Jupyter Notebooks

  1. 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

  8. Cannot open Jupyter for IBM PowerAI getting error 502 Bad Gateway

    I am getting error 502 Bad Gateway since yesterday while connecting to Jupyter for IBM PowerAI.

    Is there some kind of maintenance or issue going on?

    Because if it is permanent or if it will take a lot of time I would atleast like to retrieve some of the files that I was working on so that I can resume elsewhere

  10. 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.

  11. 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. 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.

  13. Notebooks do not load

    When loading a notebook (even an empty one), I see the loading icon spin for many minutes then receive the error: "Notebook Load Failed: We were not able to load the notebook you requested. Click here to try again."

    Is there an issue with my account profile?

  14. 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?

  19. 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!
