notebook-orchestration-and-execution-manager 0.2.27.13.1

A tool for orchestrating and executing Jupyter notebooks, enabling seamless parameter passing between notebooks.

notebook-orchestration-and-execution-manager

Orchestrate Jupyter notebooks by passing parameters dynamically between them. This solution enables seamless execution, where the output of one notebook becomes the input for the next. Includes automated execution, parameter injection, logging, and output management for streamlined workflows.

Notebook Execution and Variable Extraction

This project provides a Python class and workflow to manage the execution of Jupyter notebooks with parameters, extract variables and their values from executed notebooks, and display the results in a structured format.

Features

• Execute Jupyter Notebooks: Run Jupyter notebooks with specified parameters using papermill.
• Dynamic Parameter Passing: Pass custom parameters to notebooks during execution.
• Variable Extraction: Extract variable data (name, operation, and value) from executed notebook cells.
• Logging: Track execution steps with detailed logs.
• Directory Management: Automatically manage output directories for processed notebooks.

Requirements

• Python 3.6+
• Libraries: os, papermill, logging, ast, IPython

Install dependencies via pip:

pip install notebook-orchestration-and-execution-manager

Usage

1. Initialize the NotebookOrchestrationExecutionManager

Create an instance of NotebookOrchestrationExecutionManager, specifying the directory for processed notebooks.

from notebook_orchestration_execution_manager import NotebookOrchestrationExecutionManager

processor = NotebookOrchestrationExecutionManager(processed_directory="./processed_notebook")

1.1 Parameters Definition

How to Configure a Cell in JupyterLab to Receive Parameters

1. Select the cell you want to configure to receive parameters.

2. Click on the gear icon located on the right panel in JupyterLab. This will open the cell metadata editor.

3. Add a new tag:

   • In the metadata editor, locate or create a field named tags.
   • Add a new tag called parameters.

4. Save the changes and ensure the parameters tag has been added correctly.

The recommended practice is to define parameters in the first cell of the notebook. This ensures a clear structure, makes them easy to locate, and provides a centralized configuration that can be used throughout the notebook's execution.

Parameters can be defined in a Markdown, Raw, or Code cell, or even without explicitly defining a cell for this purpose. Parameter injection will automatically take place above the first code cell in the notebook. This provides greater flexibility when working with parameterization tools like Papermill or automating notebook execution in configurable environments.

2. Define Notebooks and Parameters

Provide a list of notebooks with input paths, output paths, and parameter dictionaries.

original_notebooks_path = './sample_notebooks'
processed_notebook_file_path = './processed_notebook'

notebooks_with_parameters = [
    (f"{original_notebooks_path}/1_Add.ipynb", f"./{processed_notebook_file_path}/add_executed.ipynb", {"params": [10, 5, 7]}),
    (f"{original_notebooks_path}/2_Subtract.ipynb", f"./{processed_notebook_file_path}/subtract_executed.ipynb", {"x": 10, "y": 3}),
    (f"{original_notebooks_path}/3_Divide.ipynb", f"./{processed_notebook_file_path}/divide_executed.ipynb", {"x": 20, "y": 0}),
    (f"{original_notebooks_path}/4_No_parameters.ipynb", f"./{processed_notebook_file_path}/no_parameters_executed.ipynb", {"inject_values": {"x": [2, 3], "y": [4, 5]}}),
    (f"{original_notebooks_path}/5_Multiply.ipynb", f"./{processed_notebook_file_path}/multiply_executed.ipynb", {"inject_values": {"x": [2, 3], "y": [4, 5]}}),
]

3. Execute Notebooks

Run each notebook with parameters and save the results.

notebook_execution_results = []
for input_path, output_path, params in notebooks_with_parameters:
    notebook_results = processor.run_notebook_with_parameters(input_path, output_path, params)
    notebook_execution_results.append(notebook_results)

4. Extract Variables from Notebooks

Extract variable data and display it in a structured format.

variable_list = []
for notebook_result in notebook_execution_results:
    if notebook_result:
        extracted_data = processor.extract_variable_data_from_notebook_cells(notebook_result)
        variable_list.append(processor.display_notebook_variables_and_values_extracted_from_notebook(extracted_data))

5. Retrieve the Variable Values from Every Notebook
