A toolset to accelerate Jupyter notebook workflows
Compute and use Jupyter notebook cell outputs in other notebooks and scripts with just a couple lines of code.
- Split ordered steps across multiple notebooks, picking up the most recent state information with each new notebook
- Prototype and organize workflows entirely in Jupyter notebooks without having to manage script exports
- Improve performance by reducing overheads from notebook servers and unused code cells
Conveyor currently only supports Jupyter notebooks written in Python. It is important to ensure that you have the version of Python (and any dependencies) used in your notebooks also installed locally, or on the machine using this library.
For quick and simple access to values in a prior notebook:
conveyor.run_notebook("conveyor/examples/Sample Calculations I.ipynb", import_globals=True) # all notebook globals pushed to conveyor.nbglobals with import_globals flag from conveyor.nbglobals import x, y, z, fig print(y)
Conveyor can also provide you with any information available in a prior Jupyter workspace.
results = conveyor.run_notebook("conveyor/examples/Sample Calculations I.ipynb") # Cells are zero-indexed, only code cells are counted code_cell_idx = 1 # Get a cell's source code code = results[code_cell_idx]['code'] # Get a cell result cell_result = results[code_cell_idx]['result'] # Get cell stdout cell_stdout = results[code_cell_idx]['stdout'] # To get any variable available in notebook x = results.getvar('x')
There are options for running notebooks that can be used to optimize notebook execution, or stitch notebooks together in pipelines.
from conveyor.multinb import Pipeline ... data_processing = Pipeline() data_processing.add_notebook(filename="conveyor/examples/load_data.ipynb", carry_vars=['df']) data_processing.add_notebook(filename="conveyor/examples/process_data.ipynb", carry_vars=['magic_number'], start_cell_idx=3) # Add custom intermediary steps def transform_magic(from_state): to_state = dict() to_state['transformed_magic_number'] = -1 * from_state['magic_number'] return to_state data_processing.add_transform(transform_magic) # Get output of selected variables from each stage results = data_processing.run()
This package is available on pypi. Install it using pip with
pip install jupyter-conveyor
Conveyor is only compatible with Python 3.5 and above.
