  10. Discussion on Jupyter Notebook labs

    I would like to open a discussion about the working materials in the Jupyter Notebook labs. About the quality, the positive or negative remarks. Also, about some parts that are a bit unexplained or can be done differently. In other words, my idea is to post some feedbacks about the Jupyter Notebook labs.

  12. 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"

  13. 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.

  15. /bin/sh: 1: conda: not found

    I'm getting below error:
    !conda -- version

    /bin/sh: 1: conda: not found

    Please provide exact fix steps as I'm a real newbie.

  16. 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
