3) Adding packages to Anaconda

Anaconda comes with many pre-installed packages, but you may need to add additional packages to your Anaconda installation to suit your particular data science or machine learning needs. There are two primary ways to install additional packages in Anaconda: using conda-forge and using pip.

Installing packages using conda-forge:

Conda-forge is a community-driven platform that provides a wide range of packages that you can use to extend the functionality of Anaconda. Adding packages to your Anaconda installation using conda-forge is relatively straightforward.

Heres how to do it:

1. Open the Anaconda Navigator and click on the Environments tab.

2. Choose the environment that you would like to add packages to or create a new environment.

3. In the search bar, type the name of the package you want to add and press enter.

4. All available packages related to the search term on conda-forge will appear.

Choose the package that you want and click the button labeled “Apply”. The system will then check for package dependencies and dependencies, and once complete, install the packages selected.

Installing packages using pip:

Pip (Python Package Index) is a package manager for Python that enables the installation of packages not available on conda-forge. This makes it particularly useful when developing data science projects.

Heres how to use pip with Anaconda:

1. Open a command prompt or terminal.

2. Type “conda install pip” and press enter to install pip in your Anaconda environment.

3. Use the “pip install package_name” command to install any package not available in conda-forge.

It is vital to note that an alternative, more reliable way of using Pip with Anaconda is by using Pip inside a Conda environment and not as a system-level module. This ensures that Pip installed on the virtual environment will not conflict with the system Pip.

4) Understanding Virtual Environment

A virtual environment is an isolated environment that allows you to manage dependencies, packages, and other requirements for different projects without conflicts. It enables you to create and test new features without affecting the currently installed packages.

Here’s how to set up a virtual environment with Conda:

Setting up virtual environment with Conda Interface:

1. Open Anaconda Navigator and click on the Environments tab.

2. Scroll down to the bottom and click on the Create button to create a new environment.

3. Enter the name of the environment, select the Python version, and then click on the Create button.

4. Once the environment is created, click on the green arrow next to it and click on Open Terminal.

5. In the terminal, enter the following command to install additional packages in the new environment: “conda install package_name”.

Activating and deactivating virtual environment:

After successfully creating a virtual environment, you need to activate it to start using it. Heres how to activate and deactivate a virtual environment:

1.

Open a terminal. 2.

Activate the virtual environment by typing the following command: “conda activate environment_name”. 3.

To deactivate the environment, type the following command: “conda deactivate”. Deleting virtual environment:

To delete a virtual environment, open the Anaconda Navigator, select the Environments tab, and then click on the gear icon next to the environment you want to delete.

From the drop-down list, select Remove and confirm the action.
