Changelog v3.0.0

This is the first release to adhere to the SemVer and Conventional Commits specifications.

πŸŽ‰ Features

  • The report configuration was completely overhauled, providing a more intuitive API and fixing issues inherent to the previous global config.

πŸ› Bug fixes

  • Various issues could not be (easily) solved in the previous configuration architecture, are fixed in this release ([584], [644], [698], [720] and [724])

  • Fix crash with exotic characters ([707])

  • Fixed the way (sub)titles were shown in the report grids.

πŸ“– Documentation

  • Enforce QA using flake8 for documentation, for instance checking for backticks and enforcing black code style on examples.

  • Automated configuration documentation API.

πŸ‘·β€β™‚οΈ Internal Improvements

  • CI: mypy type checking was moved to the pre-commit hooks.

🚨 Breaking changes

The configuration syntax has changed!

The yaml configuration now requires the official syntax (e.g. null instead of None). The previously used configuration library could not handle comments with indentation - you are now free to use conventional yaml.

For the python configuration the set_variable method has been replaced by more intuitively accessing the configuration object. For example, you can now set the title in the following way report.config.title = "My title".

The docs provide additional examples.

Changelog v2.8.0

πŸŽ‰ Features

  • Expanded the Unicode analysis capabilities: next to the most occurring unicode scripts, categories and blocks, it’s now possible to inspect the most frequent characters for each of them.

  • ProfileReport.set_variable now accepts nested parameters such as report.set_variable("variables.descriptions", {"var1": "Identifier"}).

  • Ability to have descriptions of the variables alongside the descriptive statistics (#232, #402).

  • Config: Introducing config shorthands.

  • Config: plot.scatter_threshold allows for configuration above what value scatter plots are replace with hexbin plots.

  • Config: html.inline allows for rendering assets as vector images to package export as folder and file (similar to exporting a website). (#452).

  • It’s now possible to specify which interactions to compute to filter out un-needed interactions between columns (#451).

  • When the output_file is omitted in the CLI, it uses the input_file with HTML extensions. This can be useful when profiling of a complete directory from the command line, e.g. find . -type f -name "*.csv" -exec pandas_profiling {} \;.

  • Config: Split the vars.cat.check_composition in vars.cat.unicode and vars.cat.length for more control on the summaries.

  • Config: Included a new configuration sample file config_explorative.yml, including Text (length distribution, unicode information), File (file size, creation time), Image (dimensions, exif information).

πŸ› Bug fixes

  • Resolved color ValueError on Mac (#464).

  • Style: too many interactions overflowed tabs. Now they elegantly turn into a select control.

  • Unique variables are always uniform and have high cardinality, hence we can remove the redundant labels.

  • The counts for unicode properties were based on unique characters, instead of following the original frequency distribution.

  • Slimmed down the HTML by removing classes and more effective CSS.

Changelog v2.7.0

πŸŽ‰ Features

  • Reports are built in phases, see issue for details (#421)

  • The most occurring duplicates rows are included in the report.

  • ProfileReports can now be saved to and loaded from disk (for caching).

  • Explicit analysis duration is added to the reproduction section of the report.

  • Doc: this version introduces documentation powered by Sphinx. The previously used pdoc3 has been adequate initially, however misses functionality and extensibility.

  • Doc: Dedicated page for large datasets is created (#420).

  • Doc: The installation instructions have been extended, installation via conda would default to 1.4.1 (#449, #448).

  • CI: Linting, building the documentation and examples and uploading the package to PyPi have been automated using git flow and Github Actions.

πŸ› Bug fixes

  • warnings were not shown in the β€œwarnings” tab, but were at variable level (#389).

  • The β€œmedian absolute deviation” is now reported instead of the β€œmean absolute deviation” (#453).

  • Several style-related fixes for Jupyter lab and notebooks (tables, warnings, wide images).

  • pd.NAN introduced in pandas 1 now supported (#437).

  • The logic for calculating infinite values is now correct (#397).

πŸ‘·β€β™‚οΈ Internal Improvements

  • The number of progress bars is reduced. The progress bars are now grouped by build phase (e.g. describing dataset, building report structure, rendering report, exporting to file).

  • The progress bars provide more information about the current step to the user #434).

  • Invalid correlations coefficients do not cause it to drop the complete variable anymore, instead the plot now propagates the NaN (#417).

  • Performance: type inference test now short-circuit, as visions does by default.

  • Performance: the numerical summary is optimized to use numpy directly, instead of slower methods provided by pandas.

  • Config: dynamic histogram bins are now disabled by default default for better default computational performance (#441).

  • Config: type inference to warning when date variables are processed as categorical is set to False by default for being a bottleneck for larger datasets.

  • Warn: the user is warned that the to_widgets does not work in Google Colab, which doesn’t support ipywidgets properly (#462).

  • Cln: Moved ProfileReport out of __init__ to it’s own class file.

  • Cln: removed the output_file parameter form examples.

  • Cln: the HTML representation of the footer and wrapper are moved out of ProfileReport to the report structure.

  • Cln: the imports are automatically ordered with isort.

⚠️ Deprecated

  • Doc: the pdoc3 documentation will be removed in the future.

  • Config: using the config globally is deprecated. In the future, the configuration will be tied to the ProfileReport.

🚨 Breaking changes

  • Doc: the example HTML reports were removed from the repository (still available in the gh-pages branch and documentation).

  • The recoded β€œcorrelation” was removed for not being informative enough to justify it’s costs.

⬆️ Dependencies

  • Requirements now correctly excludes pandas 1.0.0, 1.0.1 and 1.0.2. Either user pandas <1 or >= 1.0.3.
