Streamlit.io is another new not-really-a-notebook alternative, pip installable and locally runnable. Take it for a spin today by heading over to our website or directly to the code and let us know what you think! Take a look at our currently open issues and to see what we’re planning, and, of course, PRs are always welcome! Streamlit.io The developers also seem to be engaging with the “open” thing… On the topic of charts, if you have a Vega chart spec, you can paste that into a Vega spec type code cell and it will render the chart when you run the cell: I couldn’t seem to click through to raise a more detailed error trace though? This did make me realise that cell lines are line numbered on one side and there’s a highlight shown on the other side which line errored. The IPython magic used in Jupyter notebooks throws an error, for example:
Jupyterlab variable inspector how to#
I couldn’t see how to render a matplotibl plot: There is a variable inspector, although rather than showing or previewing cell state, you just get a listing of variables and then need to click through to view the value: The execution model is supposed to enforce linear execution, but I could insert a cell after and unrun cell and get an error from it (so the execution model is not run all cells above either literally, or based on analysis of the programme abstract syntax tree?) I couldn’t see how to connect to a SQL database, nor did I seem to get an error from running a presumably badly formed SQL query? Running cells are indicated with a green sidebar to the cell (you can get a similar effect in Jupyter notebooks with the multi-outputs extension): Instead I have to enter import pandas as pd ESC RETURN. I can’t write import pandas as pd RETURN because that renders as import pandas as pandas. ipynb.Ĭode cells are sensitive to syntax, with a code completion prompt: One of the things I note is the filetype. The UI is clean, and whilst perhaps slightly more cluttered than vanilla Jupyter notebooks it’s easier on the eye (to my mind) than JupyterLab.Ĭells are code cells or text cells, the text cells offering a WYSIWYG editor view:
Jupyterlab variable inspector install#
Netflix have announced a new notebook candidate, Polynote, capable of running polyglot notebooks (scala, Python, SQL) with fixed cell ordering, variable inspector and WYSIWYG text authoring.Īt the moment you need to download and install it yourself (no official Docker container yet?) but from the currently incomplete installation docs, it looks like there may be other routes on the way… A handful of brief news-y items… Netflix Polynote Notebooks
