# integrate on polytopes with latte : result is always equal 0

I would like to compute integral of polynomial functions on polytopes. I'm using Sagemath in a Jupyter notebook and I've also installed the latte-integrale package with conda. In the notebook, I manage to import "latte", define the polytope and the function, but the result of the integral is always to 0. My script is :

```
from sage.features.latte import Latte
Latte().is_present()
```

FeatureTestResult('latte_int', True)

```
P=polytopes.cube()
x,y,z = polygens(QQ,names='x,y,z')
f=x^2*y^2*z^2
P.integrate(f)
```

0

Thanks in advance!

Works for me in ubuntu with sage 10.1.beta3. Tell us your sage version, os, machine, etc.

I can replicate the observed bug in Ubuntu 22.04.2 LTS (jammy) with
