Cannot import Delphes in python macOS

[Giacomo Boldrini]

Hello Delphes experts.
I cannot manage to import libDelphes in python. I succed in loading Delphes in root from the console at the second try (because first try it gives me errors):

---

However I cannot do the same at all in python. Suppose I create a script in the exact same directory where libDelphes.so is stored then if I run:

I get that error. I checked and libHist is in my libPyRoot library so what am I doing wrong? I export everything in my bash_profile as I think I should but nothing. Is it something to do with the new library issue about apple (not caring of LD_LIBRARY_PATH or DYLD...) or am I missing something?

Is there a way to read Delphes outputs without loading libDelphes using python?
Thank you very much I look forward to your answer,

Cheers, Giacomo
