We present the cosmological results with a CNN from the KiDS-450 tomographic weak lensing dataset, constraining the total matter density $\Omega_m$, the fluctuation amplitude $\sigma_8$, and the intrinsic alignment amplitude $A_{\rm{IA}}$.

The absolute accuracy of the final nonlinear power spectrum is comparable to one obtained with N-body simulations, i. e. $\sim 1\%$ for $k\lesssim 1\, h\,{\rm Mpc}^{-1}$ and $z\lesssim 3. 5$.

Correspondingly, our results suggest that AGN feedback is not strong enough in the simulation.
