Environment Manager - Conda

#setup #macos #windows #conda

If you are testing programmes or developping your own I strongly suggest to look after an environment manager. An easy way to install libraries into dedicated environments in isolation from each other, and to keep track of what is installed where. A whildely used environment manager is conda

Licence

Conda itself is open source and free, but the main installer miniconda and it's default package repository are managed by Anaconda. Those services required a licence fee for "for-profit organization with more than 200 total employees" see this blog for more info.

Install on Windows

Before reading this post, I suggest you follow Ubuntu on Windows (WSL).

  • Open 'Ubuntu'
  • Download Miniconda installer for Linux 
wget https://repo.anaconda.com/miniconda/Miniconda3-py39_4.12.0-Linux-x86_64.sh
Enter fullscreen mode Exit fullscreen mode
  • Install miniconda 
bash Miniconda3-py39_4.12.0-Linux-x86_64.sh
Enter fullscreen mode Exit fullscreen mode
  • Press Enter to continue
  • Press Space to read through the licence
  • Key 'yes' to accept the licence
  • Press Enter to install miniconda3
  • Key 'yes' to confirm installation
  • Quit and restart 'Ubuntu'

At this point you will find a new information in your prompt that indicate in which conda environment you are currently in.

Win base

Install on MacOS

Before reading this post, I suggest you follow Improved Shell (MacOS).

  • Open 'Terminal'
  • Install miniconda from Homebrew 
brew install --cask miniconda
Enter fullscreen mode Exit fullscreen mode
  • Initiate conda for your shell(s) 
conda init --all
Enter fullscreen mode Exit fullscreen mode
  • Quit and restart 'Terminal'

At this point you will find a new information in your prompt that indicate in which conda environment you are currently in.

macOS base

Usage

  • Update conda 
conda update -n base -c defaults conda
Enter fullscreen mode Exit fullscreen mode
  • Create a new environment 
conda create -n myEnvName
Enter fullscreen mode Exit fullscreen mode
  • Activate the environment 
conda activate myEnvName
Enter fullscreen mode Exit fullscreen mode
  • Install libraries You can find libraries and how to install them either on Anaconda or pip 
conda install ...
Enter fullscreen mode Exit fullscreen mode 
pip install ...
Enter fullscreen mode Exit fullscreen mode
  • List all libraries in the current environment 
conda list
Enter fullscreen mode Exit fullscreen mode
  • Exit an environment 
conda deactivate
Enter fullscreen mode Exit fullscreen mode
  • Remove an environment 
conda env remove -n myEnvName
Enter fullscreen mode Exit fullscreen mode
  • List the environements available 
conda env list
Enter fullscreen mode Exit fullscreen mode

Next, I suggest you follow Cross Platform, Cross Language Text Editor - VSCode.
