Continously error in Slicer3d when import pymeshfix library in module

[arpinerap]

I´m trying to use your pymeshfix library in Slicer3d with Python version 3.6.7 (default, Oct 23 2021, 23:20:53) [MSC v.1924 64 bit (AMD64). If I make the import in Python interractor, it works fine but if I add "import pymeshfix" to a module, Python Interactor send me continously an error message like:

Input port 0 of algorithm vtkTubeFilter(000001DB85805BE0) has 0 connections but is not optional.".

It´s something recurrent, tons of messages but nothing crash despite of this...

Thanks in advance!
