Introduction

I couldn't find any good material (not too much information, not too little information) about how to use Anaconda (conda command), so I summarized it.

This article assumes that you have Anaconda installed.

You can check the installation with the following command.

$ conda --version
conda 4.8.2

For Jupyter notebook, you can check it in the same way by executing the cell with ! Conda --version and ! at the beginning of the command on the Python cell.

What is Anaconda?

A collection of Python packages for data science --Supports over 1,500 packages --Supports both GUI and command line --Can be operated using the conda command

By using Anaconda, it is possible to easily build and switch the development environment without taking time to install the library.

Notes on how to use Anaconda (conda command)

1. Building a virtual environment with conda

$ conda create --name my_notebook_env python=3.7 -y

-name my_notebook_env: The name of the virtual environment. You can set whatever you like. python = 3.7: Python version used in the virtual environment -y: Automatically respond to confirmation items with yes

2. Enable virtual environment

Enable virtual environment

$ conda activate my_notebook_env

Disable virtual environment

$ conda deactivate

Delete virtual environment

$ conda remove --name my_notebook_env --all

3. Installing libraries in a virtual environment

To install pandas

$ conda install pandas

To install jupyter

$ conda install jupyter

View a list of installed libraries

$ conda list

Example: Launch jupyter notebooks in a virtual environment

Activate the virtual environment and launch jupyter notebooks

$ conda activate my_notebook_env
$ jupyter notebook

Summary

With Anaconda, you can easily build and switch development environments! Also, if the environment is damaged, you can easily rebuild it, so you can rest assured!
