Uploading Jupyter notebook checkpoints#

Once you've installed the Neptune–Jupyter extension, you can snapshot your code by uploading notebook checkpoints.

Tip

You can later download a checkpoint from Neptune with the Download button in Jupyter.
You can also download checkpoints as .ipynb files directly from the Neptune app.

Manual upload#

To upload the current notebook as a checkpoint:

In the Jupyter top navigation, click Upload.
Select a project from the list.
Optionally enter a checkpoint name and description. This makes it easier to identify and compare checkpoints in Neptune.
Click Upload checkpoint.

Click the link in the confirmation message to open the notebook in Neptune.

You can save notebook checkpoints automatically whenever you create a Neptune run in a notebook cell.

To connect your notebook and run, log the notebook to Neptune by clicking Upload in the Jupyter navigation.

After that, whenever you create a run in the notebook with neptune.init_run(), the checkpoint will be logged automatically.

Missing notebook checkpoints

When you restart the Jupyter kernel, your notebook checkpoints may not be saved to Neptune nor connected to the Neptune runs you created.

To fix that, re-activate your notebook by clicking Activate in the Jupyter navigation menu.
