  4. 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.

  5. 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.

  7. Import Torchvision libraries cause error

    Despite Torchvision librairy is correctly installed (conda list show the package as 0.2.1 version), the import (ie "import torchvision.transforms as transforms") cause an error ("cannot import name 'PILLOW_VERSION'"). Tried to install a newer version of Torchvision (0.4.2) but cause another error.

  15. 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

  18. 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

    In the attached screenshot, please observe that all my worksbooks that I worked on for my deep learning class are missing. Please fix asap.
