Labels and Milestones

Each issue should have at least one label from the Type and Status section assigned.

Type (#cc317c)


Issues that introduce new functionality. Original post should include the following information:

  • Description of desired functionality
  • A (prosaic) description of a use case
  • Optionally add suggestions/ideas about how to implement the feature. As always, PRs are welcome. :)

Issues about something not working as intended. Original post should include the following information:

  • Platform (operating system, architecture)
  • Version of package in question
  • Steps suitable to reproduce the problem
  • Error message/console output
  • If you are willing to share: log files

In case of an error within the documentation the above requirements can be omitted.

Indicates that the issues topic has been addressed before and all discussion/comments should happen in the referenced issue instead.
Indicates that the issue is less about actual code/functionality but addresses a general (design) question that needs to be decided upon before an implementation can be considered.
Used to track multiple related issues.

Topic (#fbca04)

Issues without a specific topic assigned deal with general functionality. The main purpose if these labels is to allow contributors with specific skill sets to find issues fitting them.

Issue does not deal with functionality itself but with user interaction.
Issue deal with visual representation of functionality.
Issue does not require actual coding or even necessarily python knowledge at all but deals with documenting the project itself. It may be used to indicate improvements to the code’s documentation, in which case a basic familiarity with the language and code layout is highly desirable. However, it may also be used for issues dealing with front end user facing documentation that elaborates on how to use the package in a plain natural language.
Issues related to project package releases.
Issues related to the general project setup.

Status (#159818)

Labels that indicate the status of an issue. Their provide a quick and easy answer to whether the issue is actionable or not.

Decision needed
Tickets that need a design decision are blocked for development until a project leader clarifies the way in which the issue should be approached.
Information needed
This label indicates that the issue has not enough information in order to decide on how to go forward. See the documentation about our triage process for more information.
Help needed
Designates issues which seem to require a certain skill currently not available to the core developers. Such issues are unlikely to be solved unless a contributor with the required skill-set steps forward to help out. Giving pointers to domain specific resources or best practices may already be enough. This does not necessarily imply that all the actual coding has to be done by the person providing the desired skill.
The issue has been screened by the core devs and may be worked upon at your leisure.
This issue can only be addressed once another issue has been resolved. The cause may be an internal issue or external dependency.
In progress:
Issues currently worked on. If you want to join work on it please coordinate with its assignee to achieve the best possible solution and avoid duplicate work.
Issues that are not considered within the general goals of the project. A reference to said previous discussion/issue should be given.


Labels that did not warrant their own group.

Ready for review
Pull Requests that are considered complete. A review by at least one core developer is required prior to merging it.
Good First Bug

This label marks tickets that are easy to get started with. The ticket should be ideal for beginners to dive into the code base, indicating low-hanging fruits. These tickets generally should fit the following requirements:

  • No comprehensive knowledge of the entire code base needed.
  • No particular 3rd party library familiarity required.
  • Most likely does not involve long term effort.
  • No elaborate design decisions involved.
