We present a computational study based on density functional plus dynamical mean-field theory calculations for the normal-state electronic reconstruction of pure and hole-doped ${\mathrm{NdNiO}}_{2}$ superconductors. Our results capture the $T$ dependence of the electrical resistivity, providing a many-particle interpretation of the emergence of pseudogaplike features at low energies as well as the weakly insulating regime seen in experiment. We show how Mottness manifests itself in the weak localization to bad-metallicity crossover due to strong correlation in the ${e}_{g}$-shell one-particle spectral functions and self-energies.
