakpoints in notebook cells and source files, inspect variables, navigate the call stack and more.

You can also try the debugger online with binder. Just click on the binder link:. The debugger front-end will be included in JupyterLab by default in a future release.

Once xeus-python and the debugger extension are installed, you should be all set to use the Jupyter visual debugger! Note: Depending on the platform, PyPI wheels are available for xeus-python, but they are still experimental.

Top 5 Best Jupyter Notebook Extensions

Jupyter kernels the part of the infrastructure that executes the user's code communicate with the rest of the infrastructure with a well-specified inter-process communication protocol.

Several communication channels exist, such as. The Control channel is similar to Shell but operates on a separate socket so that messages are not queued behind execution requestsand have a higher priority. Control was already used for Interrupt and Shutdown requests, and we decided to use the same channel for the commands sent to the debugger.

Two message types were added to the protocol:. A key principle to the Jupyter design is the agnosticism to the programming language. It is important for the Jupyter debug protocol to be adaptable to other kernel implementations. However, it was not quite sufficient in the case of Jupyter.First, the Python pip package needs to be installed.

Then, the notebook extensions themselves need to be copied to the Jupyter data directory. All of the nbextensions in this repo are provided as parts of a python package, which is installable in the usual manner, using pip or the setup. To install the current version from PyPi, simply type. All the usual pip options apply, e. You can install both using. This also automatically installs the Javascript and CSS files using jupyter contrib nbextension install --sys-prefixso the second installation step below can therefore be skipped.

You can also install from a cloned repo, which can be useful for development. You can clone the repo using. A jupyter subcommand is provided for the purpose:. The command does two things: installs nbextension files, and edits nbconvert config files. The first part is essentially a wrapper around the notebook-provided jupyter nbextension installand copies relevant javascript and css files to the appropriate jupyter data directory.

The command can take most of the same options as the jupyter-provided versions, including. In addition, two further option flags are provided to perform either only the config-editing operations, or only the file-copy operations:. Finally, the --perform-running-check option flag is provided in order to prevent the installation from proceeding if a notebook server appears to be currently running by default, the install will still be performed, even if a notebook server appears to be running.

An analogous uninstall command is also provided, to remove all of the nbextension files from the jupyter directories.

It makes the notebook aware of your conda environments, and it is required for Notebook Anaconda Cloud and Notebook Conda.Data says there are more than three million Jupyter Notebooks available publicly on Github.

There is roughly a similar number of private ones too. Even without this data, we are quite aware of the popularity of the notebooks in the Data Science domain. The possibility of writing codes, inspecting the results, getting rich outputs are some of the features that really made Jupyter Notebooks very popular.

But as it is said that all good things must come to an end, so will our favourite Notebook too. JupyterLab will eventually replace the classic Jupyter Notebook but for good. Some time back I published a guide on using Classic Jupyter Notebooks effectively. But as will be seen, JupyterLab is the next-generation user interface for Project Jupyter offering all the familiar building blocks of the classic Jupyter Notebook notebook, terminal, text editor, file browser, rich outputs, etc.

The basic idea of the Jupyter Lab is to bring all the building blocks that are in the classic notebook, plus some new stuff, under one roof. In case you are completely unfamiliar with Jupyter Lab, you can start reading the article right from Installation. But if you have already worked with them and want an advanced overview, skip the first four parts and jump straight to part 5 making sure that you are using the latest release.

JupyterLab can be installed using conda, pip or pipenv. Have a look at the official installation documentation for more details.

You can start the Jupyter by simply typing the following at the console:. JupyterLab will open automatically in the browser with an interface resembling the one below. This means everything is in place and you are good to go. The Menu Bar has the top-level menus that showcase the various actions that are available in Jupyter Lab. This consists of the commonly-used tabs. The left sidebar can be collapsed or expanded by selecting Show Left Sidebar in the View menu or by clicking on the active sidebar tab.

You can view the running session from the Running palette while the Commands palette lets you search for all the commands that are available. This is the area where the actual activity takes place.

It comprises of the notebooks, documents, consoles, terminals etc. Just double click or drag a file on to this area to start working. Workspaces can be saved on the server with named workspace URLs.

Also, you can switch between the classic Notebook view and the JupyterLab view by changing the lab to tree in the url of the Jupyter Lab. In this section, we will quickly see how to work with files in Jupyter Lab. This opens a new Launcher tab in the main work area could enabling us to create a Notebook, Console, terminal or text editor. The same action can also be achieved by using the File tab.

Once opened, the files can be renamed and even downloaded. Opening files is a very straightforward process.

Either double click on them or access them through the upper File Tab. These were just the basics of Jupyter Labessentially to get started. Another reason is that all these components work as standalone features and not integrated.

Jupyter Lab tends to plug this pain area by integrating all the features into a single interactive and collaborative environment. The notebook document format used in JupyterLab is the same as in the classic Jupyter Notebook.I plan on using Split. Do I…. I think I traced it down to the layout in Phosphor. Are you set on using split. Likely using the phosphor split view will be easiest, and most consistent with other split views in JupyterLab. If you want to use split.

So far so good. I also tried directly setting the content like nbTracker. The biggest problem I see is that you are inserting a widget in the widget hierarchy, so code that depends on the notebook panel.

For example, remove the widget by setting its. Perhaps the best thing to do here that does not break the notebook panel widget interface is create a new notebook viewer that makes the top-level widget a split panel. You can reuse the existing notebook component, of course. Any guidance for how to approach this would be much appreciated. I get the error of duplicate registered factories, and the default notebook factory still opens notebooks instead of my new factory.

Seeking suggestions for the best way to implement a split-view JupyterLab notebook extension JupyterLab.
