  2. 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.

  3. Sidebar for the management and uploads should be on the left side

    It is a bit strange to see the side bar on the right. Common convention is to have it on the left of the notebook.

  4. Once I open "See all notebooks" or "See all data", I can never close the tab again

    In the sidebar, if I click on "See all notebooks" or "See all data", it opens a new tab called "Search - type notebook".

    Once this is opened, there is no way to close it.

  6. Actively running notebook sometimes get oddly moved to "Recent Data"

    Happens in Python (not sure about R), but sometimes when I am running a cell, as it is processing, the notebook in the sidebar "jumps" from "Recent Notebooks" to "Recent Data". The kernel remains active.

    I will try to post a sample script that is reproducible, but right now this issue appears very inconsistently.

  7. Registration page is shown after a user just registered

    This is a small usability issue. After clicking on the link within the confirmation email, and setting a password for the first time, the user is finally registered. The page however will redirect him or her to /register after having just completed their registration. The desired outcome would be a redirect to the homepage (if the user session is kept) or to the login page (if it's not).

  8. OAuth2 server asks for empty permissions

    I ran into this small usability issue. When I logged in with my user (cangiano) the OAuth2 server asked me to approve special permissions, only to fail to show me the list of required permissions. Clicking "Allow" lets you through, but it might be confusing for some users. Furthermore the "Save Consent" option doesn't appear to actually save the consent at the next login.

    See https://www.evernote.com/l/AAG97TbetTNMSImxEpixDDCN5X0QvxhySbI for reference.

  10. Insert Import for Python file not working

    The functionality to have a context menu for Notebooks and Python files is quite nice, but unfortunately it does not work for me.

    I have a larger project with many local *.py files that are imported, yet in my Jupyter notebooks the dot-string that the "Insert Import" functionality gives me does not resolve. I.e. I get errors like:

    ----> 3 import data.mycode.QFog.Dag

    ImportError: No module named 'data'

    I am suprised that this issue is not reported yet. It makes working with a large python project virtually impossible on the platform.

  11. Jupyter notebook doesn't connect to the kernel

    Jupyter notebook when opened in labs for TEnsorflow training, the kernel is not connected and keeps retrying to connect to the kernel.
    I think the kernel is an IBM system and it is blocked from the websense of my organization network.
    Can you please provide the URL for the kernel so that I can raise a request to my IT team to bypass the URL/domain(s) so as to connect to the kernel successfully.
    Please supply the complete url containing the domain and subdomains, specifically.
    Thanks.

  17. What's the idle policy/idle timeout for jupyter lab?

    Sometimes we have to have long-running tasks! How does idling work for jupyter lab? Can I close the browser tab or suspend my local client while the kernel continues running on your side?

    If I connect from two different computers, do I use two different kernels, or can I continue from the same kernel?

  20. Install Ta-lib

    I follow the knowledge base suggestion to install Ta-lib: !conda install -c quantopian ta-lib --yes

    However, I encountered the following error messages.

    Solving environment: failed

    UnsatisfiableError: The following specifications were found to be in conflict:
    - scikit-learn==0.20.1
    - ta-lib
    - tensorflow==1.8.0
    Use "conda info <package>" to see the dependencies for each package.

    Can you tell me how to solve this problem?

    Thank you
