Jupyter NbModel Client

Client to interact with a Jupyter Notebook model.

To install the library, run the following command.

pip install jupyter_nbmodel_client

We ask you to take additional actions to overcome limitations and bugs of the pycrdt library. Ensure you create a new shell after running the following commands.

pip uninstall -y pycrdt datalayer_pycrdt
pip install datalayer_pycrdt

Usage

1. Ensure you have the needed packages in your environment to run the example here after.

pip install jupyterlab jupyter-collaboration ipykernel matplotlib

2. Start a JupyterLab server, setting a port and a token to be reused by the agent, and create a notebook test.ipynb.

jupyter lab --port 8888 --IdentityProvider.token MY_TOKEN

3. Open a Python REPL and execute the following snippet to add a cell.

from jupyter_nbmodel_client import NbModelClient, get_jupyter_notebook_websocket_url

with NbModelClient(
    get_jupyter_notebook_websocket_url(
        server_url="http://localhost:8888",
        token="MY_TOKEN",
        path="test.ipynb"
    )
) as notebook:
    notebook.add_code_cell("print('hello world')")

Check test.ipynb in JupyterLab.

5. The previous example does not involve kernels. Put that now in the picture, adding a cell and executing within a kernel process.

from jupyter_kernel_client import KernelClient
from jupyter_nbmodel_client import NbModelClient, get_jupyter_notebook_websocket_url

with KernelClient(server_url="http://localhost:8888", token="MY_TOKEN") as kernel:
    async with NbModelClient(
        get_jupyter_notebook_websocket_url(
            server_url="http://localhost:8888",
            token="MY_TOKEN",
            path="test.ipynb"
        )
    ) as notebook:
        cell_index = notebook.add_code_cell("print('hello world')")
        results = notebook.execute_cell(cell_index, kernel)

        assert results["status"] == "ok"
        assert len(results["outputs"]) > 0

Check test.ipynb in JupyterLab.

You can go further and create a plot with Matplotlib.

from jupyter_kernel_client import KernelClient
from jupyter_nbmodel_client import NbModelClient, get_jupyter_notebook_websocket_url

CODE = """import matplotlib.pyplot as plt

fig, ax = plt.subplots()

fruits = ['apple', 'blueberry', 'cherry', 'orange']
counts = [40, 100, 30, 55]
bar_labels = ['red', 'blue', '_red', 'orange']
bar_colors = ['tab:red', 'tab:blue', 'tab:red', 'tab:orange']

ax.bar(fruits, counts, label=bar_labels, color=bar_colors)

ax.set_ylabel('fruit supply')
ax.set_title('Fruit supply by kind and color')
ax.legend(title='Fruit color')

plt.show()
"""

with KernelClient(server_url="http://localhost:8888", token="MY_TOKEN") as kernel:
    async with NbModelClient(
        get_jupyter_notebook_websocket_url(
            server_url="http://localhost:8888",
            token="MY_TOKEN",
            path="test.ipynb"
        )
    ) as notebook:
        cell_index = notebook.add_code_cell(CODE)
        results = notebook.execute_cell(cell_index, kernel)

        assert results["status"] == "ok"
        assert len(results["outputs"]) > 0

Check test.ipynb in JupyterLab.

[!NOTE]

Instead of using the clients as context manager, you can call the start() and stop() methods.

from jupyter_nbmodel_client import NbModelClient, get_jupyter_notebook_websocket_url

kernel = KernelClient(server_url="http://localhost:8888", token="MY_TOKEN")
kernel.start()

try:
    notebook = NbModelClient(
        get_jupyter_notebook_websocket_url(
            server_url="http://localhost:8888",
            token="MY_TOKEN",
            path="test.ipynb"
        )
    )
    await notebook.start()
    try:
        cell_index = notebook.add_code_cell("print('hello world')")
        results = notebook.execute_cell(cell_index, kernel)
    finally:
        await notebook.stop()
finally:
    kernel.stop()

[!NOTE] To connect to Datalayer collaborative room, you can use the helper function get_datalayer_websocket_url:

from jupyter_nbmodel_client import NbModelClient, get_datalayer_websocket_url

async with NbModelClient(
    get_datalayer_websocket_url(
        server_url=server,
        room_id=room_id,
        token=token
    )
) as notebook:
    notebook.add_code_cell(CODE)

Uninstall

To remove the library, run the following.

pip uninstall jupyter_nbmodel_client
