Note: On Ubuntu, you may need to install the python3-venv package first.

Create a setup.sh script:

#!/bin/bash

# Create virtual environment
python3 -m venv myenv

# Activate virtual environment
source myenv/bin/activate

# Upgrade pip
pip install --upgrade pip

# Install dependencies
pip install -r requirements.txt

Create a requirements.txt file:

# List your project dependencies here
package_name1
package_name2

To prepare or activate:

./setup.sh

To deactivate the virtual environment:

deactivate
