  SolveFailure

  The current project's Python requirement (>=3.10,<4.0) is not compatible with some of the required packages Python requirement:
    - scipy requires Python <3.13,>=3.9, so it will not be satisfied for Python >=3.13,<4.0

  Because no versions of scipy match >1.11.1,<2.0.0
   and scipy (1.11.1) requires Python <3.13,>=3.9, scipy is forbidden.
  So, because double-pendula depends on scipy (^1.11.1), version solving failed.

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties

    For scipy, a possible solution would be to set the `python` property to ">=3.10,<3.13"
