Hi Olivier, There was a feature that I had included some time ago and that would be perfect here. The ma5 interpreter allows for the option "no_compilation=True" (the default is False). It would be sufficient to add this option to the get_MadAnalysis5_interpreter method, set it to True when the cards are created, and things should be fine. Please let me know whether it works.
