Create Environment File

~/energy-forecasting $ cp .env.default .env

The command cp .env.default .env is used to create a copy of the .env.default file and name it .env. In many projects, the .env file is used to store environment variables that the application needs to run. The .env.default file is usually a template that includes all the environment variables that the application expects, but with default values. By copying it to .env, you can customize these values for your own environment.

Set Up the ML_PIPELINE_ROOT_DIR Variable

~/energy-forecasting $ export ML_PIPELINE_ROOT_DIR=$(pwd)

The command export ML_PIPELINE_ROOT_DIR=$(pwd) is setting the value of the ML_PIPELINE_ROOT_DIR environment variable to the current directory. In this context, $(pwd) is a command substitution that gets replaced with the output of the pwd command, which prints the path of the current directory. The export command then makes this variable available to child processes of the current shell.

In essence, ML_PIPELINE_ROOT_DIR is an environment variable that is set to the path of the current directory. This can be useful for scripts or programs that need to reference the root directory of the ML pipeline, as they can simply refer to ML_PIPELINE_ROOT_DIR instead of needing to know the exact path.

Install for Development

Create virtual environment:

~/energy-forecasting                  $ cd feature-pipeline && rm poetry.lock
~/energy-forecasting/feature-pipeline $ bash ../scripts/devops/virtual_environment/poetry_install.sh
~/energy-forecasting/feature-pipeline $ source .venv/bin/activate

1. We first navigate to the feature-pipeline directory and remove the poetry.lock file. This step is essential if we intend to add new dependencies to the pyproject.toml file, as it ensures that Poetry accurately resolves and installs the latest compatible versions of all dependencies.
2. We then execute the poetry_install.sh script. This script is responsible for creating the virtual environment and installing the project dependencies. Importantly, it also includes steps to resolve potential issues related to the macOS arm64 architecture.
3. Finally, we activate the virtual environment. This step provides an isolated workspace for our project, preventing conflicts between the project's dependencies and those installed globally on the system.

Usage for Development

To start the ETL pipeline run:

~/energy-forecasting/feature-pipeline $ python -m feature_pipeline.pipeline

To create a new feature view run:

~/energy-forecasting/feature-pipeline $ python -m feature_pipeline.feature_view

NOTE: Be careful to set the ML_PIPELINE_ROOT_DIR variable as explained in this section.
