  3. A clever idea...get Jupyterlab to work!

    Just make the basic tool work when you click on it. For three days in a row I get "Application Not Responding"

  5. Give students the code in .ipynb files to store locally rather than hosting them in a faulty cloud service

    IF


    1. This service is being paid for

    2. Your Jupyter Notebooks service is often down

    3. The course is paid for on a monthly basis (Time = Money)

    THEN

    You should provide the .ipynb files for student to store on their own device to complete lab sessions

    ELSE

    Respond to user queries/ Get it fixed quick

    AND

    Refund everyone for the time the service is down/intermittent.

    OR

    Provide the service at no cost.

  8. 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

  17. 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.

  18. 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?
