Significant Changes

Nbconvert 6.0 is a major release of nbconvert which includes many significant changes.

  • Python 2 support was dropped. Currently Python 3.6-3.8 is supported and tested by nbconvert. However, nbconvert 6.0 provides limited support for Python 3.6. nbconvert 6.1 will drop support for Python 3.6. Limited support means we will test and run CI on Python 3.6.12 or higher. Issues that are found only affecting Python 3.6 are not guaranteed to be fixed. We recommend all users of nbconvert use Python 3.7 and higher.
  • Unlike previous versions, nbconvert 6.0 relies on the nbclient package for the execute preprocessor, which allows for asynchronous kernel requests.
  • template_path has become template_paths. If referring to a 5.x style .tpl template use the full path with the template_file argument to the file. On the command line the pattern is --template-file=<path/to/file.tpl>.
  • Nbconvert 6.0 includes a new "webpdf" exporter, which renders notebooks in pdf format through a headless web browser, so that complex outputs such as HTML tables, or even widgets are rendered in the same way as with the HTML exporter and a web browser.
  • The default template applied when exporting to HTML now produces the same DOM structure as JupyterLab, and is styled using JupyterLab's CSS. The pygments theme in use mimics JupyterLab's codemirror mode with the same CSS variables, so that custom JupyterLab themes could be applied. The classic notebook styling can still be enabled with
jupyter nbconvert --to html --template classic
  • Nbconvert 6.0 includes a new system for creating custom templates, which can now be installed as packages. A custom "foobar" template is installed in Jupyter's data directory under nbconvert/templates and has the form of a directory containing all resources. Templates specify their base template as well as other configuration parameters in a conf.json at the root of the template directory.
  • The "slideshow" template now makes use of RevealJS version 4. It can now be used with the HTML exporter with
jupyter nbconvert --to html --template reveal

The --to slides exporter is still supported for convenience.

  • Inkscape 1.0 is now supported, which had some breaking changes that prevented 5.x versions of nbconvert from converting documents on some systems that updated.

We merged 105 pull requests! Rather than enumerate all of them we'll link to the github page which contains the many smaller impact improvements.

Significant Changes

Jupter Client Pin

The jupyter_client dependency is now pinned to >5.3.1. This is done to support the Parallel NBConvert below, and future versions may require interface changes from that version.

Parallel NBConvert

NBConvert --execute can now be run in parallel via threads, multiprocessing, or async patterns! This means you can now parallelize nbconvert via a bash loop, or a python concurrency pattern and it should be able to execute those notebooks in parallel.

Kernels have varying support for safe concurrent execution. The ipython kernel (ipykernel version 1.5.2 and higher) should be safe to run concurrently using Python 3. However, the Python 2 ipykernel does not always provide safe concurrent execution and sometimes fails with a socket bind exception. Unlike ipykernel which is maintained by the project, other community-maintained kernels may have varying support for concurrent execution, and these kernels were not tested heavily.

Issues for nbconvert can be viewed here: 1018:, and 1017:

Execute Loop Rewrite

This release completely rewrote the execution loop responsible for monitoring kernel messages until cell execution is completed. This removes an error where kernel messages could be dropped if too many were posted too quickly. Furthermore, the change means that messages are not buffered. Now, messages can be logged immediately rather than waiting for the cell to terminate.

See 994: for exact code changes if you're curious.

Significant Changes

Deprecations

Python 3.4 support was dropped. Many of our upstream libraries stopped supporting 3.4 and it was found that serious bugs were being caught during testing against those libraries updating past 3.4.

See 979 for details.

IPyWidget Support

Now when a notebook executing contains Jupyter Widgets, the state of all the widgets can be stored in the notebook's metadata. This allows rendering of the live widgets on, for instance nbviewer, or when converting to html.

You can tell nbconvert to not store the state using the store_widget_state argument:

jupyter nbconvert --ExecutePreprocessor.store_widget_state=False --to notebook --execute mynotebook.ipynb

This widget rendering is not performed against a browser during execution, so only widget default states or states manipulated via user code will be calculated during execution. %%javascript cells will execute upon notebook rendering, enabling complex interactions to function as expected when viewed by a UI.

If you can't view widget results after execution, you may need to select File --> Trust Notebook in the menu.

See 779, 900, and 983 for details.

Execute Preprocessor Rework

Based on monkey patching required in papermill the run_cell code path in the ExecutePreprocessor was reworked to allow for accessing individual message parses without reimplementing the entire function. Now there is a process_message function which take a ZeroMQ message and applies all of its side-effect updates on the cell/notebook objects before returning the output it generated, if it generated any such output.

The change required a much more extensive test suite covering cell execution as test coverage on the various, sometimes wonky, code paths made improvements and reworks impossible to prove undamaging. Now changes to kernel message processing has much better coverage, so future additions or changes with specs over time will be easier to add.

See 905 and 982 for details

Out Of Memory Kernel Failure Catches

When running out of memory on a machine, if the kernel process was killed by the operating system it would result in a timeout error at best and hang indefinitely at worst. Now regardless of timeout configuration, if the underlying kernel process dies before emitting any messages to the effect an exception will be raised notifying the consumer of the lost kernel within a few seconds.

See 959, 971, and 998 for details

Latex / PDF Template Improvements

The latex template was long overdue for improvements. The default template had a rewrite which makes exports for latex and pdf look a lot better. Code cells in particular render much better with line breaks and styling the more closely matches notebook browser rendering. Thanks t-makaro for the efforts here!

See 992 for details

5.4 on Github

Significant Changes

Deprecations

Python 3.3 support was dropped. The version of python is no longer common and new versions have many fixes and interface improvements that warrant the change in support.

See 843 for implementation details.

Changes in how we handle metadata

There were a few new metadata fields which are now respected in nbconvert.

nb.metadata.authors metadata attribute will be respected in latex exports. Multiple authors will be added with , separation against their names.

nb.metadata.title will be respected ahead of nb.metadata.name for title assignment. This better matches with the notebook format.

nb.metadata.filename will override the default output_filename_template when extracting notebook resources in the ExtractOutputPreprocessor. The attribute is helpful for when you want to consistently fix to a particular output filename, especially when you need to set image filenames for your exports.

The raises-exception cell tag (nb.cells[].metadata.tags[raises-exception]) allows for cell exceptions to not halt execution. The tag is respected in the same way by nbval and other notebook interfaces. nb.metadata.allow_errors will apply this rule for all cells. This feature is toggleable with the force_raise_errors configuration option. Errors from executing the notebook can be allowed with a raises-exception tag on a single cell, or the allow_errors configurable option for all cells. An allowed error will be recorded in notebook output, and execution will continue. If an error occurs when it is not explicitly allowed, a 'CellExecutionError' will be raised. If force_raise_errors is True, CellExecutionError will be raised for any error that occurs while executing the notebook. This overrides both the allow_errors option and the raises-exception cell tags.

See 867, 703, 685, 672, and 684 for implementation changes.

Configurable kernel managers when executing notebooks

The kernel manager can now be optionally passed into the ExecutePreprocessor.preprocess and the executenb functions as the keyword argument km. This means that the kernel can be configured as desired before beginning preprocessing.

This is useful for executing in a context where the kernel has external dependencies that need to be set to non-default values. An example of this might be a Spark kernel where you wish to configure the Spark cluster location ahead of time without building a new kernel.

Overall the ExecutePreprocessor has been reworked to make it easier to use. Future releases will continue this trend to make this section of the code more inheritable and reusable by others. We encourage you read the source code for this version if you're interested in the detailed improvements.

See 852 for implementation changes.

Surfacing exporters in front-ends

Exporters are now exposed for front-ends to consume, including classic notebook. As an example, this means that latex exporter will be made available for latex 'text/latex' media type from the Download As interface.

See 759 and 864 for implementation changes.

Raw Templates

Template exporters can now be assigned raw templates as string attributes by setting the raw_template variable.

class AttrExporter(TemplateExporter):
    # If the class has a special template and you want it defined within the class
    raw_template = """{%- extends 'rst.tpl' -%}
{%- block in_prompt -%}
raw template
{%- endblock in_prompt -%}
    """
exporter_attr = AttrExporter()
output_attr, _ = exporter_attr.from_notebook_node(nb)
assert "raw template" in output_attr

See 675 for implementation changes.

New command line flags

The --no-input will hide input cells on export. This is great for notebooks which generate "reports" where you want the code that was executed to not appear by default in the extracts.

An alias for notebook was added to exporter commands. Now --to ipynb will behave as --to notebook does.

See 825 and 873 for implementation changes.

Major features

Tag Based Element Filtering

For removing individual elements from notebooks, we need a way to signal to nbconvert that the elements should be removed. With this release, we introduce the use of tags for that purpose.

Tags are user-defined strings attached to cells or outputs. They are stored in cell or output metadata. For more on tags see the nbformat docs on cell metadata.

Usage:

  1. Apply tags to the elements that you want to remove.

For removing an entire cell, the cell input, or all cell outputs apply the tag to the cell.

For removing individual outputs, put the tag in the output metadata using a call like display(your_output_element, metadata={tags=[<your_tags_here>]}).

NB: Use different tags depending on whether you want to remove the entire cell, the input, all outputs, or individual outputs.

  1. Add the tags for removing the different kinds of elements to the following traitlets. Which kind of element you want to remove determines which traitlet you add the tags to.

The following traitlets remove elements of different kinds:

  • remove_cell_tags: removes cells
  • remove_input_tags: removes inputs
  • remove_all_outputs_tag: removes all outputs
  • remove_single_output_tag: removes individual outputs

Major features

In this release (along with the usual bugfixes and documentation improvements, which are legion) we have a few new major features that have been requested for a long time:

Global Content Filtering

You now have the ability to remove input or output from code cells, markdown cells and the input and output prompts. The easiest way to access all of these is by using traitlets like TemplateExporter.exclude_input = True (or, for example HTMLExporter.exclude_markdown = True if you wanted to make it specific to HTML output). On the command line if you just want to not have input or output prompts just use --no-prompt.

Execute notebooks from a function

You can now use the executenb function to execute notebooks as though you ran the execute preprocessor on the notebooks. It returns the standard notebook and resources options.

Remove cells based on regex pattern

This removes cells based on their matching a regex pattern (by default, empty cells). This is the RegexRemovePreprocessor.

Script exporter entrypoints for nonpython scripts

Now there is an entrypoint for having an exporter specific to the type of script that is being exported. While designed for use with the IRkernel in particular (with a script exporter focused on exporting R scripts) other non-python kernels that wish to have a language specific exporter can now surface that directly.

Comprehensive notes

  • new: configurable ExecutePreprocessor.startup_timeout configurable 583
  • new: RemoveCell preprocessor based on cell content (defaults to empty cell) 575
  • new: function for executing notebooks: executenb 573
  • new: global filtering to remove inputs, outputs, markdown cells (&c.), this works on all templates 554
  • new: script exporter entrypoint 531
  • new: configurable anchor link text (previously ¶) HTMLExporter.anchor_link_text 522
  • new: configurable values for slides exporter 542 558
  • improved releases (how-to documentation, version-number generation and checking) 593
  • doc improvements 593 580 565 554
  • language information from cell magics (for highlighting) is now included in more formats 586
  • mathjax upgrades and cdn fixes 584 567
  • better CI 571 540
  • better traceback behaviour when execution errs 521
  • deprecated nose test features removed 519
  • bug fixed: we now respect width and height metadata on jpeg and png mimetype outputs 588
  • bug fixed: now we respect the resolve_references filter in report.tplx 577
  • bug fixed: output metadata now is removed by ClearOutputPreprocessor 569
  • bug fixed: display id respected in execute preproessor 563
  • bug fixed: dynamic defaults for optional jupyter_client import 559
  • bug fixed: don't self-close non-void HTML tags 548
  • buf fixed: upgrade jupyter_client dependency to 4.2 539
  • bug fixed: LaTeX output through md→LaTeX conversion shouldn't be touched 535
  • bug fixed: now we escape < inside math formulas when converting to html 514
