Thank You Souvarine.
I am very stupid ; solid is used in the example, for the character...
So, I have tested with a part of my world and it is OK.
Now they are two levels, the first is visible but not solid, and the
second is not visible but solid, with no details and many cubes.
I load them so :
# level what you see, but no collisions :
level = soya.World.get("level_college")
level.solid = 0
scene.add(level)
# for collisions, but invisible :
level_c = soya.World.get("level_c_college")
level_c.visible = 0
scene.add(level_c)
You can see here :

but in French (I speak a little better French).
