feat: speed up `requires_package` using caching by germa89 · Pull Request #3705 · ansys/pymapdl

germa89 · 2025-01-27T13:52:39Z

Description

requires_package is quite slow because of the attempt to import a package and the error handling.
This is the perfect case of using cache wrapper to avoid executing the importing function if the response is already given. I might be able to expand this to other parts of the library.

I do not expect massive performance improvements on the test library, although it is called quite a lot of times.
