Python venv virtual environment cheat sheet

Create a venv

To create a virtual environment, go to the root of your project and run

python -m venv venv

It will create a virtual environment called venv

Activate venv

.\venv\Scripts\activate

Intall packages

pip install jupyter matplotlib numpy pandas scipy scikit-learn

or

python -m pip install -U jupyter matplotlib numpy pandas scipy scikit-learn

Create requirements.txt

pip freeze > requirements.txt

Deactivate venv

deactivate

Install packages from requirements.txt

pip install -r requirements.txt

Place the requirements.txt file in the root of your project directory. When ready to install the dependencies, ensure your terminal is navigated to the project directory and your virtual environment is activated. Then, run pip install -r requirements.txt to install the listed packages within your virtual environment.

Pasting these 3 for even easier access:

python -m venv venv
.\venv\Scripts\activate
pip install -r requirements.txt

also specify where we should paste the requirements.txt file before executing this command

Place the requirements.txt file in the root of your project directory. When ready to install the dependencies, ensure your terminal is navigated to the project directory and your virtual environment is activated. Then, run pip install -r requirements.txt to install the listed packages within your virtual environment. I updated the original text to include this.
