Conda Install from Yaml - Shell-Bash

Conda is a package management system that allows you to easily install, manage, and update software packages. It is particularly popular in the data science and scientific computing communities due to its support of multiple programming languages and ability to manage complex dependencies.

One of the key features of Conda is the ability to create environments. Each environment is a self-contained installation of packages, with its own independent dependencies. This makes it easy to manage different projects with different requirements.

One way to create an environment in Conda is to define it using a YAML file. The YAML file specifies the name of the environment, the packages to be installed, and any specific version requirements or constraints.

To install packages from a YAML file in the Conda environment using Shell-Bash, follow these steps:

1. Create a YAML file: Create a YAML file with the required packages and versions. For example, create a file called my_env.yaml with the following contents:

name: my_env
dependencies:
  - python=3.6
  - numpy
  - pandas=0.23.4
  - scikit-learn=0.20.0

2. Activate your Conda environment: Open your terminal window and activate your Conda environment using the following command:

conda activate my_env

3. Install packages from YAML file: Once you’ve activated your environment, run the following command to install packages from the YAML file:

conda env update --file my_env.yaml

This will install all the packages in the YAML file into your environment, including any dependencies.

4. Verify installed packages: After installation, verify that the packages have been installed in the environment by running conda list.

conda list

You should see a list of packages that were installed in your environment.

Overall, using a YAML file to install packages in a Conda environment is an efficient and convenient way to manage your dependencies. It makes it easy to specify the exact packages and versions needed for your projects, and ensures that they are installed correctly.
