  1. 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.

  4. 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.

  16. 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
