Jupyter Notebooks

  1. Databases and SQL for Data Science - Week 5 - I cannot proceed with the exercises - AttributeError

    18-04-2021
    (for several days JupyterLab on skills network labs has serious connection problems)

    I was using this db quietly until a few days ago, I thought of a syntax error but everything seems ok to me. I am correctly connected to the DB but I cannot proceed with the exercises because I get this error message

    'DB2ExecutionContextibmdb' object has no attribute 'compiled_parameters'

    please, can you help me?

  8. Update conda please.

    When I install packages, I receive the following note:

    ==> WARNING: A newer version of conda exists. <==

    current version: 4.8.3

    latest version: 4.8.4

    Please update conda by running

    $ conda update -n base -c defaults conda

    Without the update, invoking the .head() method causes an error

    AttributeError: 'NoneType' object has no attribute 'items'

    However, print(df.head()) does output a header.

  9. unable to open notebook as saying i am trying to close an unsaved notbook

    i am doing a Python for Data Science course on edX and cannot open one of the notebooks as I keep getting "File "PY0101EN-1.3notebookquizzStringOperations.ipynb" has unsaved changes, close without saving?"

    no matter if I press OK or Cancel, i still cannot open it and continue with my study. I have tried clearing cache and rebooting the machine. Tried closing unsaved and re-opening, still says i have an unsaved notebook that i am trying to close. Stuck here, any ideas?

  18. ' HTTP Error 403: Forbidden'

    I keep on getting ' HTTP Error 403: Forbidden' every time i try to import a csv file into JupyterLab. This only occurred recently, I've had no problems before. This is true for chrome and explorer.

  20. Missing all Lab Files

    I am not able to find files (Jupyter Notebooks) under lab section on Jupyter Lab.

    It says:
    Cannot openCould not find path: /labs/DV0101EN/DV0101EN-1-1-1-Introduction-to-Matplotlib-and-Line-Plots-py-v2.0.ipynb

    Also all the previous files are missing from labs directory.
    How can I practice, if I do not get the jupyter files with exercises in it. There were other directories too, from other courses.
    Please restore everything for me.
