Anaconda is an Open-Source distribution for Python & R programming languages. It is being used widely for Machine Learning, Data Science, etc. It has more than 1500 python/R data packages & is an industry-standard for developing, testing, and training on a single machine.
With anaconda’s conda, we can manage dependencies, libraries & environments. We can also use it with a number of applications like TensorFlow, Dask, Numba, Boken, Datashader, etc to develop and train machine learning and deep learning models or analyze data with scalability and performance or to visualize results.

We have already discussed how to install Conda (anaconda) on Ubuntu & on CentOS/RHEL. Lets now discuss some Conda commands that we can use for package management.
Conda Commands Cheat Sheet
Check conda version
# conda info
Install a Package
# conda install package_name
For example,
# conda install spyder
Once a package has been installed, we can start it from the terminal,
# spyder
Update a package
# conda update package_name
For example,
# conda update package_name
Update conda to the latest version
To update conda to the latest version, use
# conda update conda
Remove a package
# conda remove package_name
For example,
# conda remove spyder
Search a package
To look for a particular package, use the following command,
# conda search package_name
Create a new environment
# conda create –name env_name
For example, if we need to create a new environment & install another python version on it, like python 3.6, use the following command,
# conda create –name test_py36 python=3.6
This way we can maintain many versions of python on a single system. We can also create a new environment with a package installed,
# conda create –name jupyter-env jupyter
List all created environments
# conda env list
Activate an environment
To activate the created environment, use
# source activate test_py36
Deactivate an environment
To delete an environment, use the following command,
# source deactivate
List all packages installed in an environment
# conda list
Delete an environment
To delete an environment along with all installed packages, use
# conda remove –name test_py36
Make a clone of an environment
To create an exact copy of an environment, we can use the following command,
# conda create –clone test_py36 –name test_py36-2
Save an environment to a text file
This is sort of like a backup, we can save an environment to a text file, which can later be used to create a new environment. To create a text file,
# conda list –explicit > backup_test_py36.txt
Restore an environment from a text file
To restore the environment saved to a text file, use the following command,
# conda env create –file backup_test_py36.txt
Conda Help
To get help about a command use,
# conda –help
or we can also use it like,
# conda remove –help
