  5. Why I encounter error 502 when I try to log in?

    Hey, does anyone knows if the workbench is undergoing any maintenance or something else? I used the Jupyter Notebooks just a few hours ago and it was good. But just now, I can't log into the workbench, there's always a 502 error. Is this a temporary issue or other things are happening?
    Thanks.

  12. Autocomplete commands in R using tab

    In Python notebooks, you can use tab to autocomplete a command. Would like the same feature in R.

  13. Jupyter Notebook doesn't work again

    Hi,
    When I open Jupyter Notebook from a Coursera course, I got 500 Internal Server Error.
    It happens often and this is one of the most important parts of many courses.
    Therefore I have three questions:
    1) Is it possible to get a refund based on the fact that we pay for sth we cannot use?
    2) When the issue will be resolved?
    3) What availability can we expect (how many days a month it is expected to be working)

  16. mxnet with gpu

    The Idea is to installing mxnet-cu80 (mxnet-cu90, mxnet-cu91 or mxnet-cu92). But the issue is mxnet-80 has dependence with the instalation of libnvrtc8.0 which is installed by the linux console. And there is not possible due to Administrative privileges.

    Thank You!

  20. 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.
