In my previous blog , I walked you through all steps to run a jupyter notebook. If you’re a data scientist or developer and upgraded to macOS Catalina 10.15, then you might have faced some issues with jupyter notebook.The latest version of Mac Catalina functionality is different than the previous s version. Follow below steps to configure and run jupyter notebook.

MacOS Catalina is not supported. CodeWeavers, with support from Wargaming, has developed a software solution that allows macOS users to join World of Warships. In order to do this, you need to.

For example, if you want to easily install favorite command line tools on a Mac like cask, htop, wget, nmap, tree, irssi, links, colordiff, or virtually any other familiar unix command line utility, you can do so with a simple command. Under the pop-up menu, you’ll see Select the OS X installer. (macOS used to be called OS X.) If you have only the Catalina installer on your Mac, Install Disk Creator will automatically.

We will go through each step one by one configure jupyter notebook.

Step I : Install the anaconda distribution.

The preferable way to go forward is to use command line installer instead of graphic . Use this link to download CLI https://repo.anaconda.com/archive/Anaconda3-2020.02-MacOSX-x86_64.sh

Once downloaded ,go to terminal and run

I will be using python3 as python2 is not much in use now a days.

To start the installation run below command in your terminal.

Instead of Downloads use the path where you have install anaconda distribution and replace Anaconda3–2020.02-MacOSX-x86_64.sh with your filename.

You need to press Enter here ,

Read the license agreement and scroll to bottom

Enter yes. Next it will ask for location to install.

Press Enter .

Once you press enter , message props “Do you wish the installer to initialize Anaconda3 by running conda init?”

Enter Yes

The default shell for Catalina is zsh so our next step will be to install Zsh

Step II :Set-up macOs Terminal with Zsh

For Catalina

First set-up Xcode command-line tools, also known as xcode-select

If there is some issue try running below script.

Then you need to install software package management system for macOS i.e Homebrew.

Run the below command

Next step is to install default shell for Catalina ,i.e zsh.

Now we need to integrate zsh in iterm2. If you are not having iterm2 ,install it using brew.

For zsh — iterm2 integration ,

Step III :Conda ,Pip and Jupyter installation

Conda can be installed using brew

Update conda to latest version

Update Anaconda Mac

For pip you can either use conda or easy install

Conda way

Easy install way

For nbextensions run following command

Install Anaconda Mac Os

Lastly for jupyter use brew

Anaconda Download Mac Os Catalina Dmg

Step IV :Creating Virtual environment and link it to ipykernel

To create a virtual environment pass the name of environment with python version to be used. Suppose we name our environment as cat and want to use python 3.8.2 version.

Activate the environment

Install ipykernel

Anaconda Download Macos Catalina

Link kernel to virtual environment.

If you want to display the name of environment say “Cat_Virtual”

Go to iterm2 and run

Open any notebook , it will appear like this,

Enjoy 😊 !!
