Jupyter Notebooks

  1. Tutorial #6 Not loading

    I was able to open the first 5 tutorial notebooks without a problem by clicking import on the welcome page. However, for the 6th tutorial I cannot open it using the same step.

    I put in this command !ls to list all the files and I see it there. However, i cannot access it from the sidebar.

  6. Jupyter notebooks go missing mysteriously

    I have recently noticed that when I open the DS Workbench to go to Juypter, my notebooks are missing. It sometimes shows only 1 of workbooks, other times, it shows Untitles1.pnyb

    In the attached screenshot, please observe that all my worksbooks that I worked on for my deep learning class are missing. Please fix asap.

  7. Intellisense-like popup-help. That is. hover over a function, class, etc. and get a short description

    Most Python IDEs have some sort of pop-up help. e.g. hover over a function (built-in, library, user defined) and get a pop-up showing the signature.

    Also highlight (e.g. with red squiggles) errors in syntax. Highlight in blue squiggles using a variable before definition, etc.

  10. Ability to customize themes/colors for notebooks

    The coloring difference between Markdown and Code cells is a little too subtle. Would be great to be able to change themes (e.g.: dark theme for Code, light theme for Markdown).

  11. Recover deleted notebook and data

    There is no confirmation to delete notebooks/data, or the ability to recover delete notebooks/data. This is dangerous! :O

  17. need a way to manage running notebooks

    When I have many notebooks and some of them are running, the kernel does not get started. So, I have to go through all of my notebooks, find the ones that are running and stop them. I need a feature to show me all of the running notebooks in one screen, instead of checking each of them one by one.

    print("The dot product is", np.dot(a,b))
    -->

    This code is giving error.

  20. Share ipython notebooks on github

    If you could provide an option to share ipython notebooks in DSWB on github, that would be very helpful.

    Thanks!
