To specify a Python version in a Conda environment, you can create a new environment or modify an existing one with the desired version of Python using the
conda create or
conda env update command.
- Creating a new environment:
To create a new environment with a specific version of Python, you can use the following command:
conda create --name myenv python=3.8
This creates a new environment called
myenv with Python 3.8 installed.
- Updating an existing environment:
To update an existing environment with a specific version of Python, you can create an
environment.yml file with the desired configuration and run the
conda env update command. Here’s an example
name: myenv channels: - defaults dependencies: - python=3.8
Save this file in your project directory and then run the following command:
conda env update --file environment.yml
This updates the
myenv environment with Python 3.8.
You can then activate the environment with the following command:
conda activate myenv
This activates the
myenv environment with the specified version of Python.
Note that when you create or update a Conda environment with a specific version of Python, Conda will also install any required packages and dependencies for that version of Python.
