Hi everyone, 

After installing yadedaily (which works) on my new computer running with  Ubuntu 16.04 (with xfce interface), I am trying to install Yade from the source code. I suceeded to install all the necessary packages except the "python-scientific" one, which give the error (in french sorry):

"sudo apt-get install  python-scientific
Lecture des listes de paquets... Fait
Construction de l'arbre des dépendances       
Lecture des informations d'état... Fait
Aucune version du paquet python-scientific n'est disponible, mais il existe dans la base
de données. Cela signifie en général que le paquet est manquant, qu'il est devenu obsolète
ou qu'il n'est disponible que sur une autre source

E: Le paquet « python-scientific » n'a pas de version susceptible d'être installée"

meaning that the package is missing or out of date or available only on another source. 

I tried to continue the installation without this package, it is compiling and create the executable of yade (after cmake, make and make install), but when I run it I get a long error:

"*** Error in `/usr/bin/python': realloc(): invalid pointer: 0x00007fbab345a820 ***

ending with:

First, can you confirm that it is due to the absence of the package python-scientific ? If it is the case, is there a way to install it on Ubuntu 16.04 ? If it is not the case and the problem is more complex, do you believe it is better for me to come back to Ubuntu 14.04, or would yade from source be compatible soon with Ubuntu16.04? 

Thanks, 

Raphael
