Conda

Managing envs

Conda allows to create separated environment setups to code in Python.

Create an env from scratch

To create an env with python version 3.6 run:

    conda create --name <env-name> python=3.6

Create an env from env file

It is possible to recreate an env setup, one will need to have a saved env file. For instance, suppose we have an env file env-file.txt, to recreate the env run:

    conda env create --file  <env-file>.txt 

It is possible to edit the env file to update package’s versions and env’s name

Clone an env

To clone an env run:

    conda create --clone <sourc-env> --name <dest-env> 

Save an env to file

To save an env to file run:

    conda list --explicit >  <env-name>.txt 

Delete an env

    conda env remove --name <env-name>

List existing envs

    conda env list

List installed packages of an env

    conda list --name <env-name>
