Instructions for Configuring Anaconda Environments in Ubuntu
Experience the benefits of setting up Anaconda environments on Ubuntu, where you can establish isolated Python environments to manage diverse versions of libraries and packages for various projects.
This ensures the preservation of project-specific configurations and coherence.
Delve into this section of the article for insights into creating and managing Anaconda environments.
Create a New Environment:
To create a new Anaconda environment, you’ll need to specify a name for the desired environment and the desired Python version. Therefore, examining the available Python versions is a crucial step.
To find out which Python versions are available, use the following command:
conda search “^python$”
Corresponding to the Anaconda version, you will have access to a set of Python package versions. Since Anaconda is used with Python 3 in this article, Python 3 package versions will be available.
Then, to create a new Anaconda environment using the desired Python version, run the following command:
conda create –name myenv python=python_version
Replace “myenv” with your desired environment name and “python_version” with the Python version you want, and type y to confirm the output and the information given about the packages that will be installed.
Activate the Environment:
To utilize the Anaconda environment you crafted in Ubuntu, activate the new environment by executing the following command:
conda activate myenv
Upon activating the new environment, your command prompt prefix will indicate your entry into the new environment.
Verify Python Version of the Environment:
To ensure whether the newly created environment is using your desired Python version or not, the following command is useful:
python –version
The previous command’s output displays the Python version used in the Anaconda environment.
Install Packages to Environment:
Every environment you create in Anaconda includes default packages such as openssl, ncurses, libedit, ca-certificates, sqlite, zlib, python, wheel, pip, and so on. After activating the new Anaconda environment, you can install specific packages in the new environment using the command conda install.
For example:
conda install numpy pandas matplotlib
Deactivate the Environment:
To return to the base environment and deactivate the current environment, use the following command:
conda deactivate
List Environments:
To check all the environments you have created, you can type the following command:
conda env list
This command outputs a list of created environments. Alternatively, you can use the following command to inspect all of the environments:
conda info –envs
In the output, the environment with an asterisk is the currently active environment.
Remove an Environment:
When you don’t need a specific environment to use in the project, you can remove it by running the following command:
conda env remove –name myenv
replace myenv with the environment name you want to remove.
Then, to confirm the removal of the specific environment, you can run the conda info --envs command.
Uninstalling Anaconda in Ubuntu
If you’ve determined that Anaconda is no longer required, uninstall it from your Ubuntu system with a few simple commands.
Begin by installing the anaconda-clean module to remove Anaconda configuration files from your system.
install anaconda-clean
After installing the anaconda-clean module, run the following command to delete all Anaconda-related files and directories:
anaconda-clean
To streamline the removal process of each Anaconda configuration file, add the ‘– yes’ option at the end of the command to eliminate the need for manual confirmation (‘y’ input).
Execute the following command to remove all pertinent directories for Anaconda:
rm -rf ~/anaconda3
To ensure the complete removal of Anaconda from your Ubuntu system, you can delete the PATH line that Anaconda added to your .bashrc file. First, access the content of the file using your preferred text editor:
nano ~/.bashrc
In the file’s content, look for Anaconda; after finding it, delete or comment out the Anaconda block. After editing the content, type “CTRL + X” to exit the file and save your changes by typing “y.”
As a result, you have now completely cleaned your Ubuntu system from the Anaconda program.
