I think You got the point, I tried to check the L1 and L2, but it seems after some iterations it goes behind my machine's precision. I have to check it more carefully to be sure about it.

To be honest, I suspect the issue is in some other part of youre codes.

On the other hand, you can also code a simple matrix-vector product using a "1.0" entry for all and compare C++ and python results.
