UPDATE 02/03/2018 Now this option is already built in in the settings menu! Recently this issue was closed on the GitHub, and finally it is possible to edit settings of the jupyter lab. Hurray! The procedure is described in this pull request. Just update your jupyter-lab (now it is version 0.27.0) and go to File … Read more
If you click the “Tabs” menu in Jupyter Lab, the keyboard shortcut should be listed there. example: On my macbook it is CTRL+SHIFT+[ or CTRL+SHIFT+]
A couple things might be happening. For some reason is your Notebook “Not Trusted?” This will stop the Plotly javascript from rendering anything below. Another possibility is that you don’t have the Plotly extension installed for Jupyter Lab. In Lab, as compared to Notebooks, there are a lot more restrictions on what javascript can execute, … Read more
Its the space. Its always the space. Never ever use spaces within package name. Its always either namepart1-namepart2 or namepart1namepart2. This is because arguments are separated by space. So if you put space in between, it makes pip think that you want to install two different packages named jupyter and lab. Just use: python -m … Read more
The simplest workaround to this seems to be the built-in cell magic %%capture: %%capture output # Time-consuming code here Save, close tab, come back later. The output is now stored in the output variable: output.show() This will show all interim print results as well as the plain or rich output cell.
conda update jupyter will not automatically update jupyterlab. You have to explicitly request an update of jupyterlab: conda update jupyterlab
JupyterLab 3.0+ Install jupyterlab and ipympl. For pip users: pip install –upgrade jupyterlab ipympl For conda users: conda update -c conda-forge jupyterlab ipympl Restart JupyterLab. Decorate the cell containing plotting code with the header: %matplotlib widget # plotting code goes here JupyterLab 2.0 Install nodejs, e.g. conda install -c conda-forge nodejs. Install ipympl, e.g. conda … Read more
JupyterLab now prefers a model where arbitrary javascript is no longer allowed to be embedded in a cell’s output, which is how many interactive Jupyter Notebook modules used to work. They now ask that modules with interactivity create a JupyterLab extension. ipywidgets provides @jupyter-widgets/jupyterlab-manager extension which satisfies this requirement. When using ipywidgets 7.6 or newer … Read more
adding to previous answers, to get the notebook name run the following in a cell: %%javascript IPython.notebook.kernel.execute(‘nb_name = “‘ + IPython.notebook.notebook_name + ‘”‘) this gets you the file name in nb_name then to get the full path you may use the following in a separate cell: import os nb_full_path = os.path.join(os.getcwd(), nb_name)
Jupyter Lab does support interactive matplotlib through the jupyter-matplotlib extension. The installation procedure is slightly more involved, but works fine. Since the ipympl Jupyter Lab version requires NodeJS, and NodeJS requires Windows 8.1, ipympl also has this requirement. As before, it is important to invoke the iPython magic command before plotting: Usage: %matplotlib widget Installation: … Read more
