beso_main.py unable to run as macro

[ruzko]

Since I began using beso half a year ago, i haven't been able to 'run optimization' in fc-gui freecad macro, or run beso_main.py as a freecad macro at all.

I've found a workaround to this, by writing a conf file with fc-gui macro, and then running beso_main.py in the terminal.
After issuing the command python beso_main.py in the .Freecad/Macro/ directory, an empty window with title '11' shows up. Closing window '11', opens window '12', and so forth until i close window '15'. Only now, the actual optimization would start.

I experienced this problem while using Freecad 0.18, 0.19 and 0.20 in both Linux Mint and Manjaro.

Report view output when pressing 'run optimization' from fc-gui macro:

I run it successfully on Linux Mint 19.3 Mate with FreeCAD 0.20.25065 (not the latest). My only idea is that it could be due to line separators of the python files in macro directory. Some text editors enable "find and replace" from \r\n to \n  But I give it a little chance to be the reason. The issue with empty figures 11, 12... can be due to different version of the library matplotlib. Perhaps the older code will work 66f27f8 from where you just copy beso_main.py

I tried uninstalling the Retr3d workbench, and beso now runs properly as a macro

@fandaL you can use package.xml file to indicate what other addons this macro conflicts with
