Setup instructions

You will find below the instructions to set up you computer for Le Wagon Data Science course

Please read them carefully and execute all commands in the following order. If you get stuck, don't hesitate to ask a teacher for help 🙋

Let's start 🚀

Zoom

To be able to interact when we are not in the same physical room, we will be using Zoom, a video conferencing tool.

⚠️ If you already have Zoom installed, please make sure that the version is at least 5.6.

Go to zoom.us/download.

Under Zoom Client click the Download button.

Open the file you have just downloaded to install the app.

Open the Zoom app.

If you already have a Zoom account, sign in using your credentials.

If not, click on the Sign Up Free link:

You will be redirected to Zoom's website to complete a form.

When it's done, go back to the Zoom app and sign in using your credentials.

You should then see a screen like this:

You can now close the Zoom app.

Chrome - your browser

Install the Google Chrome browser if you haven't got it already and set it as a default browser.

Follow the steps for your system from this link 👉 Install Google Chrome

Why Chrome?

We recommend to use it as your default browser as it's most compatible with testing or running your code, as well as working with Google Cloud Platform. Another alternative is Firefox, however we don't recommend using other tools like Opera, Internet Explorer or Safari.

GitHub account

Have you signed up to GitHub? If not, do it right away.

👉 Upload a picture and put your name correctly on your GitHub account. This is important as we'll use an internal dashboard with your avatar. Please do this now, before you continue with this guide.

SSH key

We want to safely communicate with your virtual machine using SSH protocol. We need to generate a SSH key to authenticate.

• Open your terminal

💡 Windows tip

We highly recommend installing Windows Terminal from the Windows Store (installed on Windows 11 by default) to perform this operation

• Create a SSH key

MacOS & Linux

EMAIL="[email protected]" # replace with your GCP account email
ssh-keygen -t ed25519 -C $EMAIL

Windows

EMAIL="[email protected]" # replace with your GCP account email
ssh-keygen.exe -t ed25519 -C $EMAIL

You should get the following message: > Generating public/private algorithm key pair.

• When you are prompted > Enter a file in which to save the key, press Enter
• You should be asked to Enter a passphrase, type a secure passphrase, it is like a password, but longer.

ℹ️ Don't worry if nothing prompt when you type, that is perfectly normal for security reasons.

• You should be asked to Enter same passphrase again, do it.

❗️ You must remember this passphrase.

Google Cloud Platform setup

GCP is a cloud solution that you are going to use in order to work on a virtual machine.

Project setup

👌 Note: Skip to the next section if you already have a GCP project

• Go to Google Cloud and create an account if you do not already have one
• In the Cloud Console, on the project list, select or create a Cloud project

• Give it a name such as Wagon Bootcamp for example
• Notice the ID automatically created for the project, e.g. wagon-bootcamp-123456

Account language

In order to facilitate the following of the instructions during the bootcamp, open your GCP account preferences:

https://myaccount.google.com/language

If the preferred language is not:

• English
• United States

Then switch the language to english:

• Click on the edit pen logo
• Select English
• Select United States
• Click on Select

Billing account

👌 Note: Skip to the next section if you already have a valid billing account

You will now link your account to your credit card. This step is required or you will not be able to use the services provided by GCP. Do not worry, you will be able to consume most GCP services through free credits throughout the bootcamp.

• Click on Billing
• Click on MANAGE BILLING ACCOUNTS
• Click on ADD BILLING ACCOUNT
• Give a name to your billing account, e.g. My Billing Account
• Click on "I have read..." and agree the to the terms of service
• Click on CONTINUE
• Select your account type: Individual
• Fill your name and address

You should see that you have a free credit of "$300 credits over the next 90days".

• Click on card details
• Enter your credit card info
• Click on START MY FREE TRIAL

Once this is done, verify that your billing account is linked to your GCP project.

• Select your project
• Go to Billing
• Select LINK A BILLING ACCOUNT
• Select My Billing Account
• Click on SET ACCOUNT

You should now see:

Free trial status: $300 credit and 91 days remaining - with a full account, you'll get unlimited access to all of Google Cloud Platform.

👉 If you do not own a credit card 👈

If you do not own a credit card, an alternative is to setup a Revolut account. Revolut is a financial app that will allow you to create a virtual credit card linked to your mobile phone billing account.

Skip this step if you own a credit card and use your credit card for the setup.

Download the Revolut app, or go to revolut and follow the steps to download the app (enter your mobile phone number and click on Get Started).

• Open the Revolut app
• Enter your mobile phone number
• Enter the verification code received by SMS
• The app will ask for your country, address, first and last name, date of birth, email address
• The app will also ask for a selfie and request your profession
• The app will require a photo of your identification card or passport

Once this is done, select the standard (free) plan. No need to add the card to Apple pay, or ask for a the delivery of a physical card, or add money securely.

You now have a virtual card which we will use for the GCP setup.

In the main view of the Revolut the app

• Click on Ready to use
• Click on the card
• Click on Show card details
• Note down the references of the virtual credit card and use them in order to proceed with the GCP setup

👉 If you receive an email from Google saying "Urgent: your billing account XXXXXX-XXXXXX-XXXXXX has been suspended" 👈

This may happen especially in case you just setup a Revolut account.

• Click on PROCEED TO VERIFICATION
• You will be asked to send a picture of your credit card (only the last 4 digits, no other info)
• In case you used Revolut, you can send a screenshot of your virtual credit card (do not forget to remove the validity date from the screenshot)
• Explain that you are attending the Le Wagon bootcamp, do not own a credit card, and have just created a Revolut account in order to setup GCP for the bootcamp using a virtual credit card

You may receive a validation or requests for more information within 30 minutes.

Once the verification goes through, you should receive an email stating that "Your Google Cloud Platform billing account XXXXXX-XXXXXX-XXXXXX has been fully reinstated and is ready to use.".

GCP APIs

You will use different GCP services during the bootcamp which needs to be activated and configured.

Default APIs

Go to your project APIs dashboard, you can see a bunch of APIs are already enabled:

Enable Compute Engine (virtual machines) API

👌 Note: Skip to the next section if you already have Compute Engine enabled

• In the search bar, type compute and click on the Compute Engine result

• Click on ENABLE

  

• Compute Engine is now enabled on your project

Virtual Machine (VM)

👌 Note: Skip to the next section if you already have a VM set up

Note: The following section requires you already have a Google Cloud Platform account associated with an active Billing account.

• Go to console.cloud.google.com > > Compute Engine > VM instances > Create instance

• Name it lewagon-data-eng-vm-<github_username>, replace <github_username> with your own, e.g. krokrob

• Region europe-west1, choose the closest one among the available regions

  

• In the section Machine configuration

• Select General purpose > e2-standard-4

  

• Boot disk > Change

  • Operating system > Ubuntu

  • Version > Ubuntu 22.04 LTS

  • Boot disk type > Balanced persistent disk

  • Size > upgrade to 150GB

    

• Open Networking, Disks, ...

• Open Networking

  

• Go to Network interfaces and click on default default (...) with a downward arrow on the right.

  

• This opened a box Edit network interface

• Go to the dropdown External IPv4 address, click on it, click on CREATE IP ADDRESS

  

• Give it a name, like "lewagon-data-eng-vm-ip-<github_username>" (replace <github_username> with your own) and description "Le Wagon - Data Engineering VM IP". This will take a few seconds.

  

• You will now have a public IP associated with your account, and later to your VM instance. Click on Done at the bottom of the section Edit network interface you were in.

  

Public SSH key

• Open the Security section

  

• Open the Manage access subsection

  

• Go to Add manually generated SSH keys and click Add item

  

• In your terminal display your public SSH key:

  cat ~/.ssh/id_ed25519.pub

• Copy your public SSH key and paste it:

  

• On the right hand side you should see

  

• You should be good to go and click CREATE at the bottom

  

• It will take a few minutes for your virtual machine (VM) to be created. Your instance will show up like below when ready, with a green circled tick, named lewagon-data-eng-vm-krokrob (krokrob being replaced by your GitHub username).

  

• Click on your instance

  

• Go down to the section SSH keys, and write down your username

  

Congrats, your virtual machine is up and running, it is time to connect it with VS Code!

Visual Studio Code

Installation

Let's install Visual Studio Code text editor.

• Go to Visual Studio Code download page.
• Click on "Windows" button
• Open the file you have just downloaded.
• Install it with few options:

When the installation is finished, launch VS Code.

VS Code Remote SSH Extension

We need to connect VS Code to a virtual machine in the cloud so you will only work on that machine during the bootcamp. A pretty useful Remote SSH Extension is available on the VS Code Marketplace.

• Open VS Code > Open the command palette > Type Extensions: Install Extensions

• Install the extension

That's the only extension you should install on your local machine, we will install additional VS Code extensions on your virtual machine.

Virtual Machine connexion

• Open VS Code > Open the command palette > Type Remote-SSH: Connect to Host...

• Click on Add a new host
• Type ssh -i <path/to/your/private/key> <username>@<ip address>, for instance, my username is somedude, and private key at ~/.ssh/id_rsa, with a public IP of 34.77.50.76, I'll type ssh -i ~/.ssh/id_rsa [email protected]

• When prompted to Select SSH configuration file to update, pick the one in your home directory, under the .ssh folder, ~/.ssh/config basically. Usually VS Code will pick automatically the best option, so their default should work.

• You should get a pop-up on the bottom right notifying you the host has been added

• Open again the command palette > Type Remote-SSH: Connect to Host... > Pick your VM IP address

• The first time, VSCode might ask you for a security permission like below, say yes / continue.

• Open again the command palette > Type Terminal: Create New Terminal (in active workspace) > You now have a Bash terminal in your virtual machine!

• Lets create a more readable version of your machine to connect to!

Lets go to the ssh config

code ~/.ssh/config

You should see something like the following:

Host <machine ip>
  HostName <machine ip>
  IdentityFile <file path for your ssh key>
  User <username>

You can now change Host to whatever you would like to see as the name of your connection or in terminal with ssh <Host>!

# For instance
Host "data engineering bootcamp"
  HostName 35.240.107.210
  IdentityFile <file path for your ssh key>
  User <username>

ℹ️ From now on, the setup of your local machine is over. The following steps aim at configuring your virtual machine.

VS Code Extensions

Installation

Let's install some useful extensions to VS Code.

code --install-extension ms-vscode.sublime-keybindings
code --install-extension emmanuelbeziat.vscode-great-icons
code --install-extension MS-vsliveshare.vsliveshare
code --install-extension ms-python.python
code --install-extension KevinRose.vsc-python-indent
code --install-extension ms-python.vscode-pylance
code --install-extension ms-toolsai.jupyter

Here is a list of the extensions you are installing:

• Sublime Text Keymap and Settings Importer
• VSCode Great Icons
• Live Share
• Python
• Python Indent
• Pylance
• Jupyter

Command line tools

Zsh & Git

Instead of using the default bash shell, we will use zsh.

We will also use git, a command line software used for version control.

Let's install them, along with other useful tools:

• Open an Ubuntu terminal
• Copy and paste the following commands:

sudo apt update

sudo apt install -y curl git imagemagick jq unzip vim zsh tree

These commands will ask for your password: type it in.

⚠️ When you type your password, nothing will show up on the screen, that's normal. This is a security feature to mask not only your password as a whole but also its length. Just type in your password and when you're done, press Enter.

GitHub CLI installation

Let's now install GitHub official CLI (Command Line Interface). It's a software used to interact with your GitHub account via the command line.

In your terminal, copy-paste the following commands and type in your password if asked:

sudo apt remove -y gitsome # gh command can conflict with gitsome if already installed
curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | sudo dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" | sudo tee /etc/apt/sources.list.d/github-cli.list > /dev/null
sudo apt update
sudo apt install -y gh

To check that gh has been successfully installed on your machine, you can run:

gh --version

✔️ If you see gh version X.Y.Z (YYYY-MM-DD), you're good to go 👍

❌ Otherwise, please contact a teacher

Oh-my-zsh

Let's install the zsh plugin Oh My Zsh.

In a terminal execute the following command:

sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

If asked "Do you want to change your default shell to zsh?", press Y

At the end your terminal should look like this:

✔️ If it does, you can continue 👍

❌ Otherwise, please ask for a teacher

direnv

direnv is a shell extension. It makes it easy to deal with per project environment variables. This will be useful in order to customize the behavior of your code.

sudo apt-get update; sudo apt-get install direnv
echo 'eval "$(direnv hook zsh)"' >> ~/.zshrc

GitHub CLI

CLI is the acronym of Command-line Interface.

In this section, we will use GitHub CLI to interact with GitHub directly from the terminal.

It should already be installed on your computer from the previous commands.

First in order to login, copy-paste the following command in your terminal:

⚠️ DO NOT edit the email

gh auth login -s 'user:email' -w

gh will ask you few questions:

What is your preferred protocol for Git operations? With the arrows, choose SSH and press Enter. SSH is a protocol to log in using SSH keys instead of the well known username/password pair.

Generate a new SSH key to add to your GitHub account? Press Enter to ask gh to generate the SSH keys for you.

If you already have SSH keys, you will see instead Upload your SSH public key to your GitHub account? With the arrows, select your public key file path and press Enter.

Enter a passphrase for your new SSH key (Optional). Type something you want and that you'll remember. It's a password to protect your private key stored on your hard drive. Then press Enter.

⚠️ When you type your passphrase, nothing will show up on the screen, that's normal. This is a security feature to mask not only your passphrase as a whole but also its length. Just type your passphrase and when you're done, press Enter.

You will then get the following output:

! First copy your one-time code: 0EF9-D015
- Press Enter to open github.com in your browser...

Select and copy the code (0EF9-D015 in the example), then press Enter.

Your browser will open and ask you to authorize GitHub CLI to use your GitHub account. Accept and wait a bit.

Come back to the terminal, press Enter again, and that's it.

To check that you are properly connected, type:

gh auth status

✔️ If you get Logged in to github.com as <YOUR USERNAME> , then all good 👍

❌ If not, contact a teacher.

Google Cloud CLI

Install the gcloud CLI to communicate with Google Cloud Platform through your terminal:

echo "deb [signed-by=/usr/share/keyrings/cloud.google.gpg] https://packages.cloud.google.com/apt cloud-sdk main" | sudo tee -a /etc/apt/sources.list.d/google-cloud-sdk.list
sudo apt-get install apt-transport-https ca-certificates gnupg
curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key --keyring /usr/share/keyrings/cloud.google.gpg add -
sudo apt-get update && sudo apt-get install google-cloud-sdk
sudo apt-get install google-cloud-sdk-app-engine-python

Create a service account key 🔑

👌 Note: Skip to the next section if you already have a service account key

Now that you have created a GCP account and a project (identified by its PROJECT_ID), we are going to configure the actions (API calls) that you want to allow your code to perform.

🤔 Why do we need a service account key ?

You have created a GCP account linked to your credit card. Your account will be billed according to your usage of the ressources of the Google Cloud Platform. The billing will occur if you consume anything once the free trial is over, or if you exceed the amount of spending allowed during the free trial.

In your GCP account, you have created a single GCP project, identified by its PROJECT_ID. The GCP projects allow you to organize and monitor more precisely how you consume the GCP ressources. For the purpose of the bootcamp, we are only going to create a single project.

Now, we need a way to tell which ressources within a GCP project our code will be allowed to consume. Our code consumes GCP ressources through API calls.

Since API calls are not free, it is important to define with caution how our code will be allowed to use them. During the bootcamp this will not be an issue and we are going to allow our code to use all the API of GCP without any restrictions.

In the same way that there may be several projects associated with a GCP account, a project may be composed of several services (any bundle of code, whatever its form factor, that requires the usage of GCP API calls in order to fulfill its purpose).

GCP requires that the services of the projects using API calls are registered on the platform and their credentials configured through the access granted to a service account.

For the moment we will only need to use a single service and will create the corresponding service account.

Since the service account is what identifies your application (and therefore your GCP billing account and ultimately your credit card), you are going to want to be cautious with the next steps.

⚠️ Do not share you service account json file 🔑 ⚠️ Do not store it on your desktop, do not store it in your git codebase (even if your git repository is private), do not let it by the coffee machine, do not send it as a tweet.

• Go to the service accounts page
• Select your project in the list of recent projects if asked to
• Create a service account:
  • Click on CREATE SERVICE ACCOUNT:
  • Give a Service account name to that account
  • Click on CREATE AND CONTINUE
  • Click on Select a role and choose Quick access/Basic then Owner, which gives full access to all ressources
  • Click on CONTINUE
  • Click on DONE
• Download the service account json file 🔑:
  • Click on the newly created service account
  • Click on KEYS
  • Click on ADD KEY then Create new key
  • Select JSON and click on CREATE

The browser has now saved the service account json file 🔑 in your downloads directory (it is named according to your service account name, something like le-wagon-data-123456789abc.json)

Configure Cloud sdk

• Open the service account json file with any text editor and copy the key

  # It looks like:
  {
      "type": "service_account",
      "project_id": "kevin-bootcamp",
      "private_key_id": "1234567890",
      "private_key": "-----BEGIN PRIVATE KEY-----\nXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX\n-----END PRIVATE KEY-----\n",
      "client_email": "[email protected]",
      "client_id": "1234567890",
      "auth_uri": "https://accounts.google.com/o/oauth2/auth",
      "token_uri": "https://oauth2.googleapis.com/token",
      "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
      "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/bootcamp%40kevin-bootcamp.iam.gserviceaccount.com"
  }
  

• Create a ~/.gcp_keys directory on your Virtual Machine, then create a json file in it:

  mkdir ~/.gcp_keys
  touch ~/.gcp_keys/le-wagon-de-bootcamp.json

• Open the json file then store the service account json file pasting the key:

  code ~/.gcp_keys/le-wagon-de-bootcamp.json

  

  ❗️Don't forget to save the file with CMD + s or CTRL + s

• Authenticate the gcloud CLI with the google account you used for GCP

  # Replace service_account_name@project_id.iam.gserviceaccount.com with your own
  SERVICE_ACCOUNT_EMAIL=service_account_name@project_id.iam.gserviceaccount.com
  KEY_FILE=$HOME/.gcp_keys/le-wagon-de-bootcamp.json
  gcloud auth activate-service-account $SERVICE_ACCOUNT_EMAIL --key-file=$KEY_FILE

• List your active account and check your email address you used for GCP is present

  gcloud auth list

• Set your current project

  # Replace `PROJECT_ID` with the `ID` of your project, e.g. `wagon-bootcamp-123456`
  gcloud config set project PROJECT_ID

• List your active account and current project and check your project is present

  gcloud config list

Dotfiles

There are three options, choose one:

I already attended Web Development (FullStack) bootcamp at Le Wagon on the same laptop

This means that you already forked the GitHub repo lewagon/dotfiles, but at that time the configuration was maybe not ready for the new Data Science bootcamp.

Open your terminal and go to your dotfiles project:

cd ~/code/<YOUR_GITHUB_NICKNAME>/dotfiles
code . # Open it in VS Code

In VS Code, open the zshrc file. Replace its content with the newest version of that file that we provide. Save to disk.

Back to the terminal, run a git diff and ask a TA to come and check about this configuration change. You should see stuff about Python and pyenv.

Once this is good, commit and push your changes:

git add zshrc
git commit -m "Update zshrc for Data Science bootcamp"
git push origin master

OR

I did not attend the Web Dev bootcamp at Le Wagon

Hackers love to refine and polish their shell and tools. We'll start with a great default configuration provided by Le Wagon, stored on GitHub. As your configuration is personal, you need your own repository storing it, so you first need to fork it to your GitHub account.

➡️ Click here to fork the lewagon/dotfiles repository to your account (you'll need to click again on your picture to confirm where you do the fork).

Forking means that it will create a new repo in your GitHub account, identical to the original one. You'll have a new repository on your GitHub account, your_github_username/dotfiles. We need to fork because each of you will need to put specific information (e.g. your name) in those files.

Open your terminal and run the following command:

export GITHUB_USERNAME=`gh api user | jq -r '.login'`
echo $GITHUB_USERNAME

You should see your GitHub username printed. If it's not the case, stop here and ask for help. There seems to be a problem with the previous step (gh auth).

Time to fork the repo and clone it on your laptop:

mkdir -p ~/code/$GITHUB_USERNAME && cd $_
gh repo fork lewagon/dotfiles --clone

Run the dotfiles installer.

cd ~/code/$GITHUB_USERNAME/dotfiles && zsh install.sh

Check the emails registered with your GitHub Account. You'll need to pick one at the next step:

gh api user/emails | jq -r '.[].email'

Run the git installer:

cd ~/code/$GITHUB_USERNAME/dotfiles && zsh git_setup.sh

☝️ This will prompt you for your name (FirstName LastName) and your email. Be careful you need to put one of the email listed above thanks to the previous gh api ... command. If you don't do that, Kitt won't be able to track your progress.

Please now quit all your opened terminal windows.

OR

I already attended Web Development (FullStack) bootcamp at Le Wagon but I have a new laptop

Open your terminal and run the following command:

export GITHUB_USERNAME=`gh api user | jq -r '.login'`
echo $GITHUB_USERNAME

You should see your GitHub username printed. If it's not the case, stop here and ask for help. There seems to be a problem with the previous step (gh auth).

Time to fork the repo and clone it on your laptop:

mkdir -p ~/code/$GITHUB_USERNAME && cd $_
gh repo fork lewagon/dotfiles --clone

Run the dotfiles installer.

cd ~/code/$GITHUB_USERNAME/dotfiles && zsh install.sh

Check the emails registered with your GitHub Account. You'll need to pick one at the next step:

gh api user/emails | jq -r '.[].email'

Run the git installer:

cd ~/code/$GITHUB_USERNAME/dotfiles && zsh git_setup.sh

☝️ This will prompt you for your name (FirstName LastName) and your email. Be careful you need to put one of the email listed above thanks to the previous gh api ... command. If you don't do that, Kitt won't be able to track your progress.

Please now quit all your opened terminal windows.

zsh default terminal

Set zsh as your default VS Code terminal.

• Open terminal default profile settings

  

• Select zsh /usr/bin/zsh

  

Disable SSH passphrase prompt

You don't want to be asked for your passphrase every time you communicate with a distant repository. So, you need to add the plugin ssh-agent to oh my zsh:

First, open the .zshrc file:

code ~/.zshrc

Then:

• Spot the line starting with plugins=
• Add ssh-agent at the end of the plugins list

The list should look like:

plugins=(gitfast last-working-dir common-aliases zsh-syntax-highlighting history-substring-search pyenv ssh-agent)

✔️ Save the .zshrc file with Ctrl + S and close your text editor.

Installing Python (with pyenv)

Ubuntu comes with an outdated version of Python that we don't want to use. You might already have installed Anaconda or something else to tinker with Python and Data Science packages. All of this does not really matter as we are going to do a professional setup of Python where you'll be able to switch which version you want to use whenever you type python in the terminal.

First let's install pyenv with the following Terminal command:

git clone https://github.com/pyenv/pyenv.git ~/.pyenv
exec zsh

Let's install some dependencies needed to build Python from pyenv:

sudo apt-get update; sudo apt-get install make build-essential libssl-dev zlib1g-dev \
libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm \
libncursesw5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev \
python3-dev

Let's install the latest stable version of Python supported by Le Wagon's curriculum:

pyenv install 3.10.6

This command might take a while, this is perfectly normal. Don't hesitate to help other students seated next to you!

OK once this command is complete, we are going to tell the system to use this version of Python by default. This is done with:

pyenv global 3.10.6
exec zsh

To check if this worked, run python --version. If you see 3.10.6, perfect! If not, ask a TA that will help you debug the problem thanks to pyenv versions and type -a python (python should be using the .pyenv/shims version first).

Python Virtual Environment

Before we start installing relevant Python packages, we will isolate the setup for the Bootcamp into a dedicated virtual environment. We will use a pyenv plugin called pyenv-virtualenv.

First let's install this plugin:

git clone https://github.com/pyenv/pyenv-virtualenv.git $(pyenv root)/plugins/pyenv-virtualenv
exec zsh

Let's create the virtual environment we are going to use during the whole bootcamp:

pyenv virtualenv 3.10.6 lewagon

Let's now set the virtual environment with:

pyenv global lewagon

Great! Anytime we'll install Python package, we'll do it in that environment.

Python packages

Now that we have a pristine lewagon virtual environment, it's time to install some packages in it.

First, let's upgrade pip, the tool to install Python Packages from pypi.org. In the latest terminal where the virtualenv lewagon is activated, run:

pip install --upgrade pip

Then let's install some packages for the first weeks of the program:

pip install -r https://raw.githubusercontent.com/lewagon/data-setup/master/specs/releases/linux.txt

jupyter notebook extensions

Pimp your jupyter notebooks with awesome extensions:

# install nbextensions
jupyter contrib nbextension install --user
jupyter nbextension enable toc2/main
jupyter nbextension enable collapsible_headings/main
jupyter nbextension enable spellchecker/main
jupyter nbextension enable code_prettify/code_prettify

Custom CSS

Improve the display of the details disclosure elements in your notebooks.

Open custom/custom.css in the config directory:

cd $(jupyter --config-dir)
mkdir -p custom
touch custom/custom.css
code custom/custom.css

Edit custom.css with:

summary {
    cursor: pointer;
    display:list-item;
}
summary::marker {
    font-size: 1em;
}

You can close VS Code.

jupyter check up

Let's reset your terminal:

exec zsh

Now, check you can launch a notebook server on your machine:

jupyter notebook

Your web browser should open on a jupyter window:

Click on New:

A tab should open on a new notebook:

nbextensions check up

Perform a sanity check for jupyter notebooks nbextensions. Click on Nbextensions:

Untick "disable configuration for nbextensions without explicit compatibility" then check that at least all nbextensions circled in red are enabled:

You can close your web browser then terminate the jupyter server with CTRL + C.

Python setup check up

Check your Python version with the following commands:

zsh -c "$(curl -fsSL https://raw.githubusercontent.com/lewagon/data-setup/master/checks/python_checker.sh)" 3.10.6

Run the following command to check if you successfully installed the required packages:

zsh -c "$(curl -fsSL https://raw.githubusercontent.com/lewagon/data-setup/master/checks/pip_check.sh)"

Now run the following command to check if you can load these packages:

python -c "$(curl -fsSL https://raw.githubusercontent.com/lewagon/data-setup/master/checks/pip_check.py)"

Make sure you can run Jupyter:

jupyter notebook

And open a Python 3 notebook.

Make sure that you are running the correct python version in the notebook. Open a cell and run :

import sys; sys.version

Here you have it! A complete python virtual env with all the third-party packages you'll need for the whole bootcamp.

DBeaver

Download and install DBeaver, a free and open source powerful tool to connect to any database, explore the schema and even run SQL queries.

Kitt

⚠️ If you have received an email from Le Wagon inviting you to sign up on Kitt (our learning platform), you can safely skip this step. Instead, please follow the instructions in the email you received if you haven't done so already.

If you are unsure about what to do, you can follow this link. If you are already logged in, you can safely skip this section. If you are not logged in, click on Enter Kitt as a Student. If you manage to login, you can safely skip this step. Otherwise ask a teacher whether you should have received an email or follow the instructions below.

Register as a Wagon alumni by going to kitt.lewagon.com/onboarding. Select your batch, sign in with GitHub and enter all your information.

Your teacher will then validate that you are indeed part of the batch. You can ask him to do it as soon as you completed the registration form.

Once the teacher has approved your profile, go to your email inbox. You should have 2 emails:

• One from Slack, inviting you to the Le Wagon Alumni slack community (where you'll chat with your buddies and all the previous alumni). Click on Join and fill the information.
• One from GitHub, inviting you to lewagon team. Accept it otherwise you won't be able to access the lecture slides.

Slack

Slack is a communcation platform pretty popular in the tech industry.

Installation

Download the Slack app and install it.

⚠️ If you are already using Slack in your browser, please download and install the desktop app which is fully featured.

Settings

Launch the app and sign in to lewagon-alumni organization.

Make sure you upload a profile picture 👇

The idea is that you'll have Slack open all day, so that you can share useful links / ask for help / decide where to go to lunch / etc.

To ensure that everything is working fine for video calls, let's test your camera and microphone:

• Open the Slack app
• In any channel message bar type /call --test and press Enter
• Click on the "Start test" green button

✔️ When the test is finished, you should see green "Succeed" messages at least for your microphone and camera. 👍

❌ If not, contact a teacher.

You can also install Slack app on your phone and sign in lewagon-alumni!

(Bonus) Kata

If you are done with your setup, please ask around if some classmates need some help with theirs (macOS, Linux, Windows). We will have our first lectures at 2pm and will talk about the Setup you just did + onboard you on Kitt.

If you don't have a lot of experience with git and GitHub, please (re-)watch this workshop (1.25 playback speed is fine).

If you do, then you can wait for the first lecture working on this Tic-Tac-Toe Kata
