Hum, interesting, thank you very much ! Then as for neuran-fortran, I think I am understanding how to compile now. Using gfortran, I run the command 
gfortran mycode.f90 -o mycode -Lpath/to/lib -Ipath/to/include -llibrary.
It seems to work on my computer. Yet I the calculation space I am working on, hdf5 isn’t installed, so I have to figure out a way to do this. Thank you very much for your help !
