When I open Windows Explorer through Ubuntu it goes to a different folder than in the guide

Please make sure:

  • you are running the command explorer.exe . including the dot at the end.
  • you are running Windows 10 version 1909 or newer.

Ubuntu on Windows 10 high CPU usage crashes

  • First please make sure you are running Windows 10 version 1909 or newer.
  • Then, try following these steps

When I pull from the batch6-students repository I get the error

error: Your local changes to the following files would be overwritten by merge:
<some files>
Please commit your changes or stash them before you merge.
Aborting

git is telling us that changes were made by you to the files on the ~/projects/batch6-students folder, and is not pulling the changes made by the instructors because they would override the changes that you made there. To fix this do the following:

  1. make sure that any change you made to the files on ~/projects/batch6-students (that you want to not lose) is saved in your ~/projects/batch6-workspace repository (see https://github.com/LDSSA/batch6-students#updates-to-learning-units for how to do this), and if you don't want to keep the changes you made to these files, just continue on to the next step

  2. go to the ~/projects/batch6-students folder and run:

    cd ~/projects/batch6-students
git stash

  3. now you can pull from the batch6-students repository:

    git pull

When I try to open jupyter notebook I get the error

migs-MBP% jupyter notebook
zsh: command not found: jupyter

Before opening jupyter notebook activate your virtual environment:

source ~/.virtualenvs/slu00/bin/activate

When I use the cp command the > sign appears and the command does not execute

cp -r ~/projects/batch6-students/"S01 - Bootcamp and Binary Classification"/"SLU01 - Pandas 101" ~/projects/batch6-workspace/"S01 - Bootcamp and Binary Classification"
>

Make sure to use this type of quotes " and not these ones “.

When setting up Python 3.x I get an error

When I run this command:

sudo add-apt-repository ppa:deadsnakes/ppa

I get this error:

W: GPG error: http://apt.postgresql.org/pub/repos/apt focal-pgdg InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7FCC7D46ACCC4CF8

Solution: Take the id in front of NO_PUBKEY (in my case its 7FCC7D46ACCC4CF8) and run the following command:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7FCC7D46ACCC4CF8

Nothing happens when I type my password

In step two it asks me for the computer password. However, I am not being able to write anything

Solution: When you write your password you might not get any visual feedback and that's okay! Write it as normal and hit enter when you're done!

I still have a NotImplemented error

I've completed the exercise in the Exercise Notebook but when I run the cell I get a NotImplementedError.

Solution: The raise NotImplementedError() are added to the exercise cell as a placeholder for where you're supposed to add your solution/code. It is meant to be removed!

I get an error when creating the virtual environment

I ran python3.8 -m venv ~/.virtualenvs/slu00, but got the following error:

The virtual environment was not created successfully because ensurepip is not available.

This can happen if either you skipped the installation of python-pip, or the version of the python you're calling doesn't have python pip installed.

As we're using python3.8 for this academy, and if you've followed all the steps in this README correctly, you should be able to create the virtual environment with:

python3.8 -m venv ~/.virtualenvs/slu00

Checksum verification failed

I'm getting "checksum verification failed" on a portal submission.

Some metadata can change when you open your jupyter notebook using vscode. Try running the notebooks from start to end in Jupyter and resubmit.

My problem is not listed here what should I do?
