Post-Installation Steps#

Hint

To maintain a clean setup, clone the base environment right after installation and create a separate environment, conda create --name <myenv> --clone base. This practice helps to avoid any modifications or conflicts in the base environment. To make it foolproof, adjust your .bashrc configuration as described in the steps below.

Command

Description

conda --version

Check current Anaconda version

conda update conda

Update Conda to the latest version

conda create --name <myenv> --clone base

Clone the base environment

conda list

Verify installation by showing a list of installed packages

Remember, you should restart the terminal after installing Anaconda. In some cases, changes might not take effect until the system is restarted.


Configuring the .bashrc File#

After setting up a working Anaconda environment, it’s is also recommended to configure the .bashrc file for Conda.

Step 1: Open .bashrc#

Open the .bashrc file in your home directory using a text editor. In this case, Nano is used.

Terminal#
  nano ~/.bashrc

Step 2: Insert Conda Configuration#

At the end of the file, insert the following Conda configuration:

Terminal#
  # <<< conda initialize <<<
  
  # Conda config
  conda deactivate
  conda activate baseclone

By adding these lines to your .bashrc file, you ensure that every time a new bash session starts, it will initialize Conda and activate the <myenv> environment.

Step 3: Save and Exit Nano#

While in Nano editor, you can save your changes and exit by using the following shortcuts:

Terminal#
   `Ctrl + O`           # to save the file.
   
   `Ctrl + X`           # to exit the nano editor.

After saving the changes and closing the .bashrc file, you may need to restart your terminal for the changes to take effect.
